Clean Showerhead
If you have an old showerhead, it's time to ask when the last time you cleaned it was...a while right? The hack for this is easy. Just fill a plastic bucket with vinegar and soak the appliance in it for a few hours or overnight. Once you wash off the vinegar, it should be good as new!
Potato Screwer
If you've misplaced your screwdriver, don't worry, there's a hack for that! Another option is using the pointed tip of a vegetable peeler. It won't be as quick, that's for sure, but it'll work just the same. Make sure to clean it before using it for veggies again though...
