I've been looking into making or buying a boom tent or sunshade to help keep our deck cleaner. We have issues with birds pooping and yes, we have many things in place to try to scare them away so I'd prefer to not discuss those in this thread. I'm wondering how effective boom tents are at keeping decks clean. I've also found a sunshade of the correct size for a mere $40 but I'm curious if having something that's a tightly woven mesh would be less effective than a solid piece of fabric
