Just use normal wood decking —————————————————— (Wood cedar / treated) Pros Easier to repair -Can refinish to a different color at a later date -Has options for hidden fastener (camo is the name I think) -Stain or paint yourself/ contractor so no issues with finish -Cheaper than “composite” decking even if you decide to do cedar -Has a warranty Cons -Can rot, split, warp -Maintenance restaining or sealing —————————————————— (Composite decking “Ultradeck”) Pros -according to menards should not split crack or warp (seems like it does do this a lot though) -pre finished -Has a warranty Cons -Expensive -Often has issues with finish -Hard/ impossible to touch up if decking gets scratched or scraped -Often cracks splits warps (sometimes issue gets resolved) -Will fade (Color will fade in first month) which makes a replacement board look a different color down the road -Wood based composite up to 50% real wood —————————————————— Feel free to add any other pros or cons you think missed

I love my composite steps because they are not slippery in the winter like wood. But there are necessarily gaps in the composite between the boards so mosquitos and other insects can get in if its used on a porch. So I don't understand the logic of using this for screened porch floors. My dh can attest to the fact that mosquitos go under porches from when he had to do some work under the porch last summer. Dh put some drainage holes/tubes in our existing upstairs screen porch. He can actually close them off with little pieces of chopstick. Helps when we do spring clean up (with mop like indoors.) He has a plan for downstairs too, but not sure exactly what it is. It seems like you could put some thing in for drainage that could be closed up most the time (a hatch comes to mind), Kathy

Timber Tech would be m vote with Correct Deck CX second but that is just my opinion.

Wash it? We had a composite deck in our last house and organic material got in the grooves and there were parts that got a bit mossy. They do sell cleaners for vinyl siding. You could kill two birds with one stone. Use a power washer and it will be quicker.
