When Grout Goes Black?

The most common reason for grout to turn black is the accumulation of mold and mildew. When grout is not sealed properly or if it is exposed to high levels of moisture, mold and mildew can grow and thrive in the porous surface of the grout. This can cause the grout to turn black and create a musty smell.

Another reason why grout goes black is the accumulation of dirt and grime. When grout is not cleaned regularly, dirt and grime can build up in the porous surface of the grout, making it appear dark and discolored. This can be particularly problematic in high-traffic areas such as kitchens and bathrooms.

Another reason why grout goes black is the use of harsh cleaning products. When harsh cleaning products such as bleach and acidic cleaners are used on grout, they can cause discoloration and blackening of the grout over time.

To prevent grout from turning black, it is important to seal the grout after installation, to clean the grout regularly and to use appropriate cleaning products for grout. It's also important to keep an eye on the moisture levels in the area where the grout is installed and to address any leaks or water damage as soon as possible.

If your grout is already black, the first step is to clean it thoroughly. A solution of water and white vinegar can be effective in removing mold and mildew, and a grout cleaning solution specifically designed for mold and mildew can also be used. After cleaning, it's important to reseal the grout.

In conclusion, grout goes black for several reasons, including the accumulation of mold and mildew, dirt and grime, and the use of harsh cleaning products. To prevent grout from turning black, it is important to seal the grout after installation, to clean the grout regularly and to use appropriate cleaning products for grout. If your grout is already black, it's important to clean it thoroughly and reseal it to prevent further discoloration. It's also important to keep an eye on the moisture levels in the area where the grout is installed and to address any leaks or water damage as soon as possible.
