Easiest way to get the hamon whiter is to use hot lemon juice mixed with water and a dash of dish detergent and mothers mag to polish it after the blade turns black. After a few cycles you will notice the hamon change to a more prominate one.
The downside to this is that if you have a cross polished kissaki it with fade the yokote and make it look more like a shobu sugata.
Not to mention the possibility of cutting yourself.

Leave it alone. Etching can dull the blade if you are careless in over applications.

So there are a couple ways to do this.
Contrary to popular belief you don't need to heat lemon juice for the etch. 3-4 lemons worth and a teaspoon of dish soap. That will etch. The idea is you actually darken the jihada more than you "whiten" the hamon though some whitening occurs. Neutralize the etch with Windex (the ammonia will deactivate the acid).
Polish with SiC and oil mixed to a paste after (mothers mag and such can work but your SiC/oil paste will create a more satin Nihonto look; this also will bring out Ashi more if done correctly).
Another insider trick is use magnatite (black ferrous oxide) mixed with some oil on the jihada post etch and pre SiC polish pass.
This will give the jihada a slight blue hue and further darken the jihada for that Nihonto polish look.
Note: make sure your blade is absolutely clean with denatured alcohol or mineral spirits before doing this.
