aluminum siding

[ccapower]

what is the best way to clean aluminum siding that will not come clean with ZEP or scrubbing? I've tried almost everything and the siding still has a dirty look to it. Any help would be appreciated.

Try a product called snowcap, sherwin williams paint stores sells it. It is kind of pricey but I had rust and iron stains on my vinyl siding for years. I sprayed that on and within 10 mins it was gone, just rinsed off with a water hose.

Use the search function of this board. Just type in what you want to look for. Alot of information in there. Then ask again if you can't find your answer.
2 Step Process in some cases.

Tsp

I believe TSP is what you're looking for (trisodiumphosphate) with a couple of precautions...Use only the prescribed dilutions...Check the condition of the siding...Test a small area first, then pre-rinse with a hand sprayer and white vinegar diluted 1-1 (if the job ain't too big) otherwise just rinse thoroughly first.
If the electropainted-factory surface is damaged in ANY way, I'd either get them to sign a disclaimer or walk. If it's been repainted, drop back 5 and punt...BABY STEPS!
Good Luck!
