    Default Rejuvenating old rubber trim

    Is there a recommended way to rejuvenate original weathered rubbers as found on a DS? I'm talking inter-body panel seals, door rubbers, window weather strips, etc. Some I will have to replace as they are too far gone, such as the boot lid to rear window rubber, but most of them appear to be sound apart from a little chalkiness.
    I've scrubbed forty five years worth of grime off them with a stiff bristle scrubbing brush, but has anyone had better success with any sort of scouring pad or paste etc?

    I've heard silicone grease is good for rejuvenating old trim and seals, I've not got round to trying it but I intend to, unless someone knows of anything better..

    The subject reminds me of the joke about the regimental prophylactic.........

    Try glycerin. Works well on certain rubber compositions (door seals for example).

    Petroleum Jelly. Old school stuff but works. Rub in with your hands and fingers, buff off, and repeat every few months until it's "re-lubricated" the rubbers, vinyl trims etc. Thereafter you can re-do it less often. And your hands will feel better too.

    If all these do not work I used black silicone rubber smoothed over all the cracks, cuts and missing pieces in the rubber.

    Also good on the dashboard top for the late DSs. As per advice from Hayzehuths - 'n ya can't argue with that!

    Wurth make a specific rubber spray, which is very good. I think it's called rubber care.

    Understated and overpriced.
    Works a treat, like most Wurth product.

    Thanks for all the tips, guys. I tried some petroleum jelly and it did indeed seem to make the lightly weathered rubbers look like new, but I think some may be too far gone. I suspect I may have to buy more new ones than I was originally hoping.

    Cheers
