My mother often used what she called “the metal sponge” for difficult cleaning in the kitchen, such as removing baked-on residue from pans.
As I recall, the sponges were more coarse than a Brillo pad, consisting of small curlicue turnings, such as would be swept up from a machine-shop floor (where they could have really originated). Hers were of copper to avoid rusting while they were stored. A good product, but I never saw one in anyone else’s kitchen.
Now, I have found something even better at my local hardware store (not one of the big boys like Lowe’s or Home Depot. They even carry replacement glass tops to percolator coffee pots.) Theirs is of the same small curlicue turnings, but of stainless steel. I did not save the wrapper, so I do not know the brand name. As fine as the turnings are, they are coarser than the coarsest grade of steel wool, but they do not cut your hands.
I don’t remember what I paid for it, but it was well worth whatever it cost. I use it everywhere: kitchen, garage, and basement. My mother used it often in East Lansdowne, and so do I. I kid you not.
