Car Wash Wall Cleaner

Klean-Wall cleaner has made the once dreaded task of cleaning walls a simple and easy  job.  Just spray Klean-Wall on and rinse off.  Klean-Wall cleans fiberglass, brick, block, glazed tile, and metal surfaces, as well as painted walls. With clean bay walls you will attract more business!
Q: What is the proper way to clean the walls of a car wash?
A: Take an eight foot dry section of the wall.  Using a pump up garden sprayer filled with properly diluted cleaning detergent, spray the detergent from the bottom of the wall moving upward.  By starting at the bottom of the wall and moving upward you will eliminate streaking.  Allow the detergent to dwell on the wall for 3-5minutes.  Using a power washer of at least a 1000psi start spraying the wall with water.  Remember to keep the nozzle only 2-3 inches from the wall to get maximum power from the power washer.   The wall should be clean now.  If you come across a stubborn spot reapply a second application of detergent and agitate with a stiff bristled brush.   Always were safety glasses, rubber boots, and rubber gloves when handling chemical detergents.

Q: What is the importance of setting up a maintenance schedule, what is that schedule? 

A: A maintenance schedule is a routine cleaning schedule.  Owners who don't clean their walls for a year have a very difficult time making them look new again.  A car wash owner should wash down their walls with a mild soap and high pressure power washer weekly.  They should perform a deep cleaning every 2-4 weeks depending on how busy the car wash is. Deep cleaning requires the use of a specialized acidic detergent. Rainy days are great days to clean car wash walls. 

Q: Why do they get so dirty and hard to clean? 

A: Car wash walls get so dirty because of a combination of factors.  The cars come in soiled with road grime, oil, dirt, etc. The high pressure gun used in the car wash blows this road grime off of the car and onto the walls. The road grime that is now on the wall is mixed with surfactants, oils and hard water from the car wash soap and water.  This cocktail is allowed to dry on the wall. After several days of this cycle your car wash ends up with a hard water/dried soap coating several layers thick. The only way to remove this coating is with a specialized acidic detergent. 

Q: What are common mistakes made in cleaning car wash walls? 

A: The biggest mistake people make about cleaning car wash walls is not cleaning them enough.  If cleaned under a maintenance program your walls will never get to the point they cannot be cleaned. 

Q: If an owner is in a jam and needs to clean the walls, but is out of cleaning product, do you have any suggestions what could be used? 

A: If you were out of a cleaning product to clean walls and had to use something readily available use the tire and engine cleaner in your chemical room.  This chemical is alkaline and is good at removing soil and grease that may be on your wall from a busy weekend of car washing.  When you are ready to perform your every 2-4 week heavy duty wall cleaning you must use an acidic cleaner.  A specialized acidic cleaner has a balanced amount of phosphoric acid, surfactants, and chelating agents that penetrate the soil/hard water which is dried on the walls.  A product like Klean-Wall will save an operator countless hours in the task of cleaning their car wash walls. 

Q: What are some of the toughest stains or spots to remove and why? What should be done to clean them? 

A: Grease on the wall: use tire and engine cleaner or a degreaser.  Colored stain from a colored soap or wax: use bleach to remove the stain.  Hard water and scale buildup on your walls or equipment: use Klean-Wall.

Frequently Asked Questions
Question:Hi there, I am following up the question I asked below on March 17th, but to date I have not yet received a response: I am curious if you would recommend this product for use on Airlift Polycarbonate over head doors, and if not perhaps another product like JBS Bay & Wall Cleaner (Part # JB5502). Thank you. - KEVIN (03/22/2021)
Response:If not used properly, products of this nature tend to etch or cloud the glass and/or poly material. Our recommendation is to contact Air-Lift for a product they would use for cleaning their specific material.
Question:Are the ingredients listed anywhere on this page? - Ken (01/31/2021)
