Squirt two or three drops of Dawn on a wet sponge or rag. Scrub tiles that are greasy or contain hard-to-remove stains. Rinse the rag or sponge well and wipe the tiles clean to rinse. Rinse several times until all the Dawn, grease and debris are removed.
Fill a bucket with 1 gallon of warm to hot water and add 2 tablespoons of Dawn. You can also add 2 tablespoons of Borax for a more effective cleaning solution. Use this mixture to clean the tiles with a rag, mop or sponge. Rinse well with water after cleaning.
Shine dull tiles with equal parts Dawn and Epsom salt. Dab the mixture on a sponge or rag and scrub the surface clean. Test the mixture in an inconspicuous area to be sure you don't damage the tiles in the process. Rinse well with water.
