I have a pressure treated deck coming up on one year old this June. I am ordering pecan twp100. I like the colour it is on the already greying wood (tested), but not on a fresher greener scrap pc I tried. If I use a cleaner/brightener now will the finished stained wood look a different colour cleaned vs uncleaned? I guess what I am asking is will the restore a deck kit bring out the green pressure treat colour again? Also do I need to use restore-a-deck or can I go with a big box brand?
You should use the Gemini Kit for prep. The kit does not bring out the green but restores the wood to it's natural color. If your wood is green internally then there is nothing you can do about that.
