Grout is a sandy, porous material used to seal the spaces between the tiles. Grout in a tub tends to absorb dirt and soap residue, and can promote the growth of mold and fungus in humid locations. It is possible to clean and brighten the grout without hard fumes using oxygen bleach. Oxygen bleach absorbs deep into the grout and dissolves dirt and stains without excessive washing. Clean your bath grout regularly to make it look your best.
Instructions
1 fill a spray bottle with hot water and add 2 tablespoons. of oxygen bleach. Shake the bottle to completely dissolve the oxygen bleach.
2 Spray the tile grout thoroughly with the cleaning solution. Be sure to soak grout with cleaner. Leave to soak for a maximum of 30 minutes. If the solution dries in the grout, spray again to keep it moist.
3 Rub the grout with a grout brush or old toothbrush.
4 Rinse the grout thoroughly with clean water. Use a large glass or removable showerhead to rinse the sides. Allow grout to dry thoroughly.
