Don't have any around, but, yes, think you're right--should be methylene
chloride. I stand corrected (not the first time (!)). And, as the
previous posts mentioned, it is caustic, so gloves would be a very
proper precaution, as well as adequate ventilation would be, which
almost goes without saying these days with chemicals of all sorts.
However, to suggest that it is extremely dangerous to use might
over-state the case. It is commonly available, and if one follows the
precautions for use, there shouldn't be any reason that it can't be used
with care. Given the above, which I certainly don't challenge in any
way, if one has a heart problem, or has any doubts about health effects,
it would certainly be simpler to hand the manifold over to a local
machine shop to have it bead-blasted, rather than take a chance with
fumes.
Cheers.
