yes.
The process seems to work better if you pour a couple ounces and let settle
and then pour the rest. 10 ounces per can is correct.

You should! easy to do with simple procautions.
maybe you might ad a few precautions to the method Jim?
I always hate to post a simple method using simple methods. especially after
the BEE-L issue over using oxalic acid dribble which those which have used
see as fairly safe mix and to use.
Keeping away from eyes , breathing and off skin with all chemicals is
important. Even apistan, checkmite , apiguard,apilife var, menthol , formic
acid etc.
