Sodium Bisulfate (Spa Down / Dry Acid) stains!?
« on: September 01, 2022, 07:01:08 pm »
Hey all, it seems some Sodium Bisulfate / Spa Down / Dry Acid spilled and stained our tile grout and our concrete.

Is there any way to get that out? Fix it? Or are we just F*cked?

Thanks in advance!

The acid actually probably 'cleaned' that area of concrete instead of staining it actually....Acid can be used in lighter concentration to clean hard water/rust/iron/etc. stains from concrete walkways, patios, etc
