I've tried it a few times and have managed it with about 50% success
by dismantling the valve and flushing every thing with acetone
including a few flushes of the exposed valve on the
top of the can.

Only by buying a professional gun. The aerosol cans are one-shot for
me too. With a prof gun, and a can of cleaner, never had a problem.
In fact even without the cleaner, I've left the can on the gun for
three months and it still worked. This is mine:

With gun type cartidges, ali foil has a much better success rate than
clingfilm.

Until you've used one, you'll never understand the difference. You
can stop halfway through a job, go out for a beer or ten, come back
when the hangover has dimmed, and just carry on. None of that cleaning
the little plastic trigger etc..
I never used the nipple guards though.

with acetone after use.
Passed on with no guarantee that it works.

If you can't get acetone then buy gun cleaner but as someone else said
the best way is to buy a gun from Screwfix and a can of cleaner and
you'll have no trouble .

You'll almost certainly pay more for acetone than expanding foam, so
just chuck the part-used can of foam away...

Isnt it bad to use expanding foam to fill electric cable holes,
doesnt it leach the plastic around the wires dangerously?
Shouldnt we use normal caulk for electric wires holes?
surely there's some draughts in the garage or somewhere you can use the rest
of the foam up at?

I bought a can from Wickes last week & it said on the label "ideal for
filling electric cable holes" or words to that effect. IOW it was
reccommended for the job, so I guess it must be fine.

Use the "gun grade" stuff and leave it on the gun. (if you take it off
you can still get the same problem with the cane seeping)

For this application, cellulose thinners works fine. Costs around £11
for 5 litres at a good local car spares shop.

For a small need, try using nail varnish remover, if you can "borrow"
some. I think that's Acetone based.
