The car body should be degreased with a special agent at least one a year. Such fluids contain unique substances that are able to remove bitumen, fat and oil stains from the surface. Degreasing solvent will successfully cope with asphalt coating and rubber crumbs. Degreasing agents should be applied to the car body after washing. A soapy foam and water remove dirt from the surface and then the degreasing solvents will remove worn-in spots. And remember, degreasing agents should be applied to a dry surface that is why you should sop up the water with a cloth or let your car dry. After application the fluid leave it for a few minutes. You will notice the spots slide along the solvent. Then the car should be washed with an active foam. The result will be fascinating – the car body will be absolutely clean and shining.
