Polarized fershure.. but the explanation for collecting 'dirt' seemed more a physical chemistry attraction and not an actual chemical (bonding) effect. Old too, so maybe by now someone actually Understands.

I've used some Industrial detergents which acted as if they'd clean carburetors; in fact, they did! :-)

(Hell it may be as subtle as the fact that, were there no hydronium molecule performing weirdly as it does: we wouldn't be having this conversation)

PS another "long chain polymer" ~ like a detergent -- is the active ingredient in Tweek\ufffd 'contact enhancer' whose amazing property is that: under [sufficient] pressure it conducts electrons but is otherwise a good insulator! Sufficient turns out to be - most electrical contacts except the really 'soft' kind. And.. it's alcohol soluble, making application EZ. The first Cure for lots of kinds of intermittents, now proven in really tough environments.
