If you’re trying to find a good grout cleaner, there are some types of cleaners that you should avoid using. For one, avoid using an excessive amount of bleach or a high concentration of bleach when you are cleaning tile and grout. You never want to use more than 10% concentration of bleach to water. Some sites advocate using 1 to 4 ratio, but that is just way too high, and it is likely that you are going to damage your grout in the long run, and it will also be more hazardous for your health to use this high concentration.
Another thing that you should avoid using are cleaners that are super weak. Vinegar might work as a disinfectant, but it is not that great in cleaning tile and grout. If you mix it with baking soda, it does work a little bit better, but by itself, it should not be used. There are some cleaners that worked really well. The best grout cleaner will contain a little bit of bleach, or at least an oxidizing agent that helps to break up and remove stains. The hardest types of stains to remove on grout are those that are caused by mildew. What I can recommend for mildew stain removal is called X – 14. This cleaner is made by the same company that makes WD-40. I don’t know what it contains, but it does an amazing job as a grout cleaner. If you want to use it to clean grout, all you have to do is simply spray it on and then wait. You come back after about 30 minute after you sprayed the bleach and the wipe it dry. Most of the time, the mildew stain is also gone. This is a great way to help brighten your tile grout and get rid of tough mildew stains. A lot of people who have used this product have also recommended that you use it in an area of your home that is well ventilated. Make sure that you have fans running, or that you have your windows open so that you do not inhale too much of this product.
