Homemade Evaporust Alternative

Interesting effect. Can you get another photo with sharper focus? And do you have a "Before" picure?

I've been very busy with rowing (4:30am-5:30pm)  and so have taken a while to respond, but it also means that I forgot to remove my test subject piece of scrap mild steel and it has been submerged for 5 days nowhere are three, rusty scrap metal, 5 days submerged scrap and my WI 12hr submerged

here is a closeup of the two scrap metals. The soaked steel does have a small amount of minute pitting, though I think it's a mix of pitting from rust and the solution. (The original steel was rustier that this comparison but i don't have a perfectly matching piece) the pits are ~0.3-0.9mm wide, very minimal, whereas on the WI they are much larger and varying.i have applied a light coat of rust prevention to prevent flash rust*

You can see that along the length of the handle there are varying degrees of corrosion. Before submerging i knew the handle itself was WI because I could very clearly see different parts of it had obvious layers/grain(like woodgrain) and you can see some parts of the handle are quite corroded whereas others are relatively smooth. I suspect this is due to some areas (more visible layers) having more of the silicate impurities and slightly layers. The end in the last photo was slightly more rusty so that may have contributed somewhat to heavier pitting. The head however, it did jot have huge rust pitting before the soaked, and now it does, I can also see areas with folds where it's reveals it too is WI. Unfortunately my camera can't get a good picture on the head but the pitting is a different shape (and larger) to that on the steel (which was soaked for 10x as long). So I definitely think it has an adverse effect on the wrought iron slag layers. this is the only before photo i have unfortunately, cropped from a larger so its lower quality. 

edit* ignore last photo, post is glitchesd and every time i delete it, it reappears
