No and Yes.  I can smell the isopropanol and acetone but not the acetic
acid so it must be quite dilute.  By the way, the stuff is "Lens Cleaner"
from American Scientific Products Cat#:  M6015.  There may be another
digit or so in the cat # since the stuff inside the bottle is so good that
a past spill took some of the ink off the outside of the bottle.

I presume the brand doesn't much matter since it's more fun to cook up
your own?
