Talking How can I remove dried paint and rust stains from black rubber side window gaskets?

Any suggestions for how I can remove dried paint and rusty stains (see image below) from the black rubber gaskets that surround the roll-up windows and side vent windows of an 83 pickup? I'm repainting the front cab so I removed all of that stuff and want to make it look nice before I put it back. Besides the dried paint, etc. the rubber is still in good condition.

Thank you.

I need to remove some dried paint from the front turn signal lens too so I will definitely try lacquer thinner. Have you used it on porous rubber stuff like those window gaskets before?

Only to clean the mess i made that kind of ran onto them when getting the paint off the truck. Ive used wd40 before as well as a turtle wax product called Liquid Ice to restore the rubber after cleaning it. Luckily i have a friend in west florida who has or had, new rubber gaskets for the windshield and rear window. I have a couple sets of extra door to get the other stuff off of. I think Cory85 has used vaseline to help restore old rubber trim pieces as well.

If lacquer thinner turns out too aggressive, try 100% silicone dielectric grease, or the silicone spray can. Silicone (not caulking) seems to make pretty much anything "UN-stick" and reconditions natural rubber. I used it to revive my window rubber surrounds.

First I would soak the gaskets in ordinary white vinegar. It's really cheap and gets rust off things. Then I would clean it with 00 steel wool and degreaser. Wipe it down with a generous amount of a tire dressing such as Armor All . I used a Meguiars version that I can't remember the name of. Geez. I looked for a good picture and all I found was this. It had rust spots and was all white and chaulky. It's from a parts truck.

Just an update here... Lacquer thinner worked well for removing the old paint from the rubber gaskets and everything else, so thanks for the suggestion.
