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.
2 of my golf cart batteries are 11 years old which i revived with epsom salts and a desulfator, I replaced the acid in my batteries with distilled water and dissolved epsom salt and left the charger on for two days.
