Nifty Grout Cleaning Guide

Cleaning your grout sounds about as appetizing as filing your taxes or paying a speeding ticket. But, like so many adult responsibilities, it must be done.


What is grout? It’s the material used between tiles to fill in spaces and give strength to tile. It comes in four types: sanded, un-sanded, acrylic latex and epoxy. It can come in a variety of colors. If it’s not properly sealed – that is, if a water-repelling sealant isn’t applied – it can become vulnerable to wear and tear.


Bathroom tiles are pretty durable and are made to last a long time. However – dirty, grimy, cracked and stained grout can make your bathroom look old way before it’s time. Things like hard water and debris can collect in your grout and become unsightly. Here are five tips to help keep your bathroom sparkling white.

    Make sure all your hard work doesn’t go down the drain by applying a sealant. That will make it harder for stains to show the next time.
  1. 1.Mix it up

    Stir together ¼ cup baking soda, ¼ cup salt and ¼ cup of water. Spread the mixture over the grout, and scrub then wash clean after a few minutes. Baking soda isn’t the only household supply you can use to clean your grout. There are a variety of things you probably have in your home that you can use to clean your grout, including vinegar and lemons. Mix a paste of lemon juice and baking soda in equal parts. Spread, then scrub and rinse clean. Or make a mix of ¼ cup salt, ¼ cup baking soda and ¼ cup vinegar. Make a mix of ½ cup baking soda, 1/3 cup ammonia and ¼ cup white vinegar to seven cups of water to make a cleaner for your grout and tiles.

  2. 2.Bleach

    Bleach can help get rid of any mold and mildew that may be growing in your grout. The wet environment of a bathroom is a great environment for yucky growths and they can pose a big health hazard. According to the National Institute of Environmental health sciences, mold loves dark, humid and musty environments. It can take hold in your home and produce allergens that can make you sick. Scrub the grout with a mixture of one part bleach and five parts water.

  3. 3.Repair

    If your grout is very badly worn, doing spot repair is an easy do-it-yourself job. Purchase the grout at a home improvement store, but make sure it matches the grout already in your house. Clean the area needing repair with a mixture of vinegar and water, mix up the grout and apply with a grout float. Then, remove the excess grout with a squeegee or grout sponge and let the area dry completely.

  4. 4.Grout Sealant

    Make sure all your hard work doesn’t go down the drain by applying a sealant. That will make it harder for stains to show the next time. Before applying the sealant, make sure the grout and tile is completely clean. Next, use the sealant that is best for the type of grout in your home. Then make sure the area you are working in is well ventilated. Finally, use a sponge or brush to apply the sealant.

  5. 5.Leave It To The Pros

    Professional grout cleaners use a mix of hot steam, detergents, water and vacuum extraction to get grout good as new. These service professionals know what they are doing and offer great time saving benefits.
