Grout is a sandy material used to seal tiles. Porous texture of the material can trap dirt and stains. When exposed to water, grout provides an ideal environment for mold to grow. Regular cleaning is not always sufficient to remove stains or mildew. Hydrogen peroxide can kill mold and can whiten grout without emitting noxious fumes. Do not scrub hard is necessary, so you can improve the appearance of your grout with little effort.
Instructions
• Fill a spray bottle with oxygenated water.
• Spray Grout with enough peroxide to saturate evenly. Allow the liquid to rest for 30 minutes. If the peroxide dries before that time, spray the area again to keep it saturated.
• Scrub Grout with a brush or old toothbrush. Use rubber gloves to protect hands during cleaning.
• Fill a bucket with warm water and immerse a cloth or mop in the water. Drain and clean or mop the nozzle to remove any peroxide. If cleaning shower tiles, fill a glass with water and pour into the sides to rinse the peroxide.
• Allow grout to dry air.
Tips and warnings
- Grout will appear darker until completely dry.
- Do not use hydrogen peroxide to clean dark or colored grout. Hydrogen peroxide can fade color.
