It is not practical for me to wash my car living in Brooklyn so I'm trying to figure out the best solution to keep my Black A6 clean. It is parked outside, so it tends to get dirty rather quickly - especially this time of year with the pollen. There is a hand wash right near me that does a fantastic job - just a bit pricey to do it regularly.
Are any 'automatic' car washes safe? There are a ton in my area - many of them are brushless. From looking inside the washer it appears some have what appears to be massive towels that wash the car. Will these types of washes ruin the finish on the car?
