use beeswax wrap to open jars.

Use beeswax food wrap for a zero waste jar opener | Litterless

In addition to the standard hitting it against the counter, running it under hot water, drying it off, shaking your hands out and trying again, sometimes you just need a little help opening a jar. I was excited to see a tip recently that beeswax food wrap can also be used to open a jar! It’s grippy and a bit sticky, just like the rubber kind of jar opener. I’ve used it a couple of times and each time it’s worked like a charm. Sometimes what you need is already in your kitchen drawer, it seems.
