BioGuard's new formula is 10 times thicker than its popular predecessor making application easier by adhering to your sponge, brush, pool and spa surfaces easier. Sometimes stains occur along the water line because oil accumulates there, holding dissolved minerals in contact with the surface. This new and improved product is a heavy-duty, non-abrasive surface cleaner that removes scale and hard water deposits along the water line.

Twice as fast at penetrating grime and scale Our Resident Chemical Expert says: BioGuard Off the Wall removes scale and hard water deposits that may build up on your water line during the summer. I use to get the black mold that grows below my top rails during the winter. You can also use it to take off the black gook (it's a botanical buildup, by the way) that builds in your skimmer all summer. Kind of like tar (or sap) if you touch it, but wipes off easily when you use Off the Wall. It can be used for hot tubs as well. Remember to rinse the product off surfaces when you're done. It is compatible with pool or spa water.
