Cleaning grout is something that you cannot just do with a regular brush. You also can’t use sharp objects to do this job as it will break the grout. The thing that you need to get is a grout cleaning brush. Not only will this brush allow you to scrub the grout between tiles, but it also does not damage the tiles or flooring. This is a win-win! The brushes themselves aren’t very expensive and are pretty easy to find.
Using a grout brush can brighten the room simply from cleaning built-up dirt and mildew from the floor, especially in a bathroom. It also clears the air up as the dirt is no longer present. This is important if you have pets or track a lot of dirt in, or in a shower room where the floor is already slick. Having the grout clean is important.
