Anybody with experience in cleaning stains from rotting leaves left on
the fiber reinforced driveway?

I tried 1800 PSI power wash - did not help.
I tried steel brush with soap - did not work.

What would be the best way to remove them ?

Pszemol.

imho:

I found only with time they fade. The tannins seem to penitrate deep
and only sunlight seems to fade them.

Now this is me, I can tollerate them, knowing that they will dissapear
with time. Each fall, my driveway looks like some modern art.

You need to etch the concrete. Use hydrochloric acid or muratic acid
and wash it down. You can usually find directions on how to do an acid
wash if you look for directions on how to prep concrete for painting.
Warning: Be prepared to do the whole thing. Test a small area first and
see how it blends in. The area that is acid washed will be nice and
white.

Good Luck

I'd try one of the concrete cleaner products available at any of the
home center stores. Usually found in the driveway sealer section.

I would not etch with acid for this but etching will make it rougher
and less slippery, a benefit. Bleach and a powerwash should do it, but
just bleach might be enough, use a garden sprayer.

Seems an organic stain should come off with bleach. Tried that?

Don't remove them. Eventually the stains will weather away. In the
meantime, enjoy nature's patterns. Move the leaves to a compost pile.

Oxalic acid is used to remove stains in woods high in tannins and if
the stains are from tannins, ... Wood Bleach is oxalic acid and not
expensive, try paint store. Check the ingredients to ensure it is
oxalic. Barkeepers Friend also contains oxalic but may have other
ingredients also. Don't breath the oxalic dust.
