Black Coating on Aluminum Meat Grinder from Dishwasher: Health Concerns & Safe Usage

Hi,

Unfortunately, the meat grinder was put in the dishwasher and a black coating appeared on it. I managed to partially wash it off with vinegar, but now I have doubts whether this device can be used further. I searched the Internet, but I did not find clear information whether this black coating only blemishes the aluminum or it can also cause health problems.

Regards and thanks for the answer

I used to work in a powder paint shop. Before painting, the aluminum was acidified so that the surface became rough and the paint adhered well. If too much debt was immersed in acid, it was just starting to turn black, but after painting it was completely impossible to see. I'm not a chemist, but I don't think it's harmful. The aluminum just got oxidized. The same as oxidation, for example, Silver at the beginning is beautiful shiny and then it becomes dark because it oxidizes and you have to go and acid and polish and it looks like new again. Put a hot water machine with citric acid in it for sure, but I don't know how much it will disappear.

I made this mistake with the Zelmer.
This black coating gets dirty and wears off, it will end up in the tar anyway. Even if it is "healthy", which I sincerely doubt, I do not recommend it.
The first solution is the purchase of a new machine in the sense of the body itself and the cap, probably the screw also landed in the dishwasher. You can also search in the secondary market. Maybe someone's engine broke down or something.
The second option, which I used, was first scrubbed with a cif.
Then I fastened the electric polisher paste g3 and wio in a vice. We wash it very thoroughly several times with the liquid.
On the outside, polishing on the inside requires creativity and patience, but it is possible.

I bought a new cork. I did not have the time and tools to play with cleaning the current cork.

I have kept the current body, maybe in the future I will be able to clean it and it will act as a spare part
