I_ really happy with this purchase. It_ well made, strong, easy to clean and is holding up well with our daily milking routine. When it arrived, it had a strong smell that initially concerned me. It wasn_ a chemical smell but appeared to be related to production somehow. The underside of the can was covered in a thick black layer of wet dust or grease that we cleaned very thoroughly before use. Even though it was on the outside, we didn_ want to take any chances. I have no idea what it was but it did come off without too much fuss.
