I always wash the wheels first and get all the dirty sludge out of the way. I then use clean water and microfiber cloths for the next stage of the wash.
Start by thoroughly rinsing the car’s surface to remove loose grit and surface dirt. Get your microfiber cloth ready by soaking it in warm soapy water if available. I use two buckets – one bucket holds your soapy water and the second bucket holds rinse water. Rinse your microfiber cloth in the first bucket before you dunk it into the soapy water. Then starting at the top, wipe down everywhere on the car with the soapy microfiber cloth. Use an open hand when doing this to increase surface area. Clean the wiper blades and leave them up. Once all the dirt has been removed with the cloth, rinse the entire vehicle off with clean water; a hose works best because of the pressure, keep going until all the soap suds are gone.
