Found the same thing at a manufacturing plant a couple years back. Server login was literally 'password' and IT swore it was fine because "nobody knows the IP." Fixed it myself, changed credentials and set up 2FA, then sent a brief email to my manager saying I discovered a security risk and resolved it. Didn't name names or make a big deal about it. That got me a meeting with the VP, who was actually grateful I handled it quietly instead of making the old guy look bad. Ended up getting a small bonus for catching it. Sometimes just fixing it and moving on is the smarter play, especially if you don't want drama.

Man I feel like every time I say "yeah I got it" my brain immediately goes "no you don't, check again." My checklists now have checklists.

I used to think torque specs on small bolts were just suggestions, that experience changed my whole approach.

Oh man, yeah, I've messed around with hydrogen peroxide on lenses before too but never thought to mix it with ammonia. Chuck knew what he was doing. I usually do a drop of dish soap in warm water with a q-tip for the real stubborn stuff, then follow up with 91% isopropyl to get rid of any leftover moisture. The trick is to not scrub too hard even if you want to, fungus can etch the coating if you're not gentle.

Three hours with a hand spade sounds miserable.
