Default Dyson blocked cyclones

My niece has asked me to "fix" her newish Dysaon DC54 which seems to
be suffering from too high a pressure drop across the canister which
is triggering some sort of shut off valve in the motor unit.

It was used to clean up some plaster, whether spilled fresh or
sandings I don't know.

I'll drag a cmpressed air line out and back flush each cyclone I can
see a spout for (42) but if that fails is there a chemical that will
dissolve plaster (calcium sulphate). I don't think brick acid will
work as it is weaker than sulphuric acid that would form the sulphate from
chalk.
How soluble is set plaster?

Take the hose off and remove the blockage.
