best way to clean white grout
Cleaning Grout on Floor Tiles. The grout on your kitchen tile floor might get stained and dirty from people walking on it and food spills. The best way to clean the gunk that gets stuck in grout is with a mild abrasive and some elbow grease.This is probably not the time for using a mop, although a long handled brush can be used if you canât physically get down on your hands and knees to do the job. For those tough areas mix peroxide with a little baking soda to make a paste, use an old toothbrush to scrub the area. 2  You can let the mix sit on the grout stain a few minutes, scrub again and rinse. 3  Rinsing is generally easier in the shower area because the water is there already.
