Swimming Pool Muriatic Acid, Gallon - Pack of 4

Sunbelt 1 Gallon Muriatic Acid. 20-degree Baume. For pH adjustment and acid washes. It effectively lowers the pH level of swimming pool water, ensuring optimal water balance. This versatile acid can also be used for etching and cleaning brick, stone, tile, concrete, and other masonry surfaces. Always start with diluted acid and test the effects in an out-of-the-way area. Add the acid to the water when diluting to avoid splattering and violent eruptions. Neutralize acid solutions with baking soda, soda ash, lime, or household ammonia solutions, followed by thorough flushing with water.
