Start cleanup within fifteen minutes after grouting to prevent grout haze from bonding to the tile surface.

When working with large format tile, begin by mixing clean, cool water in a bucket and keep a second bucket for rinse water so you always have fresh liquid for the sponge. Use a soft, nonabrasive grout sponge dampened but not dripping and make overlapping passes across each tile face using light pressure to avoid drawing grout out of joints. Change the rinse water frequently and wring the sponge thoroughly so you are always wiping with clean water instead of smearing residue; a dirty sponge is the main cause of streaks. For stubborn haze after the first pass, allow tiles to dry fully and then buff the residue with a dry microfiber cloth or a white nylon pad using circular motions to avoid scratching. If haze still remains, prepare a manufacturer-approved grout haze remover or a diluted mixture of ph neutral cleaner and water, test it on a small area first, apply sparingly, agitate gently with a soft cloth, and rinse thoroughly with clean water. Always follow tile and grout manufacturer instructions for chemical use, wear protective gloves and eye protection when handling cleaners, and work in sections no larger than you can comfortably handle to keep water control consistent.

Three common problems are scrubbing too hard and scratching glazed or polished tiles, leaving dirty rinse water which causes streaking, and waiting too long so the haze cures and becomes difficult to remove. Scratching is prevented by using nonabrasive sponges and white nylon pads only and by reducing pressure while cleaning. To avoid streaking change rinse water often, wring sponges well, and use a separate clean bucket for final rinses. If haze cures before cleanup, wait until tiles are fully dry then use a cementitious haze remover or an appropriate manufacturer-approved product applied in small areas with gentle agitation and follow with thorough rinsing.
