Help!! Solid stain over a painted deck

Hi,  I'm had a few boards of my deck replaced last year and am getting ready to paint/stain the whole thing now.  My question is ...Is it ok to put the solid stain over the painted deck.  I don't know what paint it is.    Also, instead of cleaning and brightening my deck for prep, can i use the Wolman Deck Brite to clean it?  What is your favorite solid stain?   Thanks so much!
