When you’re in the grocery store there are many options for bathroom cleaners available that are specifically targeted for grout. These cleaners come in many different forms from sprays, foams, and even powders. This is all personal preference and what will work for you is all dependant on how set in the staining is, the location of the grout, and how regularly you clean your grout. Regularly cleaned grout can withstand simple cleaners like spray and foams that don’t require a set time to work their magic. If you’re looking at more set in staining you may find that foams and gels that have to sit for a period of time may work better. Powders can be effective with floor tilemaking it easy to scrub into a paste, let it sit, and mop with hot water to see a great effect.
