COMMERCIAL PROPERTY CLEANING TIPS

COMMERCIAL PROPERTY CLEANING TIPS

This video features commercial property cleaning tips on a large, metal building with some unique challenges.  There is a lot of limestone split face block which is very dirty because of its highly porous nature.  Another description folks use for this is decorative block.  Notice in the video the before and after photos that will give you a great feel for this project and how effective our cleaning methods turn out.

ADJUSTABLE CONE NOZZLE

I explain how we use an adjustable cone nozzle for cleaning this decorative block.  Using a dedicated pump with the adjustable cone nozzle allows you to apply a gentle mist for this porous surface.  We apply a 50% bleach mix mist so that the mix is not bouncing off the wall or running down onto the ground.  I also show how we use an extension wand for this application method.  We use the KINGSLINGER soft wash system to apply the mist mix.  You can find the Kingslinger specifications and purchase options here.

DON’T FLOOD THE SURFACE

There is no need to flood a surface with bleach mix.  This is especially true when applying solutions for roof cleaning.  The goal is simply to get a nice, small coat onto the surface so that the bleach and the oxygen from the air can work together.  In golf lessons, they usually advise something like “don’t try to kill it.”  In other words, overpowering your swing is counterproductive.  This also applies to the amount of bleach mix you put on the surfaces that you’re cleaning.  Don’t kill it or overpower it.

COMMERCIAL PROPERTY WALLS

We could see both black and green mold or mildew colors on the metal walls.  This is very common on surfaces where there is little exposure to the sun.  Our first attempt at downstreaming was ineffective, so the Kingslinger came in handy for this part of the job as well.  We apply a 30% with the 10 GPM Kingslinger soft wash system with the 0020 nozzle.  There are more tips so be sure to check out the entire video!  If you are interested in learning more about all the training options we provide, check out our extensive FAQ page.

Commercial Pressure Washing

COMMERCIAL PRESSURE WASHING

There are several unique challenges that arise with COMMERCIAL PRESSURE WASHING projects.  These challenges are generally set apart from an average residential home.  However, some of the challenges can be found on larger mansions and larger residential properties.  These COMMERCIAL PRESSURE WASHING tips and tricks will help better prepare you for cleaning commercial properties.

COMMERCIAL PROPERTY PROTECTION

Any time you clean close to grass, plants, or landscaping, it is very important to PRE WET the surface and the ground below.  So as you pre wet the surface with 100% water, you also pre wet the grass, plants and landscaping.  After pre wetting, you apply your cleaning solution, which is usually about a 40%-50% mix.  Do not flood coat with this solution, but rather provide a nice medium coat of mix.  When we rinse the building, that water will also help dilute the mix and protect the plants.  You will then spend even more time watering the grass to ensure that solution does not damage any plant life.  The area will most likely be pretty soggy when you walk across it.  Special attention should be paid to any shrubbery or trees that are close to the building.  Previous amounts of rain water will also affect the amount of water needed for pre wetting to prevent damage to plant life.  If sprinkler systems are present, this would also be an important factor for commercial pressure washingGet even more property protection tips here.

PREVIOUS CLEANING SERVICE

Are there any signs of previous exterior cleaning?  In this particular case, we notice the use of a wand.  While sections closer to the ground are clean, how high they were able to reach was limited.  It’s important to document this in the event that damage was caused previously that you are not responsible for.  Commercial Pressure Washing surface damage is fairly common so be on the look out for this.

COMMERCIAL CLEANING SOFT WASH METHOD

Our cleaning starts with the KINGSLINGER soft wash system.  We apply a 50% mix after pre wetting in a cross way pattern.  It’s important to apply a nice even coat to avoid dry spots on the surface.  Depending on the severity of the stains, it may take two or three coats to reach maximum clean.  Using a soft wash strategy is the best approach for commercial pressure washing jobs.

COMMERCIAL CLEANING SURFACE IMPERFECTIONS

When evaluating commercial pressure washing projects, consider whether the property has been well maintained.  If that is not the case, there may be damage to the surface which exists under some stains.  In fact, some organic and biological growth may have penetrated the paint, exposing the surface.  So it’s important to document and communicate this to the customer.  This way, you are not held responsible for preexisting damage which might show after cleaning.  Again, this is why the soft wash method is critical for cases like this.
