After some time, your grout can get dirty from mopping your tiled floors with brown water or from walking on your floors with dirty feet. To brighten up your grout lines, you may want to get a cleaner that’s specifically formulated for grouting. I recommend using Grout-Eez because it's a heavy-duty grout cleaner that comes with the tools you need to scrub between your tiles. The product lifts tough dirt and stains from your grout lines easily. To start, simply spray the product directly onto your grout lines. Avoid applying the cleaner to your tiles because you don’t want to waste the product. Let the solution sit between five to 10 minutes and then start scrubbing the lines with your brush. Rinse your floors with water and mop up any residue that’s left behind. The Grout-Eez has a low odor, so your kitchen won’t smell like chemicals. It’s also safe to use on any color grout, whether it's white or black. This brand also makes a heavy-duty floor cleaner and natural stone sealant.
