Wash the car with Car Shampoo and Foam by Car Alchemist to remove any surface dirt.
Use Clay MicroFibre Wipe like a wiping cloth after applying OLIMA clay lubricant or using the foam wash as a lubricant medium.
Once done, rinse vehicle with water and wipe dry with a clean Microfibre cloth.
If the surface is still dirty after using the clay cloth several times, please replace clay cloth with a new one. Continue usage might result in scratches on the paint surface.
