While foam is a porous material and generally doesn’t soak up liquids like a sponge would, moisture can still seep down into the foam and cause mold and mildew. Mold can happen quickly and moisture can deteriorate your foam. It is hard to tell if molding has already started to happen, so we can’t guarantee your pieces are safe to keep using. However, there are a few methods you can try to dry the affected foam. If it’s a small area and the spill was caught quickly, you can blot the area with an absorbent cloth or paper towel. Then use a hair dryer on the high setting, 3-4 inches away from the foam. Prop the affected piece up, allowing both sides to be exposed to air. Place a fan on either side and turn them on high. Air circulation can help speed up the drying process.If it’s warm outside, you can take the foam out into the sun. Make sure both affected sides are exposed to air circulation. *Note that bare foam exposed to direct sunlight can cause oxidation, a harmless, yellowing of the foam.*It is better to over dry your foam than leave it damp with moisture inside. If you don’t think you can fully get the piece dry, please dispose of the foam!
