Your bathroom is most likely the most prominent place for mold to grow in the grout between the tiles, but it can grow anywhere. If there is a place in your home where the tile and grout are constantly getting wet, it will be more susceptible to mold. There are a number of methods and chemical solutions that can be used to get rid of mold that has grown in the pores of your grout.

Spray the grout with the mixture and let it sit for at least 2 minutes to soak into the porous material. Wearing your gloves and safety glasses, begin scrubbing the grout with the grout brush.

Vinegar is the best natural, non-toxic solution to use to remove stains or mold from your grout.

Once the substance has had time to soak into the porous grout, scrub the designated area with a grout brush. We advice you to do one section at a time and while you are scrubbing one section, another can be soaking in the vinegar solution. After you scrub each section, spray the entire area once more with vinegar and let it sit for another 30 minutes before spraying it down or mopping it up with water. It may not leave the best smell in your house but it will get the job done and remove the mold that has formed in your tile grout.
