How to Clean Grout — Stains and All
If your grout is grossing you out, this deep-cleaning method will help it look new again
Tile — whether it’s used as flooring, in the kitchen or in the bathroom and shower — has one great downfall: grout. Since grout is porous in nature, unsealed tile grout absorbs all kinds of stains, from mildew to coffee and everything in between. To say it’s a headache to keep grout clean is an understatement.
Note: Be wary of using too much lemon juice with marble, since it can etch or damage the stone if left on too long. Hydrogen peroxide can be a safe alternative.

How to Clean Grout
What you’ll need:
- Oxygenated bleach (I use OxiClean to clean tile grout)
- Warm water
- Coarse scrub brush (like an old toothbrush)
- Towel
- Lemon
- Grout sealer
1. Clean the surface thoroughly, removing any surface residue or debris. Let the grout dry fully.
2. Dissolve 2 tablespoons of oxygenated bleach in 2 cups of warm water. Wet the grout brush in the mixture and apply it to the grout. Let it soak in, then scrub the grout in a circular motion, which will loosen the stain more effectively than a front-and-back motion. If needed, dip the wet brush into the oxygenated bleach to make a paste. Wipe clean, then let dry.
Tip: To clean extra-dark grout stains, squeeze lemon juice onto the stain, let it soak in, then scrub, wipe clean and let the grout dry. Use lemon juice sparingly, since it can damage some tile finishes.

3. Spray the grout lines between tiles with an eco-friendly cleaning solution and wipe clean. Let the grout dry fully before making a final decision on whether your hard work paid off — damp grout looks darker than dry grout.
4. Apply grout sealer after the grout has fully dried to avoid any future stained grout. Be sure to reapply it each year.

This coffee stain, on the other hand, took a bit more elbow grease, a longer soaking time and a few repeated attempts before it was sparkling clean again.
