Clean the grout without guessing at the surface.

Start dry

Loose grit can scratch and turn into muddy residue.

Vacuum or sweep carefully before wet cleaning, especially around entries and kitchens. Use tools that reach grout lines without damaging adjacent surfaces.

• Remove loose debris first
• Pay attention to corners and edges
• Avoid abrasive tools on uncertain finishes

Match the product

Stronger is not automatically safer or more effective.

Acidic, alkaline and solvent products can affect grout, sealers and some tile materials differently. Follow manufacturer guidance and test uncertain products discreetly.

• Never mix household cleaning chemicals
• Identify natural stone before using acid products
• Allow the surface to rinse and dry fully

Know the limitation

Cleaning cannot repair damaged grout or every colour change.

Embedded staining, failed sealers, missing grout and material damage may need repair or restoration rather than repeated cleaning. A professional assessment should explain that difference.

• Point out previous coatings or sealers
• Separate buildup from permanent discolouration
• Discuss protection only after the surface is clean
