Cleaning a skylight
Q. I have a skylight that on the outside is full of sap and dirt. What’s the best product to use to clean it? Thank you.
A. Try washing the glass with warm water to which ammonia has been added.
Be careful walking on the roof or, better, have a contractor or handy person experience in walking on roofs do it for you.by
