Swinger Tight Window Issue

After I installed all my glass and new weather strips in my 68 mine were very stiff also, I wiped down all of the channels with lemon pledge. I know it sounds weird but I sprayed the lemon pledge on a clean rag and inserted the rag into the glass channels and I wiped them down a few times. No more stiffness they roll up and down just fine now. I have always used this method for my home window tracks and my door wall tracks when I clean them, lemon pledge does not collect the dirt that usually clogs up the tracks, oils do. Give it a try you just might like it. Smells good to.
