Other safety gear that you can consider include protective goggles, a respirator, and coveralls. If you do not have all these protective gear, you can always improvise but choose good quality materials that can easily be cleaned or disposed of after the cleaning.
3. Vacuum the surface
Make sure you use a vacuum with a HEPA filter in sucking up mold and mold spores from the surface of the wood. As you vacuum, ensure the mold gathered is in a tightly sealed plastic bag for disposal. Otherwise, you may simply spread it to other areas in the home.

This will help you retain the nice appearance of your wooden items. You need to scrub the affected area gently in circular motions until the black coloring is no longer visible.

5. Sand the area
The essence of this process is to prevent further growth of the mold after you have cleaned. You need to ensure that you remove all the roots of the fungi. Sand the area then repeat the scrubbing as done in process number 3 above.
6. Dry the area
When you are satisfied that you have thoroughly cleaned the affected area, remove all the residue from the area and allow it to dry properly. You need to carefully put all objects that came into contact with the black mold into the garbage bags for disposal. To be more cautious, tie the garbage bag with tape so as to avoid the mold debris from spilling and contaminating otherwise clean areas.
