    Default Polishing Aluminum Pots and Pans that have had teflon coating blasted off

    After blasting, the metal is slightly rough. What would be
    the best way to polish these smooth? Would need to be a flexible
    pad because the sides curve up and of course, the side to the
    pot is about 6 inches tall.

    Hi, Welcome to the Forums.

    Basically a polishing mop ! You can get these in a large variety of sizes and shapes. You might also need to obtain a suitable polish !

    Thank you! Glad to have found this site!

    I hear Mother's is a good polish.

    Hi Virginia,
    Aluminium pots that aren't non-stick are anodised. After sandblasting your pots are now raw aluminium which is unsuitable for cooking.

    Unless the OP knows something about MW then suggest use of a "mop" could be misleading.

    What they really need is a bench top grinder fitted with a polishing mop.

    However, unless they are just going to be put on display, I actually see little point in polishing them to high gloss finish as they will dull and scratch very easily so perhaps a "brushed" finish would be more practical?
    In that case a Scotchbrite type mop on a grinder could be the way to go.

    But I also agree with Jack, unless you are just going to boil water or use them for steaming vegetables etc the raw Al will not be that practical and you will be spending a lot of time trying to remove burnt on food from them. If you still have the grinder and mop it will help remove ny burnt stuck food from them.

    Something to bear in mind is that for the cost of a grinder and a scothcbrite wheel you could also buy a beaut set of SS or coated Al saucepans.

    After sandblasting it's going to need a lot of rubbing with different grades of sandpaper, then once smooth polish with a mop as described above.

    There are some good tutorials online these days.

    You don’t know that. They might have sentimental value.

    We have an induction cooktop so (Tin plated) Cu and Al cookware are of no use but SWMBO keeps several hanging up in the kitchen and I occasionally polish them up every now and the when I have the buffing wheels on.

    As for usefulness, the info is all over the place. After several google searches, I found googobs of info saying that unanodized aluminum is perfectly safe to use. I'm reading that commercial kitchens and chefs use them all the time for everything and don't find them any harder to clean than other kinds of pots and pans. Several forums are saying that they're safe even according to the Alzheimer's groups. So, I'm going to sand and polish and use unless I get definitive science otherwise or my experience tells me they're not worth it.

    Thank you for all the input!

    Hi Guys,

    Actually thinking about it, if they have been grit blasted, they might be good candidates for anodising.

    I wasn't referring to any safety factors such as alzheimers but the fact that Al cookware doesn't work at all on induction based cook tops as they only heat magnetic (Iron or nickel) based cookware..

    To get Al ware to work on an induction cook top they have to have an thick iron web or mesh implanted into the Al os the iron heats the Al.. The other way is to put the Al ware on top of a magnetic material. We have an Al Moka pot that we have managed to get working on our induction cooktop by placing it on top of a cast iron sauce pan. Some people say this is not a good thing to do to the cooktop so we have stopped using it.

    The other thing about induction cooktops is the cookware has to be large enough to pick up the alternating magnetic field to heat the cookware. We have another (smaller) stainless steel Moka pot that should work on the induction cooktop but it doesn't because its too small. We tried it in the same cast iron sauce pan as above - it works but its very slow.
