Natural Sea Sponge! Advantages of this is that it naturally expells dirt and trash that is caught in it and it actually get's cleaner the more you use it. Also, it holds suds better and water better, so less trips back and forth to the bucket.
Car is dried MUCH quicker if you do the following....take the spray nozzle off of the hose and lets water pour in a smooth sheet over the car, this eliminates spots of water that are left behind....Then...I used to use a Chamois, but have since discovered "THE BIG BLUE TOWEL"!! Dries the whole car with no wringing out at all (In fact it dries my wifes entire Explorer without wringing out once!)
