I've already tried bar keepers friends without much luck.
It's quite possible it's been bleach soaked, although it's not pitted at all.
If it has been bleached what could be done?
So an update on this, I've scrubbed with BKF which hasn't really done a lot, I've soaked in citric acid and again no change in appearance - any other help is appreciated thanks!!
Hey,
I've got hold of 2 stainless steel pots, but they have some discolouration inside, can anyone help work out what it is and if anything can be done about it?
I don't imagine it would effect the brewing?
Thanks
Mark
