Cleaning the Inside
Step 1
Remove any dust webs from around the skylight using a broom. Place a dropcloth beneath the skylight and keep it in place until both the interior and exterior are cleaned. Attach a rag to the end of the broom using duct tape.
Step 2
Apply a generous amount of glass cleaner to the rag. Wipe the skylight with the rag. Use a long-handled squeegee to wipe the skylight if it is a flat panel.
Step 3
Dry the skylight using a clean rag. Repeat this cleaning procedure every six months to keep the skylight clean.
Cleaning the Outside
Step 1
Add 1/4 cup of liquid detergent to a bucket and take it up to the outer skylight surface using a sturdy ladder. Add water to the soap with a garden hose.
Step 2
Hose down the skylight with clear water. Spray on a small amount of citrus based cleaner if there is bird excrement or tree sap present.
Step 3
Clean the skylight by scrubbing the surface with the soapy water and sponge. Rinse with the garden hose and allow the surface to air dry.
Step 4
Apply a layer of automotive wax to the skylight and buff with a clean rag. This will protect the surface from scratches and weathering, according to HowtoCleanAnything.com.
