Use a commercial grout cleaner
4
Apply a dedicated grout cleaner in spray or gel form directly to grout lines. These products contain surfactants, alkaline agents, or mild acids that dissolve soap scum, grease, and mildew faster than most household mixtures. Follow the manufacturer's dwell time (usually 5-10 minutes), scrub with a stiff brush, and rinse thoroughly.
Why It Works
Commercial formulas are engineered to penetrate porous grout and break down specific stain types. Products like Zep Grout Cleaner, Black Diamond Stoneworks, or Soft Scrub with Bleach offer targeted chemistry that general-purpose cleaners lack.
Tips
- Never use acid-based cleaners on natural stone (marble, travertine, limestone, slate) as acid permanently etches and dulls these surfaces
- Always spot-test in an inconspicuous area before full application
- Wear gloves and ensure good ventilation, especially with bleach- or acid-based formulas
- Choose a pH-neutral cleaner for polished or delicate tile surfaces
