Cobra WashCOBRA is formulated for touchless vehicle washing, as it penetrates, lifts and allows for resistant road films, oil, grease and clay soil to float away quickly and consistently. COBRA attacks bug residue and carbon deposits on painted vehicle surfaces as well as on aluminium, painted wood and metal. Apply COBRA using high or low pressure, and rinse with high pressure (500 psi or greater), to leave the surface protected and glossy.
