Removing superglue from plastic spectacle lenses
 

Hi Folks,

Eldest daughter has managed to get superglue all over one lense of
her glasses. (Whilst wearing them, tidying up , at least it's not
in her eye)

Some came off fairly easily with IPA, but still plenty on there,
and tips for cleaning it off. At the moment they are soaking in
some warm soapy water to hopefully soften the glue.

Not the end of the world if we can't get it off, she is due an
Opticians appt, and would probably get new ones then anyway, she
has her old ones as spares.

Thanks

I've heard of an industrial solvant callbed PBC or soemthing similar,
on asking about it I found that the best place to buy it was in a gay club because it can be used as a drug and quite expensive and limited to industrail use, so never managed to get any to try out.

I'm pretty sure that in casualty they just use warm water and soap (or
detergent) to remove it from skin. The usual lens material is a
thermosetting resin known as CR-39 and with any luck won't be
"dissolved" by liquid cyanoacrylate, but I would be inclined to give it
plenty of time and not too much mechanical force.

The company loctite used to produce an unsupergluer in a little bottle at
huge expense as i recall. It smelt foul, a bit like rotting cabbage.

Only things that work are acetone and nitromethane and if its plastic
lenses chances are both will dissolve those, too.

Neither are easy to come by. Acetone (not MEK/dellulose thinners) is
usually available f6omn specialist glass fibre suppliers.

Commercial superglue debonders have that and a nitromethane gel in them

Doesn't work. I've had more superglue on my skin and clohese than most
people have had hot dinners.

Nothing touches it except an angle grinder or acetone

Last time I needed some acetone I just bought nail varnish remover from
Superdrug. May not be 100% pure but it dissolved whatever it was I
wanted gone.

But I agree it could well dissolve the lenses too.

Ah yes acetone is available as nail varnish remover at the same price
for 10cc that I pay for a litre..

Foam-gun cleaner is usually acetone.

Your metric was "easy to come by" and I felt that for anyone dealing
with superglue a bottle of nail varnish remover would do.

But JOOI, Superdrug sold me 50ml for 79p; so where please do you get a
litre of acetone for 16p? Or even for 79p?

But your 50ml bottle did not contain 50ml of acetone, most of it was water.
I pay about £15 for 5l of pure acetone, use it for cleaning steel prior
to tig welding.

Fair cop 'guv

Before going to Superdrug I tried the nearby wholesaler which supplies
salons and nailbars but they couldn 't offer me anything smaller than 5l
for £12+VAT :)

'nail varnish remover' from the chemists shop is usually acetone with a

nitromethane may be available from firms who sell model aircraft fuel

I've not found it hard to buy acetone/. IIRC, our village chemists
sells small bottles of neat acetone, as well as nail varnish remover.

Anyway, soaking in warm soapy water a lot, and cleaning what I could off
removed enough so that the glasses were wearable, if rather annoying.

I was in Toolstation today, and so bought a bottle of superglue
debonder, and will see how that goes

Yup, and that would be very expensive nail varnish remover.

My neighbour was, for some reason, throwing out nail varnish remover, so of
course I took it in case it came in useful. It has some sort of
'conditioner' in it, so for some uses it would need cleaning off; for other
purposes it might be useless.
