Cleaning the Grout

If a stubborn stain emerges in your grout, follow the same steps described in the procedure above to gently work the stain out. If a situation arises in which the stain cannot be removed, it might be necessary to replace that particular area of grout. Grout can be removed quickly and effectively by using a small grout remover, inexpensively bought at any home improvement retailer. Work the stained section of grout until you are beneath the stained area and clean grout is present.

You are now left with an indentation in the grout that needs to be filled. Bring a grout sample, if possible, to your local tile store or home improvement retailer, and try to get the closest match you can. Once you have obtained the material, pour the dry mixture into the cavity you created. If the color matches to your liking, vacuum the dry mixture out and follow directions on the box to make a small batch. Use a rubber glove and a finger to firmly apply the grout to the damaged area. Blend the mixtures in to the best of your abilities, and clean the area with a clean, damp sponge. Verify the joint composition is a match to the original grout.
