Do not use the dishwasher. When i retired in 2002 I had about 12 hydraulic power rams of assorted sizes. I figured I would never use them again so I better sell them. I started cleaning them up and got the bright idea that the dishwasher would work perfect for that. It did sold them for $1000 to a construction company.
The down side. My wife caught me with them in the dishwasher. I survived that day, barely. I think I have heard about how I messed up the dishwasher at least once every day since, more when she is using the dishwasher. She claims the oil is in the machine and the only solution is a new dishwasher. That was a new dishwasher. Well sometimes it is better to give up the fight, it is the only way to win. I told her to go out and get a dishwasher. That was a couple years ago and she has not replaced the dishwasher yet.
I think she likes giving me a bad time more than she wants a new dishwasher. So a word to the wise from a guy that found out the hard way. Never touch the dishwasher. Buy a used one and put it in your shop but never use hers.
