The secret to house washing for aluminum siding is using the right method, not the most pressure. In Indiana, we match the cleaner and pressure to the surface so it comes out clean without damage. On aluminum siding, the method we use is soft wash.
Method and pressure
Cleaning solution: A gentle detergent solution; strong cleaners can dull the finish further.
What to know about cleaning aluminum siding
Older aluminum siding often has a chalky, oxidized finish. Washing removes dirt and mildew but also removes loose chalk, which can make faded panels look patchy. If the finish is badly oxidized, washing is usually the prep step before repainting.
Avoid: High pressure, which dents thin panels and strips chalky paint unevenly.
How often: Every 1-2 years.

Humid summers in Indiana grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
Much of Indiana has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.
