What do you recommend to spray onto the garage door tracks to clean them, reduce noise, and cause a smoother run? How often should I apply it? I've read where a silicone lubricant is recommended, but I don't really know what that means. Thanks
Garage door tracks don't need to be lubricated, certainly not with any kind of grease - it just attracts dirt. If there is grease, mineral spirits should get it off.
You can use spray silicone lubricant. It doesn't last all that long but does help with the squeaks. Hit the hinges while you're at it. One of many brands available at the hardware store.
the dry lube for bike chains works well. doesn't gather dirt/dust.
Thanks for the suggestions. I'll try them both.
