(calcium: "pirahna solution + acetone", Chemicals & Equipment)
I've learned the hard way that prevention (eg. getting off my lazy ass & cleaning right after the reaction) is worth a pound of cure (what's required in my present situation after the shit has cacked on to the flasks & glassware). I'm begining to think that maybe this is why everyone seems to have such good results with acetone. I mean if used right after the reaction, anything works!
Neo, Acetone has a B.P. of 56. Celcius, make sure your flask has cooled below this Temp.
