Separate your glasses
If you don’t have a lot of shelf space in your house -or maybe because it looks better that way- you stack your glassware on top of each other. Sometimes, they can stick together after a long time in that position. And you know that pulling on them will only end in disaster.
If you are careful and handle them well, you can use WD-40 to loosen the grip on each other. It makes them slippery, so repeat the application: be careful! This is an easy way to release them and not drink from a stack of stuck glasses. Just remember to rinse them after.
