slowly getting duller and losing that shine

I had some various old wheel cleaners in the garage that I tried but nothing seems to do a decent job on stainless :S
I was wondering if someone could reccomend a product that they have used... that actually seems to work

Thanks in advance guys
Apologies if this has already been commented on but I couldn't find anything except for the usual talk about Meguiars/Armourall/Etc
