Is there a good way to clean and maintain greenhouse plastic?
I’ve been using my greenhouse for a while now, and I'm starting to notice some dirt and residue building up on the plastic. I want to keep it clean to ensure maximum light penetration and efficiency, but I’m not sure how to do it without causing damage. I've read a few conflicting methods, and I don’t want to ruin the plastic. How do I safely clean and maintain the greenhouse plastic, especially with our weather here in Toronto? Any recommendations would be greatly appreciated!
