Yeah, isn't that normal precipitate?

I'd be worried about if there's ash from the burn off that then mixes with water to become lye. Not sure if there's more of a chemical reaction necessary than that.

I had a vinyl wrap on part of my car and some ash from California brushfires fell on it, and then it rained a month or so after (I was procrastinating on properly washing it off) and the lye produced ate through the clear coat of the vinyl.
