There are a variety of different brands and types that you can use, but one thing is for certain, which is that you need a sponge! A big sponge is best to cover the large surface area of the car. The choice is yours whether to use a synthetic or natural sea sponge for the job. A sturdy bucket is the next of the car wash supplies. You can use any sort of bucket, provided that it holds at least a couple of gallons of water. A bucket and sponge would be no good, however, without some car wash soap! There are many different types of car wash soap that you can buy, but make sure that the kind you pick is specially formulated for washing your vehicle
