Drinking Glasses Stuck Together

When glass glasses get stuck together, it can be challenging to separate them, lest one or both break. I solved this by carefully pouring a small amount of vegetable oil between them and letting them sit overnight for the oil to disseminate.

Then, I looked for a place where I could move the inner-stuck glass just a bit, and that was enough to allow me to separate them. Work carefully. After this, if you are stacking them for storage, place a strip of paper towel between them.
