I received a mixer for my wedding shower in 2018 and recently my husband ran the beater through the dishwasher - normally I would hand wash it just out of an abundance of caution, however, after run through the dishwasher it was as if it lost the silver coating and it was a dark, ashy grey. It also smelled like metal and I ended up throwing it away as it seemed as if it would taint the flavor of anything I used it with. When I did use prior to this, it worked well.
