Was the equipment working?? Doesn't need to be replaced then
Worked on several car washes for many years. Has to be one of the worst enviroments on anything not Stainless steel. I was always amazed that they expect relays, terminals, starters and other electrical stuff to work anywhere in the tunnel. In Maine, people wash their cars when the temps are below zero, you can't see from side of the tunnel to the other from the water turning to fog(going thru dew point). That fog is full of very corrosive chemicals found in the soap. Gets on and in everything.
