MMR MOLD STAIN REMOVER EFFICACY TESTING

The purpose of this testing was to determine what effect MMR mold stain remover, hereby referred to as MMR had on three different types of fungi (molds) on two different types of wood based building materials.

MMR was also compared to the effects of ordinary bleach (6% sodium hypochlorite) as well as another brand name disinfectant, hereby referred to as BND. Three different organisms were used in the testing. The organisms were Paecilomyces variotii, Chaetomium globosum and Ulocladium chartarum. These are common molds and often recovered from water damaged building materials.

The viability of the organisms after treatment was evaluated as well as any morphological changes of treated fungi as compared to a control sample. Viability was assessed by culturing post-treated samples and any morphological changes were documented photographically.
