I have some stuff from Lagostina, because that is the brand of stainless steel pots I have. I don't use it often, but once in a while when all my other tricks fail to get something off, I use it. It works well. It seems to do it without any scratching of the surface. It also takes off stuff that built up slowly and evenly, so you don't even notice it's there, until it's gone.
May you live as long as you wish and love as long as you live.
