For the advice Celeste. I find myself spending a lot of my free time either online or in the local hardware stores reading bottles and getting to know the different product names and what not. I had an interesting local guy tell me something the other day about cleaning decks. He said that he had a local pressure washer a few years back (no longer in business) that would swear by generic draino to clean decks. I forget the name of the product but he said for some reason it worked wonder on cleaning and brightening decks. Ever heard of this type of thing or is this the reason why he is no longer in business?
