You know, the whole car is on the chassis of your car and most of hard parts of the chassis belongs to the underside of the car. If the this chassis get corrosion and loss its hardness, the whole car including you are in big trouble. So we must keep it corrosion free always. For that purpose we need to clean it in shorter intervals.
This can be easily done at a service station for some
less amount of cash.But even if the better way is to going to a service station, you can do it at your home at a low cost. You just need some brushes, car wash detergents, a high pressure water supply ( high means high OK) and a way to lift the car for some amount. Since this is a routine process, you can prepare a small ramp using something like concrete at your back yard with the help of a mason and you may prepare the high pressure waterline using a water pump connected one end to your home water tank and the other end to high pressure pipe fitted to a smaller nozzle.
Using a system described above you may properly wash the under body of the car very easily. After washing, allow the underside to dry properly. If your car is a new model, the job is almost finish now. But if you have an older car that only has underside with only metallic surface, grease the underside with a grease pump properly for added safety.
