Al. siding

What chemicals do you use to clean Al. siding? I understand that TSP should not be used to clean Al. Also, will TSP hurt glass? What causes Al. to oxidize? I notice paint runs when cleaning Al. siding.
Thanks,
Mark

Mark,

Currently, I use Gutter Zap to wash aluminum homes. Just have to be certain to get it all off of the windows. Gutter Zap does wonders on gutters (dilute 2 to 1)
I also use it on the alum siding, but dilute it 10 to 1 or so.

I am always looking for a better way.....I'm curious to see what everyone else uses.

If there is mildew present, I use a different cleaner, with some bleach mixed in.

Also, I never use more then 2000psi on alum. siding.
