Interesting. A web search suggests it could have been algae, but the web site below (among others that have similar
text) claims what you dealt with was (probably) a formation of wax and asphalt. I can see how the latter two would be
a pain to clean out! Did you try anything like the product known as "Goo Gone"?

No, I was not familiar with Goo Gone then (this occurred in about 1980). Yes, I think this was more than simple algae,
but I know it was the most tenacious coating I've ever seen on aluminum!

Maybe "simple green" would take it off.... ;-)
