Stains on pavers

I just finished power washing my patio made of paver stones. During the late Fall and Winter leaves accumulated behind my storage bin and patio table storage area and left large dark stains. I thought the power washer would take it off but it didn't even touch them.
Any suggestion as how to remove these stains?

If you used an electric pressure washer, that's your problem. A gasoline pressure washer with a red tip, should do the trick.

I would try a mild to moderate strength bleach solution. A powerful pressure washing will probably do it but start with the tip further away from the pavers and work closer gradually. You don't want to damage the pavers just to remove a stain.

I have a gas powered pressure washer. And even up close the stains won't budge. A surprising the hi-powered tip does not etch the stone like it might with concrete.

I was going to try the bleach idea but my wife says no that it will leave a worse stain. Other suggested a solution of something like vinegar. I might have to buy a commercial cleaner of some sort. I think Jo-Max makes something for this or maybe Thompson's might have something. I'll check the store when I go to work on Monday.

Try some Muriatic Acid on one paver.

Good thought. I'll try that one paver that won't show too much.

Bleach might work but you don't want to pour it on straight out of the jug. I'd cut it in half with water. TSP is stout detergent that might also help. I'd apply the cleaner and scrub it using an old broom or maybe an acid brush and then rinse with a PWer.
