How to Remove Mould and Whiten Grout Without Using Chemicals

cleaning-grout

Mould is not only unsightly; it can also become a health hazard if sufficient action isn’t taken to keep it at bay. Unfortunately, where grout is concerned this is easier said than done.
While mould can certainly hard to prevent, in most cases it can be removed from most surfaces. Grout, on the other hand, can cause no end of headaches because the mould thrives within the porous surface of the grout itself, making it next to impossible to clean without resorting to using harsh chemicals.

Grout causes a particular problem then, and not just because it is white and every minor bout of mould sticks out like a sore thumb. Grout is also easily stainable, which means cleaning it can often make the grout appear dirtier. The surface area is also particularly small, making it harder to give it the thorough clean necessary to properly remove the mould.

To remove mould from grout and keep it looking white, the following steps can be taken, none of which require harsh chemicals or bleaches.

Getting Started
Begin by equipping yourself with the following environmentally-friendly ingredients: baking soda and vinegar. These two seemingly innocent items are the bane of a mould culture’s existence.
A toothbrush (or grout brush if you have one to hand) is also needed for getting the job done properly.
A microfibre cloth can also be used during the final stage to help brighten up the grouting and keep it looking new.

Removing the Mould

  1. Spray the mould using a 50/50 solution of water and vinegar, then immediately begin scrubbing the grout with the toothbrush or grout brush. Brush in circular motions for the best results.
  2. Assess your work. If the mould is particularly stubborn and the vinegar solution is barely working, then it’s time to bring in the baking soda. Make a paste made with the baking soda and some water and spread the mixture over the grout, then scrub thoroughly into the grain with your brush.
  3. Rinse the grout with water and wipe with a microfibre cloth to help remove any staining and help whiten the grout.
  4. Repeat the above steps as necessary. Several applications and rinses may be necessary, depending on the extent of the mould.

In most cases this eco-friendly solution of vinegar, baking soda and water will suffice. For more stubborn build-ups of mould, a steam cleaner can also be used  on the grout to help completely remove all traces of the mould.
