Lets face it ..if you get a load of those MVS carts coming out of China,Whew do they need a good cleaning inside.
I don't disagree with the dishwasher usage...I just don't have one.
I'd say with dishwasher usage much patience is involved...You must make sure to dry them and or give them enough time to dry/plus be able to check if they are dry......."I'd" be weary to wash anything(carts) with socketed chips/daughter boards or repair wires...

Years ago: a friend of mine had an accident,his car went into a Lake after spinning out etc...He had a an expensive car stereo system in the car.
The car was underwater..when he got the car out it was totaled,but he took out the car stereo ..Something burned out in the Radio and the speakers were wet but the Big Amp totally full of water worked again after a few days of drying..
And all he did was put it over a warm house radiator.
