best shampoo for dark colour?

[der passat]

hi

What do you think is the best shampoo for dark cars?
I've "meguaird" my car, and yesterday I've washed the car with ntx, sorry but terrible!
In the sun everyware swirls, first with my riwax products I didn't have that...
So use gold classe now or bubble stuff(pink gelly shampoo)?
What do you think folks?

Kind regards

Hi Bert,

The best car wash for any car is a car wash that adds lubricity to the car wash process to help make the surface slippery while your washing the paint and one that contains cleaning ingredients that will clean effectively without being an overkill like detergent washes are.

If you're seeing swirls and scratches in the paint that were not in the paint after washing the car, then the problem is not Meguiar's car washes, including NXT Car Wash as these products don't contain anything abrasive in them.

This would mean that the scratches were in the paint to start with and washing just revealed them to your eyes, or the way the car is being washed, or the tools used to touch the finish, either/or during the washing step or the drying step are instilling the scratches.
