One-Step Touchless Cleaning
- Clean your semi-trailer from front to back and in small vertical sections (8-10 feet wide)
- Step 1: Apply a high pH (alkaline) detergent to the vehicle surface using a Foam Maxx foamer
- When applying the chemical, foam it on from the bottom of the vehicle to the top of the vehicle
- Step 2: Allow for a short dwell time 45-60 seconds
- If you are washing a vehicle outdoors, ensure you do not allow any chemical to dry on the surface of your truck
- Step 3: Use warm water (90°F – 100°F) for your high-pressure rinse and rinse the vehicle section from top to bottom
- Maintain your high-pressure nozzle within 18 inches of the surface and a spray angle of 15° – 45°
- Repeat Steps 1-3 until your truck is clean.
- The best high pH product to use for one-step cleaning is HEL100 Hellcat or THU100 Thunderbolt
