KBF99 brushes kill 99% of bacteria and fungi on contact while you groom your horse with no harmful chemicals or dangerous side effects. KBF99 coats the plastic surface of the brush with millions of microscopic swords or spikes. KBF99 is also positively charged to attract the negative charge of the bacteria or fungus. Drawn to the brush, the organisms are impaled on the tiny spikes which ruptures the cell membranes. The impact of the positive and negative charges further destroys the microbe preventing any further growth or spread. Tested by Coventry University in England, KBF99 technology is a practical and efficient way to reduce and eliminate any coat and skin irritations your horse may have. With regular grooming you should see visible results in 7-10 days. KBF99 brushes are effective against strangles, ringworm, E-coli and mycotoxins. To care for your brush simply wash it in warm, soapy water. Do not use bleach.
