Need advise on staining a outdoor deck made of Cambara. Probably not spelt correctly? Anyway power washed the deck yesterday and typically you see blotchy areas were the power washer cleaned deeper and some areas were the wood is naturally darker. My GOAL with this project is to stain the deck and bring back the natural colors. I have used Sikens in the past on new decks would that be a good choice on a deck that is approx. 10 years old?? Thanks
