I am the Chief Marketing Officer for the Endurance BioBarrier line of mold cleaning and mold prevention products. Our mold cleaner is powerful yet non-toxic with no harmful fumes. And our mold preventative spray uses a microscopic high-tech polymer to bind a unique blend of EPA-registered biocides to any indoor/outdoor surface. As a result, the biocides invisibly remain on the target surface eliminating 99.9% of microbes through hundreds of wet-dry cycles. Other mold preventatives get diluted or rinsed away when first exposed to water or condensation. As an added benefit, our mold prevention spray is certified non-toxic with no harmful fumes.
