Tom’s Way – How To Change a Car Wash Foamy Brush

Tom Allen, our Senior Technician, recommends you change your entire self-serve foamy brush assembly twice a year: once in the spring and once in the fall. Having a brand new brush going into the busy winter car wash season is crucial. When spring arrives, you’ll likely need to replace your brush assembly after the heavy use of the winter. Changing the foamy brush before it becomes too worn down improves both visual appeal and performance. When brush bristles start to separate, as in the picture to the right, foam will not be dispersed evenly. While it may still get the job done, customers don’t like to see chunks of foam! You want to maintain a smooth flow of foam and bright, shiny equipment that will wow your patrons and keep them coming back to your self-serve car wash.

Getting Started

It’s easy to change your own foamy brush assembly! Here’s what you’ll need:

If your handle and hoses do not show much wear and tear, they may be able to survive another car wash season. Use your discretion – but be sure to to change the foamy brush itself!

Tom Breaks It Down

By following the steps below, you can replace your old self-serve brush with a nice, tight, new brush that’s ready for use!

Step 1
  1. Using two adjustable wrenches, remove the entire foamy brush assembly from its connection point at the boom. Wrap the Teflon tape around the new hose’s threads, and attach the new hose to the boom. Tighten with a wrench.
Step 2

2. Apply Teflon tape to the low pressure swivel end of the foamy brush hose. Thread it by hand into the brush handle. Use a wrench to tighten so it’s snug, but don’t tighten it all the way.

Step 3

3. Attach the new brush head to the end of the brush handle. Spin it until it’s snug.

Step 4

4. Gently stand on the brush and use a wrench to tighten the handle. This will also tighten the brush itself!
