If I take steel wool to it will it go away and come back?

That's NEW rust, so use a fine steel wool to remove it. Then wax the piece to prevent more rust.

What I'm surprised and frustrated to see is that the day after I have rust reappearing on the metal?! Is that because I didn't leave things in the "soup" long enough or is this some kind of flash rusting because I towel dried the metal but moisture was still present and it was vulnerable? If I take steel wool to it will it go away and come back? Do I need to take a wire wheel to the metal even after electrolysis? I'm enjoying this experience but it seems like every question answered brings up two new ones.
I had the same problem after using Evaporust. Then I started coating the de-rusted parts with Penetrol, and haven't see a speck of rust form since. Penetrol is primarily an oil-based paint additive, so this treatment might be OK even for parts that are to be painted.

It’ll be great to see the photos.

What the guys are telling you is gospel. So long as those parts are exposed to air new rust will form. The only way to combat it is to keep ’em waxed or oiled to block that oxygen from the metal. It’ll stay lookin’ purty good from then on.

More of the gospel. After electrolysis a thin layer of porous 'pure iron' resides on the surface. It will react with air etc. immediately. In fact before you even finish drying it! A similar situation exists with evaporust once you wash it off.

Realize you have created pristine rust free surfaces which are just 'itchin' to get oxidized!
