Blender part in dishwasher, poisonous? I washed a part that should not be washed in the washing machine. Now the metal part is no longer shiny and gives off an oily substance. How dangerous can this be? In terms of toxins and to the other things in the dishwasher? I did a quick wash without soap after I found out.

Edit:
Awaiting answer from tech support, they might have to ask the factory. I think its strange that the inside of the cog is covered in oil, if its from the part above. There is no visible oil on anything else, even on the plastic or the blades. I think it may be a coating on the cog, reacting to water and soap, may be completely wrong here.
It seems that oil has been driven out of the bearings.

For getting rid of oil contamination, soap is actually very useful. One or two empty runs should certainly get rid of what is left in the dishwasher itself, even if the oil is not food grade - otherwise, everyone running a dishwasher professionally would have to be worried about someone having eg touched a cup or plate with motor oil on his fingers.

Check if the bearing still runs decently; it might be best to take the bearing apart and re-grease it (this one looks like it is designed to be taken apart) - check whether you can find a repair manual and/or advice from the manufacturer on what grease should be used here.

If you use any non-approved type of grease, pay heightened attention when using the blender - any strange noises, smoke, slowing down... mean turn it off now.
