Those do it yourself places suck because their brushes are pretty severe, and you never know what’s stuck in the brush (like a bunch of abbrasive sand from the redneck cleaning off his mudder just before you).
When I’m not washing in my driveway because it’s too cold or I’m too busy I usually hit one of the Laser Washes. 100% touchless and do a decent job drying. Bring a microfiber to dry what it misses. The down side being since they’re touchless they may not get all the baked on bird shit off.
I have a whole wash system.
Power wash car, wolfgangs foaming gun which covers the car in soap, then microfiber mit and rinse.
I only go to delta sonic in the winter because of their underbody sprayer.
Like stated above, California wash is good, Touchless.
It will remove about 95% of the dirt on your car. but you will still have that road grim on there.
There is a place down on main street in Buffalo near Canisius run by a bunch of black guys. They do a great job. Everyday they make $2000 pieces of crap look like $7000 pieces of crap. That’s a talent in my book.
