The best way to clean grout depends on how bad the staining, discoloration and mildew problems are. In severe cases the condition of the grout is so bad that the only option is to remove the existing grout from the tiles and grout them again. |
Even if your grout was sealed at one point, the sealer can wear off over time. Grout should be cleaned and resealed every other year or so to keep it looking great. If it is not properly sealed dirt, grime and water can easily get trapped in the tiny holes in the surface of the grout. This leads to discoloration and staining problems.Unless you have taken the time and energy to invest in a grout sealer, you will find that the grout in your bathroom will begin to accumulate dirt and it will stain more easily over time.
Alternatives for Cleaning a Grout
Detergent - Cleaning grout with a mild detergent and a small scrub brush is the most basic way to clean grout and works for grout that is just slightly dirty. Mix mild detergent with water and use a scrub brush on the grouted areas. Work on one small area at a time and rinse with warm water before moving on to the next.
Chlorine and Water - Use bleach with caution since it can discolor tile and grout. Mix 1 part chlorine bleach with 4 parts water. Wipe or spray it on the affected area and lets sit for a few minutes. Rinse with warm water.
Baking Soda and Water - Mix a small amount of baking soda and white vinegar and then scrub the grout lines using a toothbrush or small brush. Work in small sections and rinse each area with warm water before moving on to the next section.
Hydrogen Peroxide and Water - Only use this on method on white grout since it can discolor colored grouts and be sure to test a small, hidden area first. Mix water and hydrogen peroxide in a 1:1 ration. Apply to grout lines and let it sit for 15 minutes, then rinse with warm water.
Vinegar - If you are trying to restore your grout to a gleaming white once again, then vinegar might be just what you need. Pour the desired amount into a spray bottle and combine with a little water, but not too much or else it will dilute the vinegar and make it less effective. Mix the vinegar and water solution by shaking the spray bottle and then spray it directly onto the grout. Leave the vinegar and water solution to work and then return in a few minutes, or longer if the grout is badly stained.
Wipe the vinegar and water residue away and then pat dry. For extra protection, use grout sealer to seal the grout and prevent any further build of stains in future. But before you seal the grout, make sure that the tile and grout are completely dry, otherwise the grout sealer will not be absorbed into the grout and work as effectively.
Professional Steam Cleaning for Grout
If none of the above options work you may need to consider getting quote from a professional cleaner for getting your grout steam cleaned. This is a good option if none of the other methods listed here work to remove the stains from your grout or if you have a large area of grout to clean. Most professional grout cleaners will be able to tell you upfront if steam cleaning the grout will remove the stains or not and should give a free price quote.
