Test Grout Treatment Before Cleaning the Entire Floor

The Spruce recommends considering grout type, working in sections and removing all dirty cleaner residue.

Consider the grout type and cleaner together

The Spruce distinguishes sanded, unsanded and epoxy grout, emphasizing that their condition affects how cautiously they should be scrubbed. Begin by sweeping or vacuuming the surrounding floor. A commercial cleaner should be diluted and applied as directed, while any proposed homemade method needs a hidden-area check for compatibility with the tile. Appropriate gloves and eye protection are particularly relevant when handling stronger products.

Collect the residue rather than leaving it to dry

Once a suitable cleaner has loosened grime, work the lines in small sections and wipe away dirty solution with a clean damp cloth or sponge. Rinse the cloth as needed so it does not move the same soil back across the joints. Remove excess water and allow the grout to dry. The article also discusses compatible sealing and routine moisture removal as ways to reduce future buildup instead of repeatedly relying on intensive treatment.
