I just purchased my first ss wash. It is a 4 bay unit on a major highway in the middle of a small town. The population is a little over 11,000. There is one 3 bay wash in this town already but it is located as you are leaving town behind a service station. The wash I bought has been closed for years. The mechanical room still has the pumps and everything in it but they are old. The wash was built in 1986 and I believe it is the original equipment. Im not sure if older equipment that has sat dormant for years is worth trying to fix? All the bay timers are shot and will have to be replaced for sure. The 3 bay wash down the road has coin only timers and vacs. I was wondering if it would be benefit me to put a change machine that accepts dollar currancy and credit cards or bay timers that accept dollar currancy. I would like any and all input or ideas that yall could help me start this wash back in the right direction.
