Re: Best Wheel Cleaner for mobile detailer without hose
another vote for the pump sprayer. Before I started to use that, I used some gallon sized container or sunnyD container, washed then very well and fill with water. I used Meg's APC+ which is no foam and easy rinsed off. so my procedure:
Meg's APC+-->scrub-->then wash with ONR(you will have to use ONR to wash the car anyway)--> then a light rinse with the water in milk container.
This way you will only need 1 gallon of water for small cars and 2-3 gallon for large ones.
