Champion 4-Pack Acidblue Muriatic Acid for Swimming Pools & Spas, 1 Gallon Each - Low-Fume pH Stabilizer & Cleaner for Concrete & Masonry Surfaces, Clears Rust & Scale Build-Up

We have tried other brands and this company makes a great acid at a great price point. We have a chlorine free pool and this is basically the only product we have to use.

I used it to clean the hard water ring around my pool & spa. It did a good job & I like that it's not irritating to the skin. Good price too!

clear smell --safely wrap for shipping

Why did you pick this product vs others?: We've had our pool for just over 1 year and this product works great. It was recommended to us. It quickly corrects our pH levels.

Great product but it doesn’t last as long as the regular muric acid that I buy from the local pool store. This is safer and that’s why I will continue to use it. It has no toxic fumes but I still take the same precautions that I do while using any acid product.

Todo perfecto

Works great.

Exactly what we needed and delivered overnight as promised
