Burnt-on food and heavy grease deposits can really slow down the clean up. Try Formula G-510EF, our multi-purpose colloid cleaner. The colloids in Formula G-510 break up dirt into millions of tiny particles that constantly repel each other, so they can't stick back together and are easy to wash away. FORMULA G510EF meets the stringent criteria of the U.S. Environmental Protection Agency's (EPA) Design for the Environment program - a program that works with manufacturers to develop safer chemical products that also meet high performance standards. The Design for the Environment (DfE) label allows consumers to quickly identify and choose effective products that are safer for families and pets and help protect the environment. Formula G-510EF is non-hazardous, non-toxic, non-caustic, non-fuming, non-flammable and non-explosive. It contains no phosphates, nitrates, enzymes, sulfates, sulfonates or silicates. Just add Formula G-510EF to your Gaylord washdown system, and let its concentrated formula go to work safely and effectively. - Volume 1 gallon per bottle - Sold per case; there are four 1 gallon bottles per case
