ok, this isnt too "advanced" of a question but i didnt want to clog up other areas of the forum with this.
whats the best for cleaning optics? isopropyl alcohol? acetone? or methyl alcohol? or none of the above?
i have PLENTY of the cloth tipped q-tips and actual optic grade cleaning aparatus. (it helps when your pops makes medical grade fiber optics for endoscopes!!!

) but they deal with some pretty nasty chemicals. i *THINK* for industrial laser optics (scanner mirrors, dichros, beam steer mirrors) ipa alcohol??
thanks
