Why Pressure Alone Is Not the Answer


The instinct with mildew is to hit it with a pressure washer and call it clean. What actually happens: the visible stain lifts, the spores remain, and within a month the stain is back — often worse, because the pressure stripped the surface and gave the spores a rougher substrate to grow on.

Mildew has to be killed, not just rinsed. That means a biocide treatment with proper dwell time, agitation where needed, and a final rinse that protects the coating underneath. Done right, the stain leaves and does not come back for years. Done with pressure alone, it is back before fall.
