Klean-Strip® Green™ Muriatic Acid, 1 Gallon

Muriatic Acid is mainly used to clean swimming pools however it can be used to clean many things. It is very effective at cleaning toilet bowls and sinks. Very easy to use but probably should wear gloves. Doesn't have much of a smell on its own but when mixed with water it does have an acidy smell and produces a gas. Good quality and great value. Highly Recommended.

cleaned my 65 year old toilets like new, I took all the water out with a cup, then used a small towel to get the rest out, keep doing this until all water is out. Then I poured the acid in right out of the jug, probably about 1/4 of the jug. Then I used a red scrubby pad to clean around the bottom rim (dipping it into the acid). USE CHEMICAL RESISTANT GLOVES, I already had some. Then I waited 30 minutes, Then I neutralized the acid using baking soda. (very slowly, because it will erupt. The reason you want to do this is so it wont damage your pipes. keep adding the baking soda until it stops fizzing. (this process takes awhile). This product had very low fumes, I only choked twice, lol. Then I used a five gallon bucket to manually flush the toilet, I did this 3 times to make sure all the acid was flushed away. ( I have cast iron drain pipes). Very happy with the results, I just hope my cast iron is happy too, lol. Almost no smell at all from the acid, very low fume, also before I started I used a tiny screwdriver to stick in the holes of the bottom of the rim, (about 10 of them). This will help your toilet flush way better! The reason I did this was because I had a huge uric deposit in bottom of toilet (it was like a brown concrete slab). I watched a 1000 videos on , Youtube, then I did it the way I thought was best.

What more can I say? Good price and Prime delivery. The secret to a clean pool is keeping the chemistry right, which requires occasional acid addition in my part of the world. This and baking soda will keep PH level correct.

I used this to clean the salt cell for my pool. Fantastic product! Works as directed.

Great cleaning product

I have old pipes in one of my houses with a bell trap that will collect organic matter. This stuff ate through it like a pack of goats on an overgrown pasture. It is very corrosive/caustic to the skin, and definitely wear the appropriate PPE (I didn't because I am a cowboy like that) AND have air circulating. It will smell like rotten eggs, so definitely don't plan on hosting a dinner party that day. I let mine work for about an hour, and the shower drains like a champ.

I bought muriatic acid to help with the ph in the pool. It works great. I put about a third of the liquid wait about 15 minutes and the ph is lowered. It helps to keep my pool water clear.

This stuff worked extremely well to make fast again a slow drain I had been battling for weeks. Rounds and rounds of Drano and electric drain snaking, and yet still the bathroom sink drained very slowly. Then I realized the problem wasn't an organic blockage in the pipes that would be amenable to Drano, but likely a hard water constriction caused by 10 years of hard water deposits on the interior of the PVC pipe.I did some research on hard water dissolving substances and learned that hydrochloric acid is highly effective but on the dangerous side, and that muriatic acid can be just as effective but with less risk involved.What I did was first prepare the pipe's hard water to be more easily dissolved with an electric kettleful of boiling water, then poured about one cup of this muriatic acid diluted in about three cups of water down the drain, then waited 30 minutes, then rinsed with another kettleful of boiling water. The drain is now lightning fast again!
