Our front porch posts and window trim were covered with white aluminum siding about 25 years ago and it has gradually turned gray. Is there a way to clean it back to white?

I have an aluminum white metal shed and tree sap was covering the top front and I washed it down with bleach water and liquid cleaner. It came clean and still looks great after a couple of years.
A contractor who does professional power washing can get the siding clean, and even remove mildew. If you want to try it yourself, get a professional strength cleaner (which comes in environmentally safe formulas that do not harm plants, grass or bushes), and mix it with regular bleach and water. The cleaner will probably give the right proportions for the mix. You can use elbow grease and a brush, or rent a power washer for the job.
