Our product does not destroy plastic, rubber or fitness equipment. Our active ingredient is 0.046% hypochlorous acid in solution with 99.50% electrolyzed water. There is nothing in our product that can harm plastic, rubber or fitness equipment. The short effective killing cycle allows you to safely put your equipment back in use more frequently. Any business renting bicycles, kayaks, canoes, and any other equipment should use a human-safe disinfectant. Presently many use sanitizers, but a more powerful disinfectant should be used. Also, hockey equipment, football pads, skates, music instruments and other personal use sports, music or recreation equipment would be safer if disinfected. Frankly, even if Covid-19 had not emerged, it would be wise to use Pure Defender disinfectant products.
