Lube for car window tracks

[JackOfDiamonds]

Lots of old cars get slow windows. Sometimes you have to change the motor, but it seems like you could extend the life by lubing the edges of the window with something.

Is there anything that works to reduce friction of glass on rubber, without gumming up and getting even worse? What about silicone spray? Teflon or graphite dry lube? Candle wax? Car wax?

I have used spray silicone with good results

This stuff is great on rubber. One tube will last you a lifetime. Definitely shop around for the best price.

Stay away from petroleum products and rubber as it will deteriorate rubber. However, what jobo1004 mentioned or any Silicone paste or dielectric grease will be fine. You can choose 3M, Honda, Permatex, Superlube. As long as it's Silicone you will be good to go.

I had silicone spray for my sunroof, as the rubber would deteriorate, as Quality said.

Money ahead of the game, if an older car to pull the door panel and the regulator. Clean it and regrease with superlube. For the rubber interphase you can use talcum powder(baby powder). Good luck!

I have used this.

You need to open up the door inside panel and regrease everything. Doing it from outside won't do much. Spend maybe an hour each door. You'll be surprised how good everything will work afterwards.

A friend did the above in his his 1986 E28 5 series BMW. Sticky windows would go up and down swiftly.

Honda Shin etsu or gummi pflege. Also the rubber or felt inside the door needs to be removed and cleaned

if the car is old, the regulator needs to be cleaned out and regreased. I have seen the grease harden in Japanese cars

I use silicone spray also. Down below inside the door I use silicone paste, 3M to be exact. Spray silicone works but if your channels are dirty it's only a temporary solution. Best to clean the channels (down in the door especially) then lube.

I use the regular SuperLube for lots of general purpose stuff. But I've never used it for the window channels. The regular stuff is just a "synthetic grease". Don't quote me, I believe it's not petroleum based so should be good on rubber but I don't think it's a silicone base grease. SuperLube does sell a different grease that is silicone based.

silicone furniture polish spray works well . just spray it on the channels put the window up and down a few times then clean off any excess .

I bought some stuff at lowes called super slick slick stuff, I just tried it and worked so far on one of my old death traps on the farm.
