Welcome to the forum Whitby.
Blast cleaning is not recommended. I haven't tried it myself, but those who have suggest it leaves the beams looking like driftwood. Are the white deposits limewash? if so, they will be almost chalky in texture, and will be stained with whatever came into contact with them in the last hundred years. Limewash will wash off with water; use a soft scrubbing brush to get into any crevices.
How easily the varnish will come off depends on the surface texture of the wood. I'll leave it to others on this forum more expert to suggest ways of removing it without damaging the timber.

I've used Kling Strip on my beams and it works a treat, damn hard work, but so rewarding.

Many thanks for the responses, I will try the kling strip on the varnish, the white does appear to be lime so I will give the hot water and scrubbing brush a try.

Or simply re-limewash them all?

Will limewash take on varnish?

Distemper should, if limewash doesn't. It may do with a good wash down and sand.
Suck it and see .
