Tile makes kitchens and bathrooms look nice, but dirty grout lines aren’t a great look. Because grout is naturally porous, it acts like a sponge for dirt, soap scum, and cooking grease. Over time, it can begin to look stained and discolored.
Great news! Cleaning tile grout doesn’t take harsh chemicals or special equipment. With a few household items and a little work, you can get rid of stains and make your tile look clean again.
What you need
Before getting started, find these supplies:
- Baking soda
- Hydrogen peroxide (3%) or mild dish soap
- Warm water
- Stiff-bristle grout brush (or an old toothbrush)
- Microfiber cloths or clean rags
- Spray bottle
Step 1: Clear the surface
Start by sweeping or wiping down the tiled surface to remove loose dust, hair, and dirt. Your tile needs to be cleared so your cleaning paste can work directly on the grout without getting clogged by any loose dirt.
Step 2: Mix your cleaning paste
For standard discolored grout, a paste of baking soda and hydrogen peroxide works well. Combine two parts baking soda with one part hydrogen peroxide in a small bowl until it forms a thick and spreadable consistency. Hydrogen peroxide acts as a color-safe bleaching agent while baking soda provides the abrasive grit needed to break up dirt.
Important note: If you’re cleaning natural stone tiles like marble or slate, don’t use acidic solutions. Use baking soda, water, and dish soap to protect the stone from etching.
Step 3: Apply and let it sit
Spread the paste along the grout lines using a spoon or brush. Then let the mixture sit for 10 to 15 minutes. This time gives the hydrogen peroxide and baking soda time to penetrate into the pores of the grout and dissolve built-up grime.
Step 4: Scrub the grout lines
Take your stiff-bristle brush and scrub along the grout lines using small and circular motions. Work in manageable sections so the paste stays wet while you scrub. Avoid using metal wire brushes, since these can chip tiles or gouge out the grout.
Step 5: Rinse and wipe dry
After scrubbing each section, use a damp cloth and a bowl of clean water to wipe away the residue. Rinse your cloth frequently to avoid spreading dirty paste back over the floor or wall. Once the surface is clear, dry with a clean towel to inspect your progress.
Keeping grout clean for longer
Once your grout is clean and completely dry (usually 24 hours later), apply a grout sealer. A good sealer creates a barrier that prevents moisture, oils, and dirt from penetrating the grout again, so future cleanings are faster.
