Have seen quite a few topics concerning ways to keep the sunlight and heat from entering the skylight above the shower. My question revolves around cleaning of the outside shell of the skylight. Mine has turned a light brown and getting to the point of not being transparent. Suggestions welcome as we love camping in the Great Pacific Northwest and welcome the light coming through seeing we're mostly parked under trees anyway. With the exception of the last two weeks we usually don't get a lot of scorching days up here.
