Our windows are our view to the world, but sometimes they can get cranky – or uncranky and stuck. I found an easy fix. I got some 0000 Stella wool and sprayed a little silicone oil on it. Next, I cleaned out the channels after opening the window. Lastly, I sprayed the gear at the base of the arm. Now they work great. Use of silicone spray is key here because of it resistance to water – not regular WD40.
