Most of our car wash places, in the West Midlands: this is my experience visiting, over 10 years of co. cars.
A golf or Audi pulls in with blackout windows.
Every car washer and the boss man ( if he’s there) disappear for 10 minutes.
They all come back out, then the cars take 30 minutes to be washed instead of 5 minutes, a lot of jovial pushing and spraying each other, general horseplay and tomfoolery, then they all stand in a corner sharing some chocolates and crisps.
No idea what was going on.
Suffice to say haven’t used one since the black California collection and the pdi man rubbing my brand new paint work with a bottle of spray and a dirty rag.
Citrus pre wash.
Jet wash. With a new short handled trigger.
autoglym polar blast.
Jet wash.
Wash with mcquers glove and hair brush’s. In two buckets, and polar wash.
Jet wash.
Then polar seal and 5 new microfibre cloths.
After a year, it comes up with no swirls, scratch’s and looks like it left the factory.
