We have a brand new paver stone walkway/patio. To my dismay, I noticed that their were leaf and acorn stains from the oak tree in the front yard. I've learned my lesson and I'm going to try to keep the walkway swept more regularly.
Will these stains go away with enough rain & time? If not, what's the best remedy for removing these stains? What's the best mode of prevention?

The tannins from oak leaves will leave stains behind. I would suggest not worrying about it. Those stains are just character, part of nature. Choose to appreciate nature.
You could probably bleach them out (using simple chlorine bleach or oxalic acid), but why? Why introduce harmful chemicals into the area that may hurt you or damage your plants? Besides, the bleach may not get everything consistently the same color as it was. So you may just leave yourself with another problem to solve.
Sunlight will cause them to fade over time anyway, and as other stains occur, the pavers will become randomly stained, eventually all to the same color.
