Step One - Clean the Cart. You will need to wash the golf cart so it is spotlessly clean. Use sponges and scrubbing brushes to remove all stubborn areas of dirt. Use hot water because this will soften up and debris and make it easy to remove. Tackle all areas until you are happy that the cart is as clean as it can be.
Do not let the pressure washer beat on the vital parts but a good thorough washing is fine. Many golf clubs wash the battery compartment out every daythis is great! Several times a month is good, once a month is ok, and certainly at seasons end at a very minimum.
