I too have this problem. I can usually just crank a little bit of tension on them and wait until they POP open.
What is glycerin??
I also didn't know what glycerin was so I googled it and saw it was used in make-up and available at CVS. So I stopped at the pharmacy today and asked the girl behind the counter if they had glycerin, and she took me to a rack of glycerin suppositories. It was very embarrassing, but the good news is that apparently that stuff can get anything unstuck.
I'm sure this has been discussed in the past but I couldn't find it. I have "screw-out" frameless windows and they stick something terrible if I don't open them for a long time. In fact, there is one that I cannot open at all right now. Is there some product I can put on the rubber seals to keep this from happening? I don't want something that is going to leave a greasy smell if possible.
I am just curios if this is a problem for others and how they handle it. Thanks.
