How to Make the Paste
Mix the ingredients: Combine 3 parts baking soda with 1 part standard 3% hydrogen peroxide in a small bowl.Add soap: Stir in a small squirt (about 1 teaspoon) of liquid dish soap to help cut through tough grease.Check the consistency:
Apply the mixture: Spread the paste directly onto your tiles and grout lines using a stiff-bristled brush or an old toothbrush.Scrub and let sit: Work the paste into the crevices using circular motions, then let it sit on the tiles for 10 to 15 minutes.Rinse thoroughly: Wipe away the paste with a damp cloth or sponge, then rinse the area well with clean water to prevent a baking soda haze.

Important TipsCaution for stone: Avoid using hydrogen peroxide on natural stone tiles (like marble) or colored grout, as it can cause etching or fading.
