Hi MF,

I'd pretty safely say that it won't work on an already blocked can.

Because that would've gone hard halfway up the pick up feeder tube.

Also I've thrown out all the blocked cans now so can't really experiment with one of those. Maybe B_S could have a crack with one of his cans still laying around.

Cheers,
BB.

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
