This video from the Home Repair Tutor shows you how to make a neat little power brush to get deep into your grout lines. With more and more people putting tile in their homes in Tampa FL we would agree that this is one of the best ways to clean grout. Although, we wouldn't recommend using this on large jobs it looks great for those irritating grout lines that always seem to get dirty in the same place repeatedly. Keep in mind that any abrasive brush used to clean tile will wear down your grout if it is done too often. The Oxy Clean solution he mentions in the video can be made with any oxygen bleach and we agree that is one of the best homemade solutions for cleaning tough grout. Just make sure to let it sit on the grout for a few minutes before scrubbing. If you have a large area to be cleaned we would recommend using a professional tile and grout cleaner like Chem-Dry of Tampa FL.
