Use Eggshells for This Surprisingly Helpful Kitchen Hack

Tags:

Blenders are great for smoothies and sauces — but the blades tend to get dull with use. Sharpening the blades by hand is a hassle, replacing them is just expensive. So what is the solution? Eggshells. That’s right!

I sharpened my blender blades with them, and I’m here to share how you can sharpen yours the same way, saving time and money — as well putting would-be trash to good use!

How to use eggshells to sharpen blender blades.

Using eggshells to sharpen the blades in your blender couldn’t be simpler. According to a tip from food writer Shifrah Combiths, freeze your eggshells until you’re ready to use them. Then put them in your blender, add enough water to cover the eggshells, and run your machine until they’re completely broken up. Once you’re done, dispose of the eggshell paste in the trash or your composting bin.

(Do not put this paste down your sink drain or garbage disposal — you’ll clog or even ruin your pipes.)

Wash your blender thoroughly with soap and water afterwards, and you’ll be ready for (some razor-sharp) action!

I was a bit skeptical going into this hack. But as someone who makes a green smoothie almost every single day, I knew I had to try it out. I actually have two blenders at home, one of which is very old. I was thinking of donating it, so this was the perfect opportunity to test out this trick.

Once I had a few eggshells, I ended up lightly rinsing them and sticking them in the freezer for about 30 minutes. Combiths says you don’t have to clean yours before freezing, but I wanted to get rid of the egg residue. (I didn’t think eggs would taste good in a green smoothie!) I followed her instructions, adding water and blending the mixture on high speed, then dumped the contents in my trash can and thoroughly washed the blender.

One of the issues I’ve had with this blender is that I constantly have to stop and start it while making my smoothies, because the frozen fruit pieces get stuck or chunks of fruit or protein powder won’t blend entirely. While this blender wasn’t magically transformed into some sort of high-powered machine (after all, it was old to start with), I did notice that I was able to blend my smoothie in one go, rather than turning it off to mix everything and then turning it back on.

I’d definitely call this wacky hack a success! I’ll be keeping this old blender after all.
