Cleaning with muriatic acid

[Brucet99]

I need to remove uric acid scale from my Toto 1.26gpf toilets. Pool acid available nearby is 14.5% hydrochloric.

Should I plunge the toilet to remove most water, then pour in acid to normal water height so that acid gets into all passages that would have scale build up, or simply pour into filled bowl?

What dilution, if any is best? Pouring a gallon of acid into normal water level should result in about 1:1 dilution. I guess that plunging first would result in maybe three times that strength.

Ive done it but highly dont/ wont recomend it. had a house cleanner use a pumice I cringed worked fine and no damage that I saw I dont recomend it per say but at least its safe.
Heck no a gallon of pool acid down A toilet to me is wackey ? I guess I have too much respect for safety (though I though I was a bit of a risk taker) also the acid steam or fume takes is horrible to breath just that fume in bathroom probebly damaging

Pull the toilet and clean it. There are bruses and all types of things that can be used that will flex around the curves and get it perfectly clean.

Never use muriatic acid inside a home. The fumes can overwhelm you and burn your throat and lungs.
Get ZEP acid bowl cleaner. Home Depot has it. With a dry bowl above the water line, coat the porcelain with the bowl cleaner. Let it sit for several hours or overnight. Brush the bowl and flush. May need a second treatment. Never use a pumice stone. All it does is scratch the finish leaving it rough and causes the surface to hold on to additional staining.
If it is that bad, just replace the toilet.

The stone worked you can always throw toilet away later . I concider it last resort and was pretty pissed off that house cleanner used it but its 22 years old and works and looks good its been a year since it was stoned , had a pretty good ring around it at the water line only

Pumice won't damage the toilet. You would think that it would, but it actually won't.

I'd drain all the water out of the bowl and fill it with white vinegar. Let it sit for an afternoon, and then go in with pumice stone or a scotch bright pad and scrub the living daylights out of it.

Turn the toilet off at the base and flush it. Then take the tank lid off and pour the vinegar down the overflow tube in the tank. This will allow the vinegar to go through the channels of the bowl.

Muriatic acid is a great cleaner and will make a toilet look brand new, but it is very toxic and can cause great harm if it gets in your eyes or on your skin.

I strongly suggest not using muriatic acid

I used muriatic acid many times on my home office Toto Drake. Not recommended due to hazards...ok results that don't last and super dangerous. Tried pumice for poor results. Happily replaced with new toilet.

I decided to use vinegar to clean the holes under the toilet rim. When getting the vinegar from the store I noticed that pickling vinegar has 7% acetic acid. 2% more than regular white 5% vinegar.

Vinegar comes in different strengths up to 47% for grass killing.
