My sister recently got her 2024 330i in white. She loves it to death, her friends purchased a car wash pass at Petro Canada here in Canada, and they split the cost. 1 wash per day for a year and is split among the 3 of them. She gets a wash like every 2 days or something. But the thing is some of the car washes are not touch less. They are touch with bristles, and she showed me a video and I just cringed.
Then some are touchless, but regardless, aren’t the soaps in touchless washes bad for the vehicles clear coat? I am thinking of just cleaning it for her by hand and such. I’m mad at her because she isn’t taking care of this car she spent lots of money on.
Go to the auto detailing sub Reddit. There is a huge spectrum of how to take care of your car. I personally never go to any automated wash because the brushes that touch your car will leave micro scratches and over time your paint will just look less good. On the other hand, the gold standard is two bucket system whereby you dip the mitt in a rinse bucket and then the soap bucket - both with grit guards - to minimize swirl marks and micro scratches. Obviously that takes way more time and is way more expensive. Most people use the machines. You have to do what works for you.
This is the only answer.
