[pugeled]

i would not bother with trying to remove it I have seen the result of trying to remove it and it NEVER works there are allways spots that wont
clean up and when you seal it with clear sealer it looks shocking trust me! plus the pain and suffering of trying to remove it YOU will regret
trying, i would be inclined to buy new decking boards a little at a time
and replace them bit by bit at your own pace and seal as you go the result will a good deck that will last forever, and YOU done it (way to go)
