Clean Grout with Baking Soda and Peroxide

The Problem

Dark grimy grout makes clean tile look dirty. Professional cleaning costs $200-500.

The Hack

Mix 1/2 cup baking soda with 1/4 cup peroxide. Apply to grout with old toothbrush. Wait 10 min, scrub, rinse.

Why It Works

Baking soda abrades surface grime while peroxide bleaches without harsh chemicals.

Pro Tips

• Let paste sit 30 min for stubborn stains
• Add dish soap for extra power
• Seal grout after to prevent staining
• Works on floor and wall grout
