Vacuum dirt and debris from sill and track areas before washing
Clean glass and window or door frame with a mixture of mild dish soap and water. Rinse completely with clean water and wipe dry with a soft cloth to avoid water spots.
Avoid washing glass in direct sunlight.
Never use abrasive or caustic cleaners. They can cause permanent damage to the frame finish or the glass.
Mild, nonabrasive soaps are usually the safest for most dirt and stain removal, but any cleaner you use should be tested in an inconspicuous area first.
Always rinse completely with clear water and wipe dry if possible.
Check to make sure drainage or "weep" holes are always clear of dirt and obstructions – both inside and outside the window or door in the bottom of the frame. Composite windows do not have weep holes. Note: If the window is "stacked," there may be weep holes between units.
Clean screens by removing them, washing them on a flat, clean surface with mild soap and water and a soft brush. Then rinse, wipe dry and reinstall.
Windows and doors with moving parts include hardware components that should be lubricated periodically. In salt-air environments, these components require monthly lubrication.
After wiping clean, use a silicone spray with a non-petroleum-based propellant on door or sliding window tracks, rollers and locking hardware
