What would be the best method to get white emulsion off rough split
sandstone and the mortar (cement not lime) joints? The wanted end
result being visible clean stone and mortar. There is only about 1 sq
metre to do, indoors.

Thinking of a steam cleaner to soften the paint but how to remove the
softened paint totally from the gain of the stone? Indoors, so
sloshing lots of water about isn't on.

Mechanical with a needle gun?

Any other ideas?

I used a circular metal sanding disk on some window sills that we had. You have to be very careful not to go into the stone but it gives a nice smooth finish.

Wish to retain the rough split (across the bedding planes) nature of
the stones.
