I've standard MINI black stripes on my F56 - my car in midnight black and so often looks dirty down to dust and I sometimes use some good quality waterless cleaner just to remove said dust. I sprayed a small amount onto the bonnet and some of it caught the stripes and they're now 'stained'
I've tried cleaning the stripes using polish etc but still they're marked - I fear new stripes will now be the order of the day but it seems crazy that they won't withstand a simple clean???? Gonna have words with the dealer as to me they are not fit for purpose if you can clean them????
Thoughts lovely people...
