Yo Ken, if your still around your up on this one. Far as Composites go I am with the Larry/whoever We are for the most part. Composites are really no longer using recycled material because there is just not enough of it so most of the raw stuff is virgin,the energy used to make composite is an enviro no no, when its time to remove the project composite is not real big on bio degrade its tricky to burn shreading it would be silly. Bottom line composites are not so enviro freindly. Info like that might suggest its not all that good to clean it either, with anything. I dont agree>> composites will out last Ipe, left to go silver/gray Ipe is as close to no maintance as a person can get. With the softer composites like Choice/MoistureShield even trex= tjunk I have found a coat or two of TWP 116 seals up the decking,locks in the color and keeps mold,mildew,stains from causing major problems. Of course not needing to do this is the reason the Wallet goes for composite in the first place. I my own self dont like composites at all for the reasons stated in several posts here and on other sites. Welcome aboard Larry!!! Sorry I dident understand your intent at the begining . John

We put down a trex deck on east side of our home with lots of shade 3 years ago. No problems with mold until we had a very wet spring and summer in minnesota this year. I expected to have to wash and maintain this low maintenance deck. We had lots of mold staining everywhere on deck. After tring Behr deck mold and remover with no luck I was extremely unhappy. Tried Simplying Green full strength with no luck. After pulling out my hair and complaining to my husband about why he wanted composite instead of wood I told him I would have been better off spending 2 days staining a real wood deck. After lots of reading on various threads on composite decking problems and trex websites on how to clean it,I finally found a product that working amazing! I used Mold Armour ez deck wash from Home Depot. I know the product contains a bleach solution but it worked in a matter of min. I did wet down the surrounding areas with a water hose including the railings and grass. Wet down the deck boards first before applying the product with a soft brush in an ice cream pail. No scrubbing was required but I had control with application by this method. I did small section at a time and rinsed off after only 5 min or so. You can see the product work! Be careful not to let solution on boards to long because it does contain bleach and bleach will fade anything it comes in contact with. I did this project on July 4 and want to see how long mold stays away. I plan on buying a more eco friendly product in future like Corte Clean but didnlt try it this time because no stores in our area carry it and it is quite expensive. You also have to watch expiration date and have to buy it on line. Has anyone had luck with this product with mold spots and how long does the mold stay away with Corte Clean or Mold Armour? By the way my deck looks amazing and has no structure problems like some I have been hearing about. My husband built deck himself and followed all the proper guidllines to install. We also used hidden fastener system for instalation and used proper support system underneath. We have the saddle color with accents brand. Hopefully the mold issue will be a controllable one since we plan on staying ahead of it this time and not wait so long to wash it. We also had alot of snow this winter and I didnt always get out there to promply to remove snow. Let me know if you have had better luck with other products as I dont want to use a product so often that contains bleaching agents. Still wish my husband would have agreed with me to use cedar but I lost the battle and had to settle for composite. I keep telling him I told you so about composite and I am stuck with an $8,000 deck that is not low maintenance. I appreciate any feedback on a sealer or something to put down so i only have to wash deck to maintain and keep mold spots at bay. Any luck with sealers or stains?

Epoch/evergrain, one of the soft composites like choice or moisture sheild same kinda deal sister joists on any butt joints, pron to mold unless they get a finsh on them,not near the complaints as trex. Some say a shaded area promotes mold and mildew. With all the composites a person needs to understand completly how and when they want it installed read the fine print on instalation. Provide cross vintalation. I see you have already ruled out Ipe so I wont go into that. I have one Epohc project out 3 years the color has faded 30 % or so not a lot of mold really just the normal stuff that will happen to any outdoor project left alone with no care at all. Also one choice comerical job on a multi leveal condo its 5 years out and looks really bad the decking has faded to a liver color and has started to degrade. One thing might be of intrest to ya, I used the cut offs from that choice project for the treads on my own upstairs deck stairway I put two coats of twp 116 finish on them that same 5 years ago they look a lot better with no real sigh of degrading.

I'd get an outdoor mat for the deck and an indoor washable mat for just inside the door. Then see if the leaves and dirt stay on the mats, not on the rug you have already.
