I never said my method was more environmentally friendly
True, but also OP was asking for recommendations on a touchless wash,
not whether or not they should be using one at all.
Anyway...
It is also definitely valid for
@gglockner worth sharing environmental impacts and/or any legal factors. City of Bothell, King County, and many others state the impact on our water systems.
Taking the environmental point above, I will also stray from OP asking specifically about touchless, and share that my preferred method is to bucket wash in a Brown Bear self service car wash, bringing my kit from home (
2 gallon sprayer, bucket of warm soapy water with a couple of clean mits) to clean the car, then paying for and using their rinsing sprayer. I usually do a final spray of
Wash Wax All when I get home and wipe down the clean microfibers. I've used this method with my 2011 WRX and have had desired results each time.
I cringe thinking I pay $3 - $4 to basically use their pressure washer, but at least the dirty water is collected on site and recycled.
I will say my post is very biased, but I swim in Lake Washington regularly, and I have water access just two blocks away. Our storm drain and local streams are right by my home.
