My poor little greenhouse is getting old and the roof needs replacing. I have tried to spray it with a bleach mixture and wash thoroughly but now that does not good.

What is a good product to use for roof replacement? (please excuse the mess, I am trying to organize my chaos)

Use full strength bleach, no not add water, it will do better jot of cleaning. I pour 1 gallon of bleach in a 1 gallon weed sprayer. Stray then wait 15 minutes then rinse. That corrugates fiberglass never did last very long for me about 3 or 4 years.
