How To Clean Dirty Grout

Ceramic tiles are a great feature to your home. They add value and look great, but the inevitable is sure to happen, and that’s when the grout turns brown or black. That discoloring is caused by dirt and mold built up over time, and it can be a pain to restore the grout back to its natural color.

Lets face it, no one enjoys getting on their hands and knees with a tooth brush to clean grout. But in order to maintain a presentable kitchen, bathroom, office, etc.  certain measures are to be taken.

Walk into any home improvement store and all the supplies you need can be found within 1-4 aisles. There are products that are more expensive than others but when it comes down to it, they all pack the same results. Below are a few methods to clean grout, give some a try and tell us how they worked for you.

  • Oxygen bleach – With oxygen bleach there is little worry about damaging your floors. The oxygen ions release the dirt and mold from the grout providing little manual effort. Let the solution sit on the grout for 10-15 minutes, once you come back wipe away the solution. There may be some additional scrubbing with a toothbrush if need be. Note: NEVER use everyday bleach for it will damage and stain your tile and grout yellow.
  • Hydrogen Peroxide – One of the more affordable methods is using H2Oor commonly known as hydrogen peroxide. Due to its oxidizing properties hydrogen peroxide is comparable to bleach without the  toxicity, so using this is sure to do the trick. Simply pour the chemical directly on the grout and let it sit for 15 minutes. Once you come back scrub and wipe up the solution and you should have dirt free grout.   A bottle of Hydrogen peroxide can be found at any corner store for ~$1.
  • Baking Soda & Vinegar – Mixing baking soda with warm water will create a paste that is suitable for lifting dirt off any surface. In this case, spread the paste on the grout and let it sit for 60 minutes, after the full 60 minutes rise the paste off. For step 2, mix water and vinegar (3 parts to 1) and scrub the mixture into the grout with a brush. The high acidity of vinegar works great for killing any left-over mold that may be caught in your grout. Lastly wash the floor with warm water and a mop. This method is the most time consuming but you should have all you need already stored somewhere in your house.
  • Store Bought Solutions – Using store bought solutions from your local home improvement store is always another method you could use. However you will be paying 3,000% more than the solutions listed above. Some seem to work very well, while other products seems to just scam you into buying the product as a quick fix. Truth is, they typically do not work well.

The sad reality with keeping your grout clean is that it is a never ending task, one clean will not keep it clean forever. There is constant maintenance that you need to keep up with. It’s a time consuming task and sometimes the results are not worth the effort. Luckily there are cleaning companies that have the equipment to remove all that dirt and mold caught between your tiles within minutes using high powered water jet machines and powerful green cleaning products that are not harmful to you, your children, pets, or your floor.

Whatever method you choose, please let us know your results below. Good Luck!
