Removing Stains Above Toilet Water Line?

A stain above the water line in a toilet.
To remove stains above the water line in a toilet there are a couple of good methods to try. Using a pumice stone may work. Also, shut off the water and fill the bowl to just below the rim and add a cleaner or vinegar, soak, and then scrub. This is a page about removing stains above the toilet water line.

Please help! I moved into a townhouse and both toilets have greenish stains above the water line where the water flows (in lines down the bowl to the water line.) I can only assume these are from over- use of colored "toilet tabs" and the like without regular cleaning. I am able to clean below the water line nicely, but above the water line it is horribly stained. Any suggestions? Would pumice work for these stains? Thanks!

I have the same problem when I put the blue "cleaning" tabs in my toilet,I only use them because our water has a brown residue so I have to use a pumice stone on them to remove both works ok with a lot of elbow grease but sometimes I stop the toilet up with a dirty dishtowel,shoving it in tight enough to hold water and pour pure clorox bleach in, filling your toilet to the rim on top,letting it set for 30 minutes to an hour, then remove the dish towel and wash with a toilet comes sparkling clean.(we also have very hard water so the pumice removes the ring that's always there.) make sure the kiddies nor the hubby doesn't have access to the toilet or they'll flush the dishtowel...

Turn the water off to your toilet. (valve behind your toliet on the wall.) Spray the entire inside of the empty toilet with undiluted white vinegar or C.L.R. Let stand 1 hour. Srub well with a stiff toilet brush. You may need to repeat again. When stain is gone, Slowly pour 1 gal.


cold water into the toilet bowl to rinse and turn on the toilet again. While you have the toilet empty, take a toothpick and clean out the flow holes under the rim. This will give a longer life to the fixture. Good Luck!!!

I've never used pumice for these mineral stains but a simple cheap way is to don a glove and rub the stains with 'wet and dry' sandpaper - that's the very fine black one available in hardware stores. You don't have to remove the water and with a very moderate amount of rubbing will remove these deposits without damaging the ceramic surface.


I have a feeling bleach will remove the colour but the deposits will remain and stain again quickly - I may be wrong. I 'renovated' a toilet I was thinking of replacing using 'wet and dry' sandpaper - it was the old one in a house I bought which came up like new and was able to be 'recycled' to the new bathroom.

Replace the colored toilet tabs with the bleach tabs. We have very heavy minerals in our water that leave stains and this works well to minimize the stains left.

As a service plumber for ten years I can offer this. The stains are from minerals in the water, this differs everywhere and depends much on where the supply comes from, aquafers, wells, mountain, spring etc.... Borax is natural, kills mold, removes stains and will not effect your system if it happens to be septic.


It is safe, allergy friendly and kills odors as well. give this a try. If it is especially bad let it sit for 5 minutes before scrubbing.
