Oak tannin stain on patio

We had a new, cream coloured stone patio layed this time last year.

Over the winter, several acorns have fallen onto the patio and left a nasty brown tannin stain that I can't remove - they look pretty ingrained.

I have tried a pressure washer, bleach, white vinegar and bicarbonate of soda, but no joy.

Any other idea's how I can remove these stains?
