-The rain does most of the cleaning duty but every 3-4 years, we do power wash it. -It also comes in other transparent shades like a smoky brown, gray, etc. -No, it does not get any hotter under here! -We wanted the sun light while also offering rain protection & some shade. So we laid some of the pergola planks flat to offer more shade. -It’s extremely sturdy & if installed correctly, will hold up in high rains & no leaking when it rains! Let me know if you have any other questions! LTKStyleTip LTKFindsUnder50 LTKHome
