G-WASH™ Heavy Duty Hydrophobic Car Wash is a highly concentrated cleaner/degreaser which uses the power of nanotechnology and American grown base oils to tackle the most difficult cleaning job. G-WASH™ is a hydrophobic solution that causes water to "bead up" and roll off, leaving NO SPOTS. It is not a soap or detergent or petroleum solvent but a blend of natural plant based products. G-WASH™ penetrates into dirt and oils, then breaks them into billions of little particles that constantly repel each other. This makes it impossible for them to stick back together and form spots on your car's surface. G-WASH™ even removes dirt from your wash cloth allowing it to last 10-15 times longer.
