Bright Solutions® Silicone Emulsion Defoamer for Carpet Extractors - 4 Gallons

A defoaming agent, like this Bright Solutions Silicone Emulsion Defoamer is necessary to keep your recovery tank from overflowing with foam and potentially damaging the vacuum recovery motors on your carpet extractor. Simply add 2 - 3 ounces per 5 gallons of the recovery tank size. A great way to do this is to suck up the defoamer directly through the vacuum hose in to your recovery tank. This will effectively prevent foam from building up there. Why kill foam in your recovery tank? Too much soapy foam in the tank will be taken into the motor and eventually cause breakdown of that motor (and a costly repair). Better to prevent the foam in the first place.
