Can you recommend an effective product for removing dirt from aluminum storefront window frames?


Use a mild detergent solution applied with a window brush or a white scrubbing pad. If you have access to a pressure washer or vapor cleaner, that too, will lessen your time. Just be sure to turn down the pressure (300 PSI) and keep the nozzle back from the glass at least 12 inches or you could damage the seal around the glass and get water inside the space.
If this doesn't work specialty aluminum cleaning products and course pads are available, however, they are very strong and abrasive and may damage the aluminum if specific procedures aren't followed closely. If you use these products, read and follow the directions exactly, test first in a small spot or you may damage the frame, exterior building surface and your hands or eyes. Rinse well and wear your PPE (personal protective equipment). In either case, after the frames are clean, the windows will squeegee clean easily.
