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.
BMW Manufacturing plant in Spartanburg SC uses a car wash with spinning soft touch brushing to wash their new cars. But nothing ever goes through with gritty dirt on it. I’d say touchless is OK at a gas station to knock the dust or pollen off. We use a Sonic Suds wash on our 2023 5 Series. https://sonicsudswash.com/ Just remember, hand washing can be bad as well. The rags most places use are terrycloth type material that will grab and hold grit and dirt if dropped on the ground. (Swirl City) These premium type washes like sonic suds use closed cell foam technology in brushes has allowed for cleaner, shinier cars. In closed cell foam brushes, disconnected, microscopic bubbles in the foam prevent dirt and liquid from seeping into the brush. Just some food for thought.
