Apply a light coat of lube to my car door's rubber seal (which made an unacceptable noise when brand new and I don't think the dealer helped much) and it's gone ! Works wonders. I'm sure others have said this before, but: Clean the rubber seal first, then work gently around the rubber seal while wearing rubber/nitrile gloves. Wipe/spread excess lubricant from surface. Be careful not to get it on the paint. A little really goes a long way. Much luck!
