FAQs
Using a Foam Maxx foamer allows you to put the chemical where you need it. The foam will also remain in contact longer with the dirt/grease/oil to ensure thorough cleaning when you rinse.
We tell our customers to start the high pH (alkaline) detergent at a strength of 1:20.
Streaking will result on the vehicle surface.
Use a pressure washer to knock off the large chunks. If possible, allow surface to dry as the chemical works best when applied to a dry surface. If you do not have time to let the surface dry, you may need to increase the strength of the chemical.
You can use a debugger product like EXT372 Bug-Be-Gone. Simply apply on areas with insect residue like a pre-treatment. Without rinsing, continue with either one-step or two-step touchless cleaning.
