What customers say
Customers highly value this cleaner for its powerful dual action: effectively removing existing mold and mildew while simultaneously blocking future growth. Users report excellent results on challenging outdoor materials like marine vinyl and RV awnings, lifting stubborn stains without causing discoloration, unlike harsh bleach products. The formula is perceived as safer and less noxious, simplifying application. Although priced higher, the consensus is that the superior cleaning quality and the convenience of combining two steps justify the cost, especially for protecting valuable assets. While some desire longer lasting preventative effects in very humid conditions, overall satisfaction remains exceptionally high due to its immediate cleaning prowess and material safety.
