chalk is great- sometimes.

if the wood is getting painted or is being left raw no problem.
however, I have had ghost marks of the chalk show up after stain and
especially after waterborne clearcoats. I no longer use chalk as a
marker on interior finish work.

I use chalk mostly to indicate orientation of pieces (stock) and to mark out
bisquits, and I once had the problem of not being able to get rid of some blue
chalk in the finishing process, it had insinuated itself into the grain
somehow.

Compressed air and a dust gun have proved to be the best way of removing it,
just prior to pre-finish. No more probs.
