Hot take: I tried a 50/50 mix of water and vinegar for cleaning a boiler tube bundle and it went really wrong.

I was on a shutdown job in Cleveland last month and a guy on the crew swore by it for light scale, so I gave it a shot on a small section. The mix ate through the scale way too fast and left a weird, almost sticky film that took twice as long to scrub off with a wire brush. Has anyone else had a bad result with a homebrew cleaner like that, or did I just mess up the mix?

Yeah, that re-deposited gunk sounds like the worst part. I've seen that happen before with a citric acid mix that went too hot too fast. You end up trading one problem for a stickier, harder to remove one.

Ugh, I had that happen and @the_tessa is right, a cold soak with vinegar first worked way better.

That "weird, almost sticky film" sounds like it re-deposited... the acid pulled the scale off so fast it just stuck everything back on the wall in a new, worse way.
