What is the black stuff under my carpet?

The most common reason is that remnants of glue or rubber from the old carpet have been left behind and have started to blacken over time. Sometimes water stains can form after a carpet has been shampooed. Another possibility is that mold or mildew has begun to grow on the surface, which will leave black spots behind.

If the black spots are caused by glue or rubber, you can remove them using a few simple steps: First, we recommend homeowners always put on a mask, gloves, and safety glasses before beginning any kind of cleaning process. Try to scrape off as much of the glue or rubber as possible using a scraping tool. Be careful not to damage your flooring in the process. Next, use an enzymatic cleaner to break down the remaining adhesive. This type of cleaner is available at most home improvement stores. Finally, use a wet vacuum to clean up the remaining adhesive and moisture.

Mold or Mildew Spots

If the black spots are caused by mold or mildew, you’ll need to take a different approach to removal. Here are some steps to follow: First, remove as much of the mold or mildew as possible using a stiff brush or broom. As always make sure to wear gloves and safety glasses during this process! Next, mix one part bleach with nine parts water and apply it to the affected area. Let the solution sit for about 15 minutes before cleaning it up with a wet wash cloth. Make sure to dry the area completely after cleaning it up to prevent any further mold or mildew growth. Find the source of the moisture such as a leaky roof or window and address it immediately to prevent future black spot growth. Sanding the surface may be necessary if you plan on refinishing wood flooring underneath the carpet pad. If you find that black mold growth is extensive, it might be best to contact a professional mold remediation company. You don’t want to risk your health by trying to remove large amounts of black mold on your own!
