So i found out like this tip is made of brass and regardless of color options. The options should be renamed to chromed brass or brass so that future customers are not mislead.
After steaming milk, milk gets caked on solid so I used a Scotch Brite to clean it off thinking since it's a stainless steel tip it would be safe. I don't mind scuffing up a polished stainless surface but the scotch Brite ended up rubbing off some of the chrome coating exposing the brass underneath. Wish I had known this before hand as I would not have used the pad to clean it.
Going into the coffee sensor official site the stainless extended tip description does indeed mention that this is chromed brass. I am not sure why coffee addicts edited the description to remove this note. Still works to steam but not that happy after finding out this product isn't exactly stainless steel
