A warm water and soap rinse is all I use for my stainless steels (cpm-s30v,vg-10,cts-xhp). Just keep up with oiling the pivot when needed.
As for steels like M4, d2, SB, etc that are not stainless----same protocol with warm water and soap, but you not only need to keep the pivot maintened with oil, but treat the blade with oil, tuff glide, etc. that is of course unless you want a Patina
I am sure others will have more input. Just my 2cents.
