How to restore that new look to your old stainless steel moka pot
I have owned a VeV (made by Bialetti) stainless steel moka pot for well over 30 years and made upwards of 40,000 brews in it. This coffee maker produces as much as 13 fluid ounces of brewed coffee. I use this with a gas range. Quite a few times I inadvertently left the gas flame on high under this thing without attention, and of course, this causes the pot to darken, stain very considerably, seemingly permanently. I have tried many many means to restore the brilliant mirror-like brand new look to the pot and only one method has worked, all others completely fail.
If a pot is merely stained by a light residue that hasn't penetrated the metal, it can be cleaned off with some Bon Ami and a small piece of wet cloth, but serious compromise of the surface of the pot caused by excessive heat has not surrendered to any of the many measures I have employed save this (I have done this before, and I did this again just a few days ago and my 32 year old pot looks close to brand new). The pot itself says this on the bottom:
Made in Italy
The only thing that really works for me is to use wet-dry (black) sandpapers. These sandpapers can (and usually should) be used with water. I start with a very coarse grade, either 150 or 180 grit and work successively all the way up to extremely fine grits:
It is necessary to use successively finer grades of sandpaper in order to work out the scratches made by the coarser grades. By the time you've used the 1500, the machine looks brand new!
Before each usage, I wash the exterior with a soft kitchen-spongy netted dish cleaning implement with some soap and water (and rinse). This really helps to keep the maker looking great.
For a real sparkly shine you could finish it off with a cream polish after the 1500 grit paper. I find Autosol works really well for things like this.
100,000 grit diamond polish works well as a finisher!
I bet it does!!!!!
