Product review (2 stars): What is the lubricant oily substance exactly?
Seems to work good other than the oily substance which I hope is not toxic I don't know what kind of oil they use in there but you can't clean it out just by opening the ice bin it's in the area I think that you can't get to you have to take the top off and there are no screws to take the top off but all the oil I think comes from whatever they used to  lubricate the moving parts inside I cleaned it and cleaned it and ran even vinegar through it and still had the taste I even contacted the seller to ask them and tell them that I lost a little white plug and would like a replacement or by several replacements and I don't see Dellas website or anything in the manual as far as a phone number whatsoever
So it has not contacted me Its been a week so far
 I'd really like to know what type of oil they're using it if it's mineral oil and safe that's fine but I don't think that the grease  parts with mineral oil I want to know what the substance is  any other people have complained about this even after cleaning it there's parts that you can't get to inside that you can't clean that's why it's very possible that it could be toxic
And now I can't use it with it's missing little rubber drain plug
