Things You'll Need

Instructions

1

Remove the dirt or debris from around the mold spot on your felt fabric. You can use a light brush to sweep away and loosen up the dried mold for easy removal.
2

Take the baking soda and cover the moldy area on your felt fabric. Be sure to cover it completely, going about an inch out from the moldy area. This will help to ensure that you are killing the mold and preventing it from spreading.
3

Spray straight vinegar from a bottle liberally onto the affected area. If you do not have a spray bottle you can pour the vinegar onto the affected area, but use caution. The vinegar and the baking soda will create a chemical reaction that will cause the combined mixture to bubble up, making a foam. Let the mixture sit for about five minutes so that it will have time to kill the mold. You can also use the brush again to help loosen up the mold and get the mixture through the felt so that it can kill the mold.
4

Use the water to help clean up the mixture of vinegar and baking soda. Blot the area and apply pressure to soak up the cleaning mixture. Be sure to keep using a clean area of the towel so that you are not spreading any of the mold or adding any dirt to the clean felt.
5

Allow the area to dry completely and then use the soft brush again to help soften up the felt, as it may be stiff from being cleaned.
