Koch Chemie greenstar staining trim
 
Hey all I've got staining on my rubber trim from using Koch Chemie greenstar at 10 parts water to 1 part product.

How can I resolve this?

Will BH Autofoam stain trim? (What dilution is recommended for exterior in pump sprayer? Is it 4:1 to 10:1?

Thanks

It seems some people have encountered staining and are blaming it on auto foam in recents weeks, not something I have ever experienced on various cars.

It's usually 4% PIR with auto foam so 40ml in 960ml water equates to 4%.

Any ideas on how to remove staining from the trim?

Thats wrong.....4%....is not 40ml....its NOT based on how much your lance bottle holds....

Unless he uses a pump sprayer :)

Interested to know how I can get the staining off if possible :)

Robbi it was me that wrote the BH auto foam review for DW covering both snow foam and pump sprayer so I am pretty sure my numbers are correct [emoji6]

Benfr that's correct, my numbers were for use via a pump sprayer, I thought that was obvious but I guess I should have mentioned it.

What sort of trim is it that is stained? Is it painted?

Did you have any dressing on the trim? Sometime the foam degrades the dressing and looks patchy. In this case just rub the trim with some higher concentration cleaner (Greenstar or whatever) and clean it completely.

No dressing as car is only 2 years old and trim looks fine usually! :)

I feel like cleaning it with GS would just dull the whole trim!
