Alcholol won't soften the baked on paint of the aluminum gutter.

Go to Ace Hardware and buy a gallon of their aluminum siding cleaner.
Takes that stuff right off.

I painted mine with semigloss white exterior latex paint. They don't get
as dirty as before and just clean up with soap and water.
It'll probably takes less time to paint than the time it takes for you
to clean them.

I have never cleaned any white ones but Lowes had a closeout sale for
some kind of plastic drip edge to snap on so they never get streaky
again. They had a big drum full of them but they are probably gone in
