Clear wrap / plastic wrap. Whatever you call it, you'll definitely have something like this in your kitchen. But if you have a large bowl that you want to get in and out of frequently, using a plastic shower cap with an elastic band would be a better idea so you can reuse it all the time.

Its perfect for containers that are large. The folks over at The Kitchn suggested this, and while some think its an old grandmother's tip in the kitchen it seems like its all new again now! Give it a shot! Just don't reuse them while you're taking a shower.
