How to Free Up an Aluminum Window Frame Handle

Clean loose debris from the moving parts of the handle with a dry paint brush. Shake the can of penetrating oil, according to the manufacturer's directions. Attach the applicator tube to the nozzle of the oil can. Spray penetrating oil into the moving parts of the handle or locking mechanism. Wait a few minutes for the penetrating oil to saturate the corroded surfaces.

Try to turn the handle manually. If it won't budge, apply more penetrating oil. After a couple more minutes, try again to turn the handle manually. If the handle begins to move, wiggle it back and forth to loosen it. If the handle is still fused, drape a cloth over the handle to protect its outer finish. Gently tap the handle with a mallet to break the bond between corroded surfaces. Once the handle begins to loosen, you can work on making it move smoothly.

Remove the handle by unscrewing the central screw in the pivoting portion of the handle. Once the handle has been removed, clean the articulating parts with aluminum cleaner. Pour about a teaspoon of the cleaner onto a rag. Wipe the cleaner onto the pivoting components of the handle. Rub the cleaner into the aluminum. After a minute or two you will see the chalky film disappear and feel the surface becoming smoother. The aluminum cleaner will also help to prevent future corrosion.

Reassemble the handle and screw it in place.
