The dark spots are the carbon residue after evaporust reacts with the rust. It comes off with scotchbrite.

You know, there’s quite a variety of scotchbrite products, which type are you referring to here?

Not sure the name exactly, but it's their green heavy duty pad. Normally most of the black spots come off with some slight rubbing with the pad.

But for this LC III PSU, not sure it's going to work as it's pretty bad. I might have to resort to sanding it.

On a second look, I think it's fine... it's still the usual yellow color, it's just there's rust particles which is making things cloudy. I usually pour the stuff back into the bottle through a filter. But in this case, since I did use it on a battery bombed chassis, I'm going to take it to the hazardous disposal center and buy a new 1 gallon bottle.

I would hang onto it; it might be fine. I was pretty lazy and didn't scrape off much of the battery residue. Just don't mix it back into a larger container. I'm actually interested to hear whether a similar reaction happens in your case.

We'll see. I only had a single 1 gallon of it so this is essentially all that I have. Maybe I'll mark the bottle and keep it for heavy stuff and ensure I have a more pristine new 1 gallon for lighter things. Still don't smell anything so maybe it's fine.

Top part of PSU and bottom shield out of the bath after a few days. Not bad.



This is what the shield looked like.



And the PSU top:



The bottom part of that PSU was a disaster... needs more time in the evaporust bath. It's getting there, about 2/3rds of it is gone but still have some work. The bottom shield is also almost ready. The big chunk in the picture immediately above on the shield is gone. Just need to get it off the sides.

Wow, that evaporust really does wonders!

I wanted to get some a couple years ago, but I couldn't find it anywhere.
