Klean-Strip® Green™ Muriatic Acid, 1 Gallon

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!

Excellent product!I purchased this for removing hardware stains from calcium build up in the bottom of a toilet.A little bit of the product works wonders, I poured it in directly into the water in the bottom of the bowl, came back after letting it sit all day while I was at work and voilà, makes your porcelain throne look brand new again, without damaging it.

Does the job very well! Removes that nasty calcium deposit in the toilet bowl. Other commercial products wont do, we tried a bunch of them and wasted money. This one 5 stars for me.

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

I was amazed at how well this cleaned my seashells!! I was surprised at how vibrant they get. A must have for people who love to beach comb and have a collection of shells at home to show off.

Got this for my pool, works great and does everything it's supposed to do.

Excelente producto 👌🏽

I purchased this to use for recycling precious metals thinking it was a good deal. Something in the hidden ingredients prevents the proper reactions to occur and ruins the process.I'm sure it is good for other uses but, specifically speaking of precious metal retrieval it is a no go.
