While at the factory for warranty issues the techs there recommended/used Pledge furniture polish to condition the seals, spray onto a rag & wipe them down. Used it, actually the dollar store imitation Pledge, for 6+ years on my last 5er on all the rubber seals/gaskets, worked great, dirt doesn't stick to it, easy to apply, much less mess than the talcom powder, won't harm the rubber & you can also use it inside on the furniture & cabinets, 1 product several uses.

Thank you! Sounds like a plan
