I have all the tools, lotions, potions, etc. Several shelves full of shit and have my own profile on Autogeek because I'm a loser. Have done some insane level of detailing on several cars (full wet sanding and all that), used to detail on the side for money, yada yada yada.
Do you use a pressure washer on your cars?
Not really. Never directly. I have a foam cannon setup and quit bothering with it since, in reality, all that method really does is pre-soak the panels on the car. It doesn't actually make it so you can spray foam and, blast foam off, and the car is clean. Looks cool in the YouTube videos, but the hassle getting all that stuff set up isn't worth it. If you want dirt to release/blast off of the paint really easily you need to have a ceramic coating on the paint.
I used to do the two-bucket method for washing which is one bucket of soapy water, one bucket of clean water. You use the clean water bucket to rinse the wash mitt after cleaning a section of the car at a time. The problem I found with that method is that by rinsing the mitt in a bucket of clean water you introduce a bunch of 100% water back in to the soap bucket and end up diluting the soap bucket with too much water which can impact the lubricity that the soapy water is supposed to have at a proper dilution.
So now I just use a grit guard in the bottom of my soap bucket and scrub the mitt against it after each panel. Does a good job of keeping the actual dirt at the bottom of the bucket rather than it getting back on the mitt and then rubbing against the paint.
Typing this out, I realize how nerdy this all sounds. This is the tip of the spear with how wonky some of this car detailing stuff can get.
