You may be just the guy to help me with my glass slider, vinyl framed.
I try to keep the track fairly clean, but lately it has become harder then ever to close. Seems to have lost its' "glide". Anyway - Someone told me to never use any kind of grease or oil to improve the resistance. They claim it will just attact more dirt and cause more problems. Any suggestions as to the best way to clean it so it slides easily again??
