ShockWave is an EPA registered disinfectant, sanitizer and cleaner designed specifically for mold and mildew remediation. ShockWave is designed to be diluted two ounces per gallon of water, yielding 64 gallons of usable product per gallon of concentrate, making it an economical solution for cleaning asphalt or concrete tennis courts with acrylic coatings. ShockWave is strong enough to be used as a hospital grade disinfectant and has been specifically formulated to be used on both porous and nonporous materials. ShockWave disinfectant and mold/mildew killer does not contain chlorine bleach and will not "bleach" out stains. Some scrubbing may be required to remove residual stains from surfaces. Periodic treatment of shaded areas prone to mildew will prevent the mold and mildew from becoming well established.
