Hydrochloric Acid 37% Solution, ACS Reagent Grade-1 Gallon

Good price on concentrated HCl acid. I can't measure the exact concentration, but this stuff is clearly very high strength.

Good for cast iron pipe make sure to wear proper gear while handling this item keep away from skin an make sure to use in a very well ventilated area

I use it for clogged toilet. I put 200ml in the tolit and wait 24 hours. The clogged problem is gone. Very useful item for clogged toilet.

I loved it and the results are amazing

Real deal

This acid is scary strong and demands full respect and full PPE. Acid vapors wafted off when I removed the cap. I bought this to dissolve rocks, but discovered they had a siliceous cement. It will decompose limestone or other calcareous rocks rapidly.

Works great to make 16 gallons of household bleach 👍🏼

the acid was fine - but be careful - this as strong as Hydrochloric acid comes - superconcentrated My problem is you have to be careful when you pour it - it wants to run down the side of the plastic jug. Then you need to use a bunch of baking soda to neutralize it use full PPE !!
