Then there was this crazy idea ......
Is it possible to wash your car just with air to avoid water wastage ......... without water
Methodology :
a. Apply the washable solution on the car ... <scrub the dirtiest place with sponge> ...
b. Then proceed with pressurized air on the car surface...
PS: To be noted that .. Do not overpressure the air as it would damage the surface of the car ...
c. Proceed with applying car wax and wiped it off with the appropriate machine...
Waaaalah ... we are done washing without wasting water
This equipment is mostly recommended which would be applicable where the is limited water resources.
