    Best product for treating rubber door seals?

    Guest-only advertisement. Register or Log In now!
    I'm aware that I should avoid silicone based products when treating the rubber door seals, but does anyone have any specific product recommendations for me?

    I've heard Krytox is good but I don't think it's the kind of thing you can find just anywhere.

    Someone also mentioned dishwashing liquid is good - comments?

    Rubber’ Seals

    The seals on most vehicles are no longer made of natural rubber; vehicle manufacturers use a specialized synthetic material called ethylene propylene diene monomer (EPDM). Real rubber, or blends containing real rubber, just cannot endure the direct exposure to sunlight (ultraviolet light) and the harmful-to-rubber oxidizing gases in our atmosphere.
    The soft seals around doors, windows, and sunroof’s hood and trunk are constantly subjected to thermal flex and compressed all the while being subjected to a hostile environment. To remain functional, they must stay flexible and require protection from the environment. The surfaces can be cleaned using a damp micro fibre towel and Iz einszett 'Plastik-Reiniger' Door and window seals must be treated 3-4 times a year. Use Iz einszett Gummipflege to treat all seals and caskets.

    Alternative products-
    1. Swissvax Seal Feed-Gum Feed (contains glycerine) to treat all seals and caskets.
    2. Gummipflege Stift - It applies directly from the bottle like a shoe polish; when it dries it creates a dark matte seal, durability measured in months it has a little sponge on top of the bottle so you always get the right amount of product on your weather-stripping or rubber seals. Once applied to rubber they will take on a dark but natural shine. Use bi-annually to provide UV protection to avoid rubber from hardening or freezing – Detailer’s Domain
    3. Zymol Seal a natural plant anti-oxidizing agent, it will prolong the useful life of the seal by restoring the original moisture and resist tearing and sticking
    4. Wurth Rubber Care Gel Stick- a silicone-free, biodegradable, and water repellent

    Most detail forums go this route - so I have some myself :P Its one of those things that if it works great, you never know - but if you dont use it, you will probably notice about a year too late.

    Just be careful to not press hard on your rubber trim. It has a pointed plastic nozzle in the middle of the sponge. I pressed hard and it left lines on my rubber trim :-( its better to press and massage on the sponge and nozzle with your fingertips and then apply to rubber trim.
