This has most likely been discussed before but....
Does anyone have a dishwasher in their workshop for cleaning parts.
Do the parts especially aluminium discolour after using the dishwasher.
If they do is it the detergent used, or is it the heat of the water.
If it is the heat, and it can be turned down will this make it much less affective as a cleaner.
Do you add degreaser to the machine like in a parts washer or spray them, let them soak and use the washer to do the final cleanup.
I have been offered a dishwasher but have to weigh up if the value of it overrides the hassle of finding a spot for it and plumbing it in.
