How to remove very stubborn mineral build up inside my potpourri pot?

Did you soak over night in vinegar? Try CLR?

Have you tried soaking a paper towel in vinegar and applying it to the inside of the pot? It needs time to work and that is why I use paper towels since they stick better when wet. I just leave it on for about 4 hours while doing other things and then come back wipe it out and rinse.

Hello, Are you referring to hard water deposits? I recently used Whink and it was by far the easiest experience removing hard water stains. I used it on my hot pot— crusty bottom interior mineral build up on the inside metal base and on the plastic pouring spout and on the underside of my kitchen faucet where the aerator gets crusted and clogged. It worked effortlessly and quickly. I hope this helps!

White vinegar will dissolve the mineral build up on your pot. Let it set over night then rinse out. You may need a little scrub brush also. Repeat if it is needed. It does all the hard work for you!
