- On the ground, un-box the skylight and remove the labels from the glass.
- Clean the glass with mild soap and water.
- Put skylight back in box to move it onto the roof.
- As needed, about once a year, clean the skylight with mild soap and water.
- Sweep away any built-up debris around the flashing.
- Do not clean the skylight glass when it is in direct sunlight or on a hot day. Streaks and splotches will be left on the glass and you could be burned.
- Do not use ammonia to clean the skylight; it can damage the coating on the glass.
- Do not leave labels on the glass; they will become cemented on by the sun.
- Do not use a blade or anything abrasive to scrape off old labels or other debris; this could chip the coating on the glass.
Most of the time you won’t need to remove the trim ring once it is installed, but there are a few instances when you might want to know how. Perhaps you want to clean inside the diffuser, or change out your diffuser for a different style, or you want to protect the trim ring when re-painting the ceiling, or maybe you need to change out the light bulb on your light kit.
The trim ring clips into place on the ceiling assembly, so you will need to rotate the trim ring counter-clockwise until the clips line up, and then you will be able to gently pull the trim ring down.
When putting the trim ring back in place, make sure the gasket around the diffuser is not sticking out in places (if it is, just push it back into place), then line up the clips, and twist the trim ring clockwise until it is snug.
Here is a short video that demonstrates removing the trim ring and gasket:
