Maybe it's brand-specific, but I never had luck with milder stuff like dish soap on BF Goodrich. Had to jump to that Blech White and acetone. Ugh.
Sometimes you store them and they don't come back out lol
Dad was a stickler on touching a car, "never touch the paint, and if you must, touch the chrome"Other people (usually morons) wiping their hands over your nice paintwork...or leaning on the car.
This is just about always non-car people doing it.
Every episode of Wheeler Dealers I have watched - Mike rubs his hands across the hood of the car just after it is finished.....that really grinds my gears....and Ed China (Tall Man) putting new parts on a filthy location...clean the damn work area first you munter.
That's just as bad...chrome has pores which draw in moisture...and your hands are covered in acidic moisture.
Fantastic work! For a second there viewing the first photos, thought you were making an upside down convertible.
