Your source for waterless car wash
Both are suitable, and can be purchased at most grocery stores. I have seen recommendations for two separate sponges to be used, one for the wheels and one for the chassis, if you would like. It is a good idea to at least dry off the outside windows, if not the entire car, after rinsing. Using a household glass cleaner with paper towels to wipe down the inside of the windshield and windows is ideal. A rubber protection spray can be good to apply to your tires after car washing.
