Wow, I didn't expect to generate all this by posing the best etchant
question but I did learn a lot from it. The bottom line is treat it like
any other chemical that is highly dangerous and be careful and safe and
all should be ok. I will etch outside, wear eye protection and work
upwind when possible and not breathe the fumes. And of course I won't
get any on me. Common sense is the key. But I am still glad I asked. :)
Also, some interesting reading on the DHMO.
Thanks,
Dave
