I've noticed that the stainless steel interior of my professional brands tend to stay pristine. Where as my "made for home" brands tends pit and the interior finish is marred and scratched. All of my SS pieces claim to be 18/10 on the packaging. Below are the pristine pieces from workhorse to least used. When they get burnt bits that hot water or vinegar can't take off they get cleaned with BKF. I use the same gentle method for cleaning all of my SS.
* Berndes 9.5" deep skillet
* Anolon 10" skillet
* All-Clad 8" frypan
These are the pieces that have the marred, scratched, and salt pitted interior. Again from most to least used.
* Schulte-Ufer ecoline 1.5qt sauce pan
* Emerilware 2qt sauce/saute pan (Made in China by All-Clad)
The only piece that is not made in China is the AC 8" frypan. Sometimes I think not all the manufacturers producing the 18/10 SS sheets are equal. All-Clad claims their SS and other materials all come from a US supplier, for cookware thats made in the USA. However, the Berndes and Anolon are made in China. Where their SS sheets come from is unknown. Their interior looks as good as new.
So has anyone else noticed any difference in the SS quality of your cookware? Or is stainless steel is stainless steel and it makes no difference who makes it or where it comes from?
