Limescale/acid rain stains on rubber trim

Iraklis F.C. · 24 Apr 2021 at 13:05

Good evening to all, the last few months our car has these spots/stains on the rubber trim around the windows, i have tried some silicone sprays etc to get rid of them as well as washing the car real good. Nothing works, have anyone else been in the same situation and successfully treated those stains? pic follows.

Have you tried one of the "back to black" sort of solutions?

Iraklis F.C. · 24 Apr 2021 at 13:33

no, there isnt any other solution?

I'm not really sure, I was just thinking they're pretty cheap at around £10 per bottle so maybe worth a shot

try some white vinegar or citric acid solution , this usually shifts limescale water marks,
a few times a year I usually clean the seals using a damp cloth rubbed on bar of soap, then rinse
and then re-apply gummi pfledge to keep seals supple and avoid them being ripped/stuck with frost
- back to black or silicone is not (really) the right product.

AutoGlym Bumper and Trim Gel.

Nothing really shifts those other than temporary IMO.

I've had limited success with a mixture of Showroom Shine and then Autoglym Vinyl and Rubber Care (other similar products will work as well).

so far i've tried with MA-FRA's faSPOILER spray and it did absolutely nothing at all. Also tried with vinegar on cotton, nadda.

I'd try soap too (I mean bars, not washing up liquid) too - it's possible the colour mottling is silicon oil and soap may gently shift it .

this is the gummi fledge I use ... ran out of the toothpaste bmw stuff years ago.
