Unfortunately besides my Dualit Milk Frother requiring a repair (see How I Repaired A Dualit Milk Frother Model DMF2) another problem has developed. I have to ask, “Is my Dualit Milk Frother corroding?” If not what is happening to it. Is the brown mark I can see copper or rust?
Is My Milk Frother Corroding Or Not?
The surface coating (paint) on the inside of my Silver Stainless Steel Milk Frother (Model DMF2) bowl is either coming off or my milk frother is corroding.
At first I could see a small brown mark, which wouldn’t wash off, inside the Bowl. I thought the mark I could see was some burnt on milk. So, I had a little poke at it and instead of the mark coming off it got bigger.
The grey/silver coating on the inside was coming off. At first I thought there was rust developing under the coating. “Surely the bowl can’t be made of something like mild steel or there would be a problem with the magnetic drive to the whisk.”
What Is The Bowl Made From?
Well It’s definitely not ferromagnetic (a magnet won’t stick to it). I thought it was supposed to be made from Stainless Steel (much of which is non-magnetic) but perhaps it’s just the outer Jug Body that’s made of Stainless Steel. Take a look at it below.
There is a possibility that this bowl is made from copper and we can see an oxidised surface where the coating has come off. The only good thing here is the problem isn’t getting worse.
The bowl could of course be copper plated under the paint (on the inside at least). The bottom of the bowl on the outside where the whisk drive magnets rotate is silver metal and not copper coloured.
Another interesting point can be seen in the centre of the bottom of the bowl inside. The coating has been worn away by the rotation of the whisk spindle which comes into contact with the bowl. The metal exposed by this is shiny silver. I wouldn’t expect it to show any corrosion because it is forever being polished when the frother is used, but it isn’t copper coloured either. See below.
I have searched for corrosion within milk frothers generally on the internet and not yet found any references. So as yet I haven’t drawn any conclusions other than that something has gone wrong with my Dualit Milk Frother and I have to continue living with the question, “Is my milk frother corroding.”
