Scrub with Baking Soda Paste

Make a thick paste of baking soda and water, spread it along grout lines, let it sit for 5-10 minutes, then scrub with a stiff-bristled brush and rinse clean. This is a gentle, non-toxic first approach for lightly stained grout.

Why It Works

Baking soda is a mild abrasive that physically loosens surface grime without scratching tile or degrading grout. Its alkaline pH helps dissolve grease and soap scum. Because it is non-toxic, it is safe for use around children, pets, and food-preparation areas.

Tips

• Use an old toothbrush or a dedicated grout brush for scrubbing narrow lines
• For tougher stains, let the paste sit for 15-20 minutes before scrubbing
• Rinse thoroughly afterward to avoid a white residue drying on the tile
• Do not mix baking soda with vinegar on grout -- the fizzing looks dramatic but the acid and base neutralize each other, leaving mostly salt water with less cleaning power than either ingredient alone
