How can I get my window seals back to normal?

[Urban Sports]

Afternoon,

My car went to the dealers the other day for some warranty work and they gave it a service wash and the window seals have gone like this



I've only just noticed or I would have said something to them, is there a product or tip that can sort them out?

Cheers

Usual strong TFR mix has tarnished the rubber. You can try using a bumper trim gel to restore the finish, but it will fade eventually. Personally I would take it back and get new rubbers!

A decent all purpose cleaner, rinse, hand dry and then dress twice with Einszett (1Z) Gummi Pflege. Job done.

that could well and looks like it needs new rubbers , and most/all products will be masking hiding the problem , Gtechniq C4 would be the best solution and would need recoating around 12-24 months.
