Has anyone used it for removing calcium stains?

It works great on algae on a concrete pool, but I haven't had a lot of luck with calcium deposits (or rust for that matter).

YES, I used it to remove calcium stains. It worked great for me. Take extra care so that the surface does not scratch.

Calcium stains occur over time. There is no quick fix for them, and if you plan to try this on tile you run the risk of damaging your tile. It does however prove helpful on stains on the pool floor and those left by algae. We bought this as a replacement head...have always used this to take care of the occasional rust spot that came with someone losing a hairpin, or a black spot left by a leaf. Just as presented, it is an algae brush not a calcium build-up brush.

I would try MAAS. It removes stains and polishes without any damage. I have tried other suggested products and concoctions and this is the only one that I feel safe using on my precious metals. It is amazing!

I haven't tried it for blood stains--I use Shout with good results. Basic H is an excellent cleaner, however.

Yes it does remove rust stains. We have very hard well water and White Brite works great in our laundry.

Yes, I have. I pop it in with a load of towels and let it air dry. This takes care of any outside staining - they clean up beautifully!!

I'm not an expert in this subject by any means so take the answer with a grain of salt (no pun intended). An RO system should remove calcium as it does other bound molecules (there is very little free calcium floating in water). If you have water with very high concentrations of Ca, you may have to change the filters more often. Pretreating the water with a descaling filter might help with this but you would have another filter to change so it might be just as easy to change the filters on your RO more frequently. Good luck. Hope this helped

I found hard lime or what ever stains on my sink came off easily with this. It took the stain color away but left some roughness, but after using it several times it took the roughness away also. It also took white water stain off of my black floor tile ( ceramic).

The sealer will not remove stains, no. Use StoneTech Professional Oil Stain Remover - 3 oz to remove any stains. I can't promise it'll remove everything, of course, but it has worked wonders for me.

I tried it on the calcium ring around my pool. It was much slower to work than Muriatic acid and required more scrubbing. I'm going to try ascorbic acid next as KT suggested.

We had great luck with this. Follow the directions and yes it will remove the stains.

I live in an area where water is very hard. The filter doesn't remove the calcium. I can see that while boiling the filtered water; have to clean the boiler every day if I don't want to have any sediment in my tea. I find the Berkey filter more effective.

It works great removing white water spots from my black porcelain sink. If your stains are not set deep into the finish it may work for you. But if you think stains are deep set it may not work. It's a paste with micro scrubbing grains in it that scrub without scratching the surface and leaves my black sink looking polished. Hope this was helpful.

I did not, but I had used a home carpet cleaner prior. At first, it seemed that the Urine Eliminator worked extremely well. Unfortunately, the spots did come back. Not pleased!

Use vinegar to get the calcium buildup off! Don't use toothpaste, it's abrasive.

The packaging doesn't list calcium as something that it removes and I haven't done any testing of the water to see. Sorry!

From what I read it doesn't absorb the calcium salts that tooth enamel is made of so it shouldn't. I only use it for 5 days at a time . It does a fabulous job of whitening. Not unnatural chiclet whitening but a noticeable difference.

Try it. It removed dark stains from my tub. After application it works best if left in place for an hour before rinsing.
