Oh yes...I don't have a consistent problem !

Mine will squeal if I run thru a deep puddle and water splashes up into the Belt or if I leave
my parking lights on when I go into a store.

The battery goes down and then on startup the Alternator is heavily tasked and the belt
squeals.

BUT - If I turn everything off, it usually quiets right down - then a few minutes of charging the battery
all by itself, and I can go.

That is why I asked about a battery drain.

Just a small drain and the Alternator is working hard for maybe a minute.

Heavy fog will condense on the Belt and make it squeal until it dries off.

I think that once a Glaze forms, you are screwed royally.

The WD-40 thing does seem to work in some instances.

I saw somewhere that the Glaze is "water soluble". Strange if true.

I have never tried washing with Windex, or 401, or maybe Comet Powder, or Babo, Kleen King for Stainless Steel would abrade
the Glaze off - acting as an abrasive in water - use with a toothbrush!

Hey - maybe sprinkle some Comet Cleanser, Babo, or "Kleen King" Stainless Steel powdered cleaner
right onto the pulley and let the belt clean the pulley just by spinning...
Then spray some water on it to wash the powder off while the engine idles.
Might work. I'll try almost anything once....except Russian Roulette.

If one could change all the pulleys for twice the width, this problem would disappear, in my Humble Opinion.

The Belt chosen by the designers is a marginal one.
