I'm getting unhappy with the general gunkiness or at least non-newness of my Rockwell 6S and GC .84, both stainless steel. Running them under water after usage isn't cutting it. Is there a liquid product I can dump in a bowl and let them soak that'll get them back to that NIB condition or close to it? I don't really want to do detailed cleaning work on them; I'm hoping there's a solution I can submerge them in for a while and then wipe off.
