Quick response to small hydrocarbon leaks and spills on land or water. The Oil Mop's fast-wicking pads are designed to soak up 25 times their weight in oil and other petroleum products, but will not soak up water. The polypropylene ”oil only” sorbent pads are cut to fit — easily removed and replaced after they have been saturated. The foam core allows the mop head to float on top of the water and pull off oil, gas and hydrocarbon sheen that floats on the surface of the water.
