Short answer: clean aluminum frames, glass, tracks, and drainage openings with fresh water, mild soap, and a soft cloth or non-abrasive brush. Avoid steel wool, harsh abrasives, strong acids or alkalis, and unapproved solvents. Coastal and highly polluted locations usually need more frequent freshwater rinsing because salt and deposits can accumulate on finishes and hardware.
Owners should remove track debris, keep weep holes open, wipe standing water, and report loose handles, difficult movement, unusual noise, or damaged seals early. Contractors and facility teams should inspect rollers, hinges, locks, fasteners, gaskets, sealants, glass setting, and perimeter joints on a planned schedule. Designers can improve long-term maintenance by providing safe access, suitable finishes, replaceable hardware, and details that do not trap water.
Do not force a dragging panel or apply random oil to every component. Some hardware requires a specific lubricant, while certain products can attract dirt or damage plastics, seals, or finishes. Follow the system or hardware manufacturer’s instructions, and have heavy, misaligned, or unsafe panels serviced by qualified personnel.
A simple maintenance record with dates, photos, and repairs can help identify recurring problems and support warranty discussions. If you need a project-specific cleaning or inspection plan, send OTEC the window type, finish, age, exposure, and photos.
