Questions about the use of muriatic acid (HCL)

[Aquattro]

Using it 10:1 is fine. It may corode metal parts if left way too long, probably not a concern. Well ventilated area is smart. To dispose of the water/acid mix, pour a box of baking soda into it to neutralize.

Don't spill it on concrete, it will etch it. Wear glasses and gloves. Keep away from small children. Always add acid to water, not the other way around.
