I'm rather disappointed in the latest stainless steel bowl I bought. Left it in the sink unwashed from a salad for a week while I had to be away, came back and it had rust underneath and inside. Same has happened to few other bowls, pots and utensils over the years, all marketed as stainless steel.
At this point, the only 3 stainless steel items I have that are truly stainless and have lasted me over 10 years are a water kettle, a spoon and a pot that my mother gave me when I first moved out.
Everything else has either rusted or developed these black pits which I have no idea what they are. My dough hook for example gathered more and more of them until it finally snapped at one of the pits locations.
So how can I identify things that are really made of stainless steel? I want more things like my pot, its got scratches and discoloration from lots of abuse but is still shiny.
