Wallmart SuperTech, summer formula. A few years ago, I had an opened, partially filled bottle of this stuff that had floating black mold in it. Don't know how long it was sitting on the garage floor. Never had one mold over since.

I can‘t answer this. I’ve tried spring, tap and distilled. Distilled is noticeably better.Curious why distilled water is a requirement. I could understand if you had some funky well water with a ton of calcium or something, can't see municipal tap water causing an issue.
This discussion of using methanol as a windshield fluid scares me. Methanol is highly toxic to people and pets and can be absorbed through skin contact and inhalation. It will also blind you if it gets in your eyes. A hard no on methanol.I'm not clear at all what you're saying really. But EtOH is generally less solvent than MeOH.
And that would apply to IPA as well, I've never seen any credible information it's worse on paint and rubber than any other alcohol. Sounds like Internet misinformation.
