How to Remove Grout Sealer Stains

Grout should be sealed to prevent staining.

Sealing your grout is a great way to keep the grout from staining or discoloring. But it is nearly impossible to keep the sealer just on the grout joints as you apply it. If the sealer has gotten onto a nonporous tile and dried there, it can form a stain. This stain may be sticky or tacky if it is still fresh, or it may leave a dried film on the tile. Depending on the age of the stain, one of two methods can remove it.

Things You'll Need

• Additional sealer
• Foam paintbrush
• Lint-free cloth
• Tile cleaner
• Sealant stripper

Instructions

1. Paint the stain with more of the grout sealer. Sealer can frequently emulsify itself, particularly if it is not too old. Allow the new sealer to penetrate the old for up to one hour, then wipe it up with a lint-free cloth.

2. Clean the tiles well to remove the new sealer as well as any of the old that has emulsified and come up. Allow the tiles to dry completely.

3. Apply a sealant stripper to the tiles with a foam paintbrush. Take care not to get the stripper onto the grout joints, because this will remove the sealant from the grout as well, necessitating the resealing of the grout.

   Rinse the sealant stripper from the tiles with warm water and wipe the tiles down with a lint-free cloth to remove the stripper and the remaining sealer.
