Jointex residue - please help

[emsyw]

Hello,
We have just laid a lovely sandstone patio and used jointex easy joint to point it up, however it seems not all of the mix was brushed off the slabs, and now it has dried and left residue/marks. Can anyone tell me how to remove them, or if they will simply remove in time?
Many thanks

not a long time either ,just let the weather do its work
