Deacidifying charcoal drawings

I am a young paper restorer and I'm searching for a proven method of
deacidification of charcoal drawings. I've read through many works
on deacidification but most "classical" methods consist of bathing
the paper in the solution and "my" charcoal drawings are fragile and
cannot be bathed. I was wondering if some more experienced
colleagues have come across this problem in their work and what the
reasonable solution could be.

I wonder if a contact washing with a blotter paper moistened with a
buffer solution would be an option, or spraying? I have heard about
the Wei T'o method but has anyone used this for art drawings? What
were your results? Is the method commercialised in Europe?
