FAQ
Common questions.
Will Purge damage my wax or ceramic coating?
No - Purge is non-caustic and safe on waxes, sealants and ceramic coatings when used as directed at 10:1.
How do I dilute it, and how long does a bottle last?
Mix 1 part Purge with 10 parts water. A 1L bottle makes 11L of ready-to-use prewash - around 10 full washes.
How do I apply it?
Through the Electric Foam Spray Bottle, a pump sprayer or a foam lance. Spray on, let it dwell for 2-3 minutes and rinse before it dries. Avoid hot panels and direct sunlight.
Should I use Purge or Deep Freeze Snow Foam?
Purge is the stronger cleaner - reach for it on heavier road grime and traffic film. Deep Freeze is a pH neutral snow foam that's perfect for lightly soiled, protected cars. They also work brilliantly together: Purge on the dirtiest areas first, then foam the whole car.
Is it safe on wheels and trim?
Yes - Purge is safe on paint, wheels, glass, rubber and plastic trim, making it ideal for bumpers, arches and other grime traps.
