GROUT CLEANING

480742343 shower doorI find getting soiled grout to look good again is a chore that confounds many homeowners, especially if stains have been left untreated for a long time. But with the right product, grout can be cleaned well enough to sparkle like new.

Start with the mildest solution and then work your way up to stronger stuff if stains are stubborn. For example, some people swear by plain old vinegar or baking soda to clean grout. If using vinegar, dilute with an equal part of water. Baking soda can be mixed with a small amount of water to make a paste. Then spray or dab on a short length of grout and scrub with a stiff brush. Avoid metal brushes, as they can erode grout. An old toothbrush is generally not stiff enough. Use a small circular motion for best results. Rinse well with water and mop or sponge dry.

If after testing a small section, the grime remains, consider the following options, always remembering to use good ventilation and keep all cleaning products well labeled and out of the reach of children. Never mix cleaning products, as the combined chemicals can give off harmful gases.

  • Everyday household cleaners like Mr. Clean, Lysol or Spic ‘n’ Span can work well on grout, using the above technique.
  • Powdered oxygen bleach is nontoxic, doesn’t give off harmful fumes, and is safe on colored fabrics and grout alike. Stain molecules are literally broken into pieces by the oxygen ions, which makes them easy to rinse away. Mix oxygen bleach with water as directed and apply to dry grout so it soaks in deeply. Let sit for at 15-30 minutes, then scrub with a stiff brush, applying more solution to each section as you scrub. Wipe clean with fresh water. To keep grout looking good after the initial deep cleaning, use oxygen bleach in the cleaning water each time you wipe or mop the tile, and let sit for 30 minutes without rinsing. Then rinse with fresh water.
  • Hydrogen peroxide sprayed, mopped or sponged on grout can be an effective stain remover. For stubborn stains make a paste of hydrogen peroxide and baking soda and rub with a sponge or brush. Wear gloves and avoid getting on clothes.
  • A solution of half bleach and half water can be sprayed on shower grout at night after everyone is in bed and all items have been removed from the shower. Rinse off in the morning. Again, use adequate ventilation when applying bleach, and never mix bleach with other cleaners.
  • Some homeowners get great results on grout by using scrubbers that are powered by rechargeable batteries and come with different attachments. Available for around $30 retail, they can be a small but worthwhile investment.
  • Steam cleaners can also be effective on grout.
