Our method is all natural. We use a baking soda blaster to quickly remove mold from the wood while providing minimum impact to wood surfaces. It is applied in a dry granular formulation. Besides being an all natural remedy of killing mold it also acts as a deodorizer. Once the mold removal process is complete we apply a borate application to protect and preserve the wood. This process fits in perfect with our mold remidiation procedure because we are licensed to apply this product. You have to be certified in New York State to apply Bora care with Mold care. http://nisuscorp.com/the-borate-story.
