Berry stains on indian sandstone

[newbuyer17]

I've a couple of unsightly red stains on our patio where birds have obviously dropped fruit. I removed the offending berry and hosed down with a hosepipe but the stone seems to have absorbed the red dye. Rubbing makes no difference either. I've yet to try pressure washing but dont think it will make any difference anyway.

The slabs do seem to absorb moisture a lot. When it rains you can almost literally see the water being absorbed via the slab and it drys very quickly. I'm assuming that the dye has been sucked in - is this normal and is there anything that can be done about it?

On a seperate note, given the porous nature of the slabs, would I suffer from picture framing if I mortar pointed if/when my geofix pointing fails?

Also, should I have sealed these slabs with anything to avoid this sort of thing?

Has nobody any ideas? I'm starting to get a bit desperate here. Another couple of ink-link stains on the patio. The birds are clearly eating a lot of this somewhere and then leaving droppings all over the patio. It looks like it is being absorbed right in - almost like ink on blotting paper.

A jet wash did nothing so I'm back to applying some form of chemical. I've read the general stains page. Nothing for berries in particular, but which of the substances could be worth a go with minimal risk of doing even more damage to these porous indian sandstone slabs?

I'd rather apply sooner rather than late.
Thanks

If anyone knows how to deal with this, Roger from R and A pressure washing will know. He is a regular member here - take a look through the various threads - you'll find him easily.
