So I decided to give caustic a go cleaning my Braumeister after my last brew. All went well and it did give the stainless a new sparkle.
Brewed again today and everything went fine, but then when I pulled the pumps apart after cleaning, I noticed a reaction on the brass pump housing - whoops - forgot that part wasn't stainless:
This has obviously happened in the couple weeks since brewing - I didn't notice this immediately after cleaning last time.
I have read everywhere that caustic and brass are not a good combination because of 'reactions', but I can't seem to find any specific info on the internets about what those reactions are - is the brass still food safe? Is it going to continue degrading into the future?
I actually got the idea from another BM brewer who's been doing it for some time - obviously no major issues, but I am not sure how often he inspects the pump housing.
