Industrial Pressure Washer Maintenance And Tips

Like all machines, an industrial pressure washer will last longer and require less maintenance when used in ideal conditions. Although industrial devices are much more resilient than the alternatives designed for home use, here are some rules to follow to ensure a long service life.

  • Do not remove the machine from the frame on wheels and do not place it directly in the water or on a wet surface.
  • Follow the manufacturer’s recommended maintenance schedule.
  • Always inspect your unit for fluid leaks and visible hose damage prior to each use.
  • Always take time to dry the pressure washer if it gets wet. This can lead to corrosion and a shortening of the service life.
  • Inspect and clean the sprayer nozzle to avoid any clogs or inconsistent flow

Among the types of industrial pressure washers, the most important thing to consider is the intended use. The power, size, and operation required for cleaning the fine instruments of a production line are completely different from those required for cleaning smog and dirt on the facade of a building. Unique Industries offers mobile and stationary units of multiple sizes, if you are unsure which unit is best for you just give us a call.

While a large water spray on the central unit can harm specific pressure washers, other heavy-duty models can withstand rain. Looking for an IP rating on your pressure washer is a useful rule of thumb for determining whether or not it can handle wet circumstances. While gas-powered pressure washers are more water-resistant than electric pressure washers, they still contain an engine, which might cause problems if used in the rain.

There is a reason why the machines are labeled “Do not use the machine to clean yourself” because the high-pressure water jets can damage the parts of the machine. The same goes for heavy rainwater, where droplets fall at such a high velocity that they can damage small pipes and other parts. Of course, this does not mean that you should quickly put an umbrella over your pressure washer at the first drops – but it’s worth paying attention to weather conditions and avoiding work during a thunderstorm.

Industrial Pressure Washer Maintenance Schedule?

Like all machines, industrial pressure washer maintenance will be based on a schedule and amount of use. Although the device is much more resilient than the alternatives designed for home use, there are some things to know to keep your industrial pressure washer properly maintained:

  • All cleaning units have a specified pressure washer maintenance schedule, so if you have multiple units, their maintenance schedules could be different.
  • The specified pressure washer maintenance schedule is broken up by the amount of time the unit has been run for.
  • If you skip maintenance steps, problems could compound quickly and it will greatly shorten the life of your cleaning unit.

There is no other cleaning equipment on the market that functions as well as these mobile and fixed devices. Unique Industries creates cutting-edge Kem-O-Kleen hot water pressure acid cleaning systems that dynamically allow customers to execute a variety of tasks more quickly. For building restoration, industrial cleaning, masonry cleaning, and even acid etching for Architectural Precast and GFRC, Kem-O-Kleen systems are utilized across the country to speed workloads and create safer work conditions.

If you have questions about pressure washer maintenance on our machines or expected lifespan when properly they are properly maintained give us a call so we can help.

Industrial Pressure Washers

Industrial pressure washers are ideal for removing dirt, stains, paint  and other debris from buildings, brick, concrete and asphalt. In many cases, they are also used for acid etching, GFRC etching, finishing architectural precast products, chemical masonry cleaning and disinfection when the introduction of chemicals is required. These machines are used in many industries, such as manufacturing, food processing, and construction. How do industrial pressure washers work? What are the advantages of purchasing? We explore these questions in this article.

Almost everyone is familiar with pressure washers, if not from other sources, then from self-service car washes. But these devices are not the same as the industrial units we are talking about. Key differences include: the ability to introduce chemicals, a constant flow of heat and higher pressure capabilities.

Another difference is that we build our industrial pressure washers or chemical etching systems with premium materials and commercial grade components. Stainless steel axle and frame, two-wire braid/wrapped pressure hose, stainless steel wand pipe, commercial rated engine and pump, and stainless steel recirculation tank are among the premium materials used to build our industrial pressure washers.

We only use 304, corrosion free alloy, instead of the cheaper, corrosion prone variety used by many industrial pressure washer manufacturers. Due to our rigorous engineering and testing each part of the machine provides: ease of use, performance, durability and safety in a rugged environment.

Applications of  Industrial Pressure Washer

Industrial-grade power washers are utilized in many industries because of their ability to quickly clean even the most special surfaces while providing a superior finish than other washing units. One of the most common industries to use industrial power washers is the commercial construction industry, as there are many areas of application like architectural precast, masonry cleaning, acid etching, GFRC etching and more.

Stationary Cleaning Units

Other common applications include:

  • Airports: To improve the safety of arriving and departing aircraft, large high-pressure cleaners are used to remove rubber and paint deposits from runways. In addition to cleaning aircrafts and concrete in hangers.
  • Municipalties: Graffiti removal is performed by municipalities using high-pressure cleaners with chemical agents like our MK Series Mobile Cleaning and Chemical Etching Systems
  • Ports and ships: All water-affected areas of harbors are infested with algae, including ships and walkways and engine rooms which require constant cleaning for safety and maintenance reasons.
  • Buildings: commercial building owners use pressure washers to keep their buildings clean, to etch concrete and GFRC applications.
  • Masonry cleaning: Masonry restoration and maintenance uses heated high-pressure water and chemical washing techniques to maintain the exterior surfaces of buildings.


There are numerous benefits offered by our high-pressure washing units, including: 

  • Portable or stationary, depending on the needs of the user.
  • Requires less manpower
  • Provides a superior finish
  • Can be used in small spaces while minimizing splash or over spray
  • Allows for the introduction of acid or chemicals
  • Is more cost-effective compared to traditional methods
  • Water pressure and temperatures are more consistent.
  • Commercial trucks and construction equipment
  • Mining/oil & gas

Restoring Brick Buildings in 2021

Brick buildings can be the most spectacular and beautiful structures. Though brick is durable and relatively easily maintained than cut stone or wood, some maintenance is necessary to keep the brickwork looking optimal.

Many older properties lack the upkeep necessary to preserve their appearance. For these buildings, restoration may help keep the buildings in good condition, improve neighborhood appearance, and improve resale value.


If you have a vintage brick building that needs restoration, you’ll need to plan before starting the project. You should first assess your building’s state and determine whether the mortar that holds the brickwork together is worn out. This is something that frequently happens.

Brick mortar can begin receding, cracking, or spilling between the joints of bricks over time. If not attended to, the mortar can fully break and lead to the collapse of the wall.


Before starting on a project like this, you’ll need to make sure you have all the materials necessary. Assembling all the materials before you start will make a difficult project much easier.

  • Safety glasses
  • Dust mask
  • Waterproof gloves
  • Mortar mix
  • Brick trowel
  • Hammer
  • Wheel rake or jointer tool
  • Flat utility chisel
  • Contouring tool
  • Pointing trowel
  • Whisk broom

If you lack these tools, don’t try to bumble through the job on your own without them, and don’t be afraid to call a professional before that happens!


Brick restoration can be more complex than you might think, as different brick structures are made of varying materials. Thus, a one-size-fits-all approach to restoring brick buildings is not suitable.

It would help if you took the time to make sure that you have the right specialized cleaning products to clean your brickwork. Soap and water will not be sufficient, and the average hardware store might not have salespeople with the expertise needed to point you in the right direction. Most masonry companies sell the cleaning products that you’ll need.

The replacement mortar will need to be compatible with the historic mortar to prevent a stark difference in color or mortar joint size after re-pointing. Mortars that are incompatible not only look dissimilar, but they can also damage brickwork through cracking spalling (deteriorating brick), and interior rotting of the mortar.


Before beginning, make sure you have safety equipment to minimize harm. This will include proper clothing, shoes, gloves, mask, and glasses. Always prioritize safety.


Using a hammer and chisel, about an inch of the old mortar will need to be removed. If there is damaged mortar that runs even deeper, chipping may need to continue until a solid base is reached.

In the worst situations, bricks may have to be removed and re-set with a new mortar. Cases with cracked mortar can also require careful procedures, including relief cuts made with a chisel or angle grinder. After the old mortar is properly removed, loose particles should be brushed out with a whisk broom before moving on.


Mortar should be mixed until it’s similar in consistency to peanut butter. It should rest for at least 10 minutes before being remixed. It then will be ready for use. Small batches should be mixed at a time, as the mortar starts drying out after 30 minutes.

You can use a trowel to push the mortar in between the bricks, filling the horizontal sections before the vertical ones. Use small amounts of mortar, as using too much can get it on the brick face. The mortar should be packed tightly, and deeper joints can be filled in multiple stages.

After the first stage, a wheel rake or jointer can be used to even out the mortar or add more as needed. Once that’s done, excess mortar on the bricks should be scraped away with a mortar brush.


There are many ways that brick restoration can go wrong, some of which involve inappropriate cleaning methods. These are just a few to keep in mind:

Don’t sandblast. This is a cleaning method that uses a machine to propel sand, glass, and other abrasives onto a hard material. Sandblasting can be used for concrete, but it’s one of the worst things that can be done to brick structures.

Although it would remove dirt and grime, sandblasting can destroy the brickwork and irreversibly damage the building. Some contractors argue that dry abrasive cleaning is harmful, but that wet abrasive cleaning is safer. This is not true–abrasive cleaning is never a good preservation option.

Don’t use high-pressure spray. Like sandblasting, these can also harm your building. This can be appealing because high-pressure water cleaning can seem like an effective way for one person to clean a building, but the high pressure can loosen the old mortar. Masonry can also be stained when cleaning chemicals are pushed too far into the brick to be rinsed out.

Don’t use chemical or water treatments during times when temperatures can go below freezing. This can introduce moisture into masonry surfaces. When liquid freezes, it will expand, which can cause cracks in your bricks.

Don’t use waterproof coating everywhere. Though waterproofing is essential in small increments, too much waterproofing can trap water inside the masonry. Waterproofing is not in itself a full solution for your brickwork.




Brick buildings can look brilliant when they are properly maintained and cared for. Restoration can be done on your own, but it’s a work-intensive process, and you can damage your intricate brick structures if you don’t do it properly. At Unique Industries, we can help with your restoration and provide help with ongoing maintenance to keep your brick building looking majestic and stately.

Graffiti Removal From Bricks

Unwanted graffiti and vandalism of a commercial building not only damages its fabric but also the reputation of a business. It gives off the impression that a company doesnt care about its public image, which can put off prospective customers. Some types of graffiti in residential buildings can contribute to social unrest by giving the impression of high crime rates in the area or gang-related activities.

Removing graffiti at the earliest restores the exterior of your building to its original state and shuns such perceptions. However, removing graffiti from brick can be challenging because of its uneven surface. Its porosity also means the applied paint is absorbed, making it difficult to scrape or wipe off.

But theres no cause for alarm. Here are the simple steps to follow when removing graffiti from bricks.


Step 1: Safety First

Some of the chemicals used in cleaning graffiti have dangerous fumes that can have adverse effects on the lungs when inhaled for long or cause skin problems when you come into contact with them. To protect your eyes from the chemical, put on safety goggles and also wear a face mask to avoid breathing the chemicals fumes.

Work gloves to protect your hands from the corrosive chemicals are also vital.

Step 2: Chemical Application

The spray paints used in graffiti art are strong and potent. Youll need some removal chemicals to get rid of the graffiti easily. There are numerous solvent solutions available in the market for graffiti removal, and you can find them in your local stores or from reputable online shops. After finding the right product, all you need to do is apply the solvent to the graffiti as per the manufacturers directions.

Step 3: Wait

After application, let the chemical sit before you can start scrubbing. Follow the manufacturers recommendations on how long the solvent should sit. However, if not indicated, the time should depend on the prevailing conditions. Let the chemical sit for a longer time if the paint is highly saturated, the brick is extremely porous or the temperature is cold. Proceed to scrub with a brush to loosen the paint. Make sure to thoroughly scrub the entire area, removing as much paint as possible.

Step 4: Pressure Wash the Area

Pressure wash the area using a wide, fan tip pressure washing nozzle. A pressure washer is highly recommended for graffiti removal on bricks because bricks are highly porous, and it might be difficult for the graffiti remover formula to reach all the paint. The pressure washer helps remove the clinging paint.

Step 5: Repeat if Necessary

Leave the wall to air dry. If there is still some stubborn paint remaining, repeat the process until all the graffiti has come off.

Its important to note that you should avoid using harsh acids or a metal bristled brush to clean the graffiti. They both etch the brick, and there are chances the metal bristles from the brush could leave rust stains behind. However, if you want to etch the bricks, do so to the entire wall to ensure it matches.

In your quest to remove graffiti, you can consider hiring professional graffiti removal services. But if you choose to remove the graffiti yourself, ensure you have the right products. At Unique Industries, we offer the highest quality pressure washers to help you in your quest

We can meter chemicals directly to the hot water stream, thus making it more effective while not using too much chemicals (or wasting them).

We stock different models of cleaning units to meet different clients unique needs.

Concrete Etching Machines

The World’s Best Precast Concrete Etching Systems

There is no better finish for concrete than acid etching. Acid etching sparkles compared to the dull aggregate of sand-blasting and say goodbye to silica dust, wormholes, efflorescence, and other issues. And there is no better way to acid etch than with a Kem-O-Kleen.

That’s why there are Kem-O-Kleen systems in place at 70%+ of the nation’s largest architectural precastors and FRC locations. Multiple unit installations, strong repeat purchases, and our specialized experience are further testimony to the product’s effectiveness.

  • Cut etching time to less than half that of traditional methods – quick pay-back on investment.
  • Thorough, consistent etching – very effective on detail where acid can pool or miss coverage using traditional methods
  • Use less chemical to do the job – designed for muriatic acid
  • Better finish – aggregate not dulled as with sandblasting
  • Precise control of chemical quantity applied
  • Rugged durable construction – designed for the job site
  • 200’ of full jacket hose – covers plenty of areas
  • A variety of models to fit all applications and budgets

High volume operators prefer the power of the MK7 and SK8 to keep production moving. Ornamental, FRC and smaller panel plants often select the smaller output of the MK3 and SK4 for their great etch. We are proud to have played a role in the many awards our customers have earned over the years.


Enhancing concrete finish with a concrete etching machine

In precast concrete finishes, acid etching is commonly applied to structures that have light to medium exposure. Acid etching removes the surface of the concrete and exposes the fine and coarse aggregate underneath by using a dilute hydrochloric acid solution. 

In addition to removing years of sediment, acid etching also gives a structure a brand new look by eliminating years of deposit. Concrete with acid-etched surfaces weathers better than concrete with form lines.

Concrete etching produces a fine, sandy surface similar to limestone or sandstone, with the cement paste and sand being the dominant elements visible on the surface.

Unlike unfinished building materials, acid etches concrete has a unique yet natural appearance for building exteriors that meet today’s trends. The quality of the mold used to produce precast is essential to ensuring that this surface will have a limited number of voids.

A precast plant may achieve an etched finish by soaking the element in a solution of acid and then scrubbing it to remove the outer skin about a week after removing it from the mold.

Precast concrete elements that are etched, prevent chloride from infiltrating the reinforcement due to the advanced manufacturing techniques. Acid etching w/KOH can be performed very quickly after the elements are removed from the mold. Consistency is important., try to etch all panels around the same time, post-mold removal.
