Tomorrow I have my first aluminum siding job. It is white and has alot of algae on itself and the gutters. I downstream and use a 5 gallon bucket for my sh. Any advice on how I approach this would be greatly appreciated
You asked this exact thread like 3 days ago…cut your SH in half from your usual HW mix, and have at it.
You’ve only read 26 minutes, keep reading. Lots of posts on the subject.

I guess I did. Different job. Not oxidized. More algae
All that changes is you have to be even more careful about pressure if it’s oxidized, and more algae may take a longer dwell/multiple applications…but I have yet to see aluminum that isn’t oxidized in 2022…
