When I used to do the lanes, there was no water involved in oiling the oiling machine. The only water was from the stripping machine that I used prior to oiling the lanes.
Now-a-days, the oiler and stripping machine are one in the same. I could see where maybe water/cleaner may be leaking from the nozzles and onto the lanes when the machine is coming back toward the foul line. This could be nasty to say the least.
