Rather than using a toothbrush, Tom recommends using a cleaning brush with stronger bristles. They sell specialty grout cleaning brushes at most home centers in the tile aisle. The one Tom used in the video is manufactured by QEP. If the stains are really deep in the grout, Tom recommends using a grout removal tool and lightly scraping it against the grout to remove the layer of grout that’s been stained. Do this cautiously. The grout removal tool Tom used in the video is also manufactured by QEP. Once the grout is clean, Tom suggests that sealing the grout once per year will prevent it from staining again. Tom used a TileLab Grout Sealer, which is manufactured by Custom Building Products and can be found at The Home Depot. Shop Flooring Tools & Materials at The Home Depot
