Cream of tartar is one of the coolest household tools. It is really great for cleaning, but can be used in things like DIY bath bombs or face scrubs.

When I was testing and researching cream of tartar uses many years ago, I wanted to find useful things for it because I always had a little bottle sitting around.

I would it for baking, but then it would sit on the shelves and expire. You might have some sitting around too, and now you can use it for something convenient!

We have a great blog post you can check out with more details on cleaning hacks with cream of tartar.

To make it, you will need cream of tartar and water.


Add a tablespoon of cream of tartar to a small bowl, then add a very small amount of water - about ½ tsp. to start.

This mixture needs to be a paste to begin with since it will break down as you use it. If you add too much water, that’s okay, it still works great as a liquid, it just won’t have as much scrubbing power.

Dab onto the area to be cleaned, leave on for a few seconds, then wipe off.

Use under the stove area, around the dishwasher, washing machine nooks that are dirty or rusty, window seals, etc.

I use it on kitchen knives that have rust around the edges.

I also purchase cream of tartar in bulk from Amazon.

It’s non-toxic and works great! Read more science on how it works in the blog post.
