Best Grout Cleaners

When people hear the word grout, the first thing they tend to do is shudder, thinking about the amount of dirt, mold, and stains they have to clean. While the grout plays an essential role in filling the spaces between showers, floor tiles, countertops, and other surfaces, they can be a pain to clean. Those little ridges and grooves provide the perfect place for mildew, grime, and dirt.

These spaces trap dirt that leaves your grout looking grungy. Not only will it look gross, but it will also cause other substances to lurk in your house. And this is where grout cleaners come in handy.
Grout cleaners will help facelift your bathroom by giving it a clean and brilliant look. Here’s our review of the best grout cleaners on the market.

Buyers Guide

  1. How do I choose the best grout cleaner?

    Answer: It may appear that all grout cleaners have the same powerful cleaning formula, but that isn’t the case. Therefore, when choosing the best cleaner, keep the following factors in mind. First, consider the stains. Bleach is an excellent germ-killer and whitener. Thus, if your grout has too many stains, mildew, and mold, you will need a grout cleaner with a strong bleach formula. Second, think about your surface safety. Ensure you read the label before purchasing the cleaner to ensure you can use it on several surfaces before cleaning. Lastly, choose your form. Foams and sprays are easy to apply; however, they drip and run off before you get the job done. Go for thick gels as they last longer, but it may require more effort to rinse.

  2. How do I use grout cleaners?

    Answer: The best way to use grout cleaners is by following the manufactures instructions, as each cleaner comes with a different formula. You can also start by washing the tiles with a mixture of mild dish soap and warm water. Once the surface is clean, apply your choice cleaner to get the dirt out of the grout. Allow it to sit on the grout for a few minutes. Once the few minutes elapse, wipe the cleaner, and rinse the surface with warm water and dry.

  3. How do I prevent mildew from developing in my bathroom grout?

    Answer: First, open a window. This will help remove as much moisture, heat as possible, and minimize the moist conditions required to grow. Next, squeegee the tiles by drying them with a towel. Lastly, try to keep your grout sealed to help prevent it from penetrating the surface.
