Toothpaste Removes Dishwasher Hard Water Soap Scum

We have hard water. Like the hardest water ever.

We’ve had a new well since the fall and new well water is a bit less hard.  When we had the old well, I was always amazed at how dirty looking the dishes are coming out of the dishwasher. They say that they changed the law and the dishwasher-soap-making companies had to change their formulas to comply with some new regulations. These new formulas combined with my hard water equals the grossest dishes, especially when it comes to glass and Pyrex.   I decided to take on my de-soap-scumming project before I put my still-gross-looking “clean” dishes away. I used toothpaste and a sponge. I’ll describe the process in pictures.

I even had scummy yuck on the pot.


These are some scummy pans. I even had that scum on the outside of the crockpot crock.

My daughter insisted that I take her picture, too.
Toothpaste is the key. This is Vanilla Mint toothpaste that I bought cheap a while back. I didn’t like the taste, so I earmarked it for this project.
After cleaning, my pot actually reflects.
Pyrex loaf pan before…
Here are my now actually clean dishes drip drying on some dishtowels.

Also, you may notice that all these pictures are closeups. Yes, my kitchen is that ugly.

    Hi Laura, I wanted to let you know that vinegar will get rid of half water stains as well. God Bless Janice

      Thanks for stopping by, Janice.
      I had tried vinegar a bunch of times to get that scum off, but it didn’t work for me.
