Work methodically from the top of the shower walls down to the floor. Pay close attention to corners, the lower rows of tile where water pools, and horizontal surfaces near the tub ledge or shower floor. These areas typically accumulate the heaviest buildup of soap residue and mineral deposits.

Let the Solution Sit

Leave the applied paste undisturbed for at least fifteen to twenty minutes. This waiting period allows the mixture to penetrate the porous surface of the grout and break down embedded oils and discoloration.

Work in small sections from top to bottom. For stubborn stains that do not come away easily, apply a little extra paste directly to the spot and scrub again with slightly more pressure. Be careful not to scrub so hard that you chip the edges of the tiles or damage the surface of the mortar.

Rinse Thoroughly
