Does anyone have any experience with Galvalume? We've cleaned many different metal roofs but I just want to make sure I'm going after the Galvalume the right way. Any input would be helpful.

Bare finish. I was planning to do a test on a small structure.
I've never cleaned it but installed a lot of it when I was a roofer. Used to buy it under two names. "Galvalume" which was bare. "Acrylume" which looks the same but is coated with a clearcoat.

The customer had it installed when he built the house and says it's Galvalume so I am hoping it will clean up like other metal roofs.

It should clean up ok, but a test spot is necessary. I did one a few year ago and the cut edges and work seams turned a little rusty after the cleaning. It came back after a few rains but was a little odd. It was the steel base layer showing through the Aluminum Zinc coating. On cut edges and field penetrations usually the steel is bare and can weather differently than the other coated parts.
