Hydrogen Peroxide for Cleaning Grout
Yes, you can use hydrogen peroxide to clean grout when used properly.
Solution Strength: Most household hydrogen peroxide is at a 3% concentration, which is typically safe to use on grout.
Testing First: Always test a small, hidden area to ensure there is no adverse effect on the grout color or texture.
Application: Apply the hydrogen peroxide directly onto the grout. For stubborn stains, you can spray it over the area and let it sit for a few minutes to allow the solution to work on the stains.
Scrubbing: After letting it sit, use a soft brush or an old toothbrush to scrub the grout. The gentle scrubbing helps lift embedded dirt and stains.
Rinsing: Rinse the area thoroughly with water after scrubbing. This step is important to remove any residual hydrogen peroxide and dislodged dirt.
Safety Measures: Wear gloves if you have sensitive skin, and avoid mixing hydrogen peroxide with other cleaning chemicals to prevent any undesired chemical reactions.
Maintenance Tip: For regular upkeep, use water and a mild cleaning solution on grout, and save hydrogen peroxide for periodic deep cleaning sessions.
