You haven’t fully explored the cleaning power of baking soda until you’ve seen how great it works on dirty grout. Mix a thick paste of three parts baking soda to one part water, and spread generously between tiles. Scrub with whatever’s handy—but for truly easy going, grab your Quickly Clean Glove! The extra abrasion makes the job go twice as fast. For best results, work on small sections at a time, then rinse with clean water and dry with a towel to keep tiles free of spots.
