Detergent thickeners may be responsible for biofilm growth leading to dangerous "chemical-resistant bugs" in a washing machine.
Biofilm (a bacterial slime layer) takes form initially deep in washing machines with the help of soap slime.
Incoming bacteria accumulates inside the biofilm.
Good bacteria, may enter the biofilm, spawn with-in the slime layer, and engender dangerous resistant bacteria.
Therefore, "Resistant Disease-Causing Bacteria" can and often does spawn In washing machines.
From the washing machine, to your fabrics, live pathogens inflict skin pores for unsuspecting millions of people.
We highly encourage doing a strong electrolyte washing machine flush.
