Removing CA Glue From Plastic Lenses

[Woodtrnr]

What can be used to remove CA glue from plastic eyeglass lenses without damaging them?

Any solvent I've found that will cut the CA will also dissolve the face mask. The best solution I've found is to take a fresh razor blade (gotta be fresh, tiny nicks on the blade with make big scratches) and lightly shave off the drops of CA (blade flat on the mask and scrape lightly). Then buff the face mask using a bealle type system. Triple E and White Diamond do a nice job cleaning it off.

CA removal

several months ago I read on another site using acetone to remove CA. I checked with my lense maker and he said it would be safe. I then tried it on an older pair of plastic lensenes and it worked It would be best to be more careful in the first place so this did not happen, but we are all human. At least all my problems have delt with clear and not the black.

Tried acetone on my newer face mask and got a nice foggy spot. Urk. Hopefully this is cause it was a relative cheapo. Make sure and do it way over to the edge on a clear spot to check it first.

I would say to use the acetone lightly , first , then to use plastic scratch remover or a Beall system to polish it up.

I have heard that the white diamond is the way to go. It did a pretty good job on one of my face shields. There is still a big CA or old sap spot on it that was too thick. A razor blade would work in cleaning it off.

I've found that the razor cleans it off nicely with only minor scratches (if used gently) and that the buff takes the scratches right out.

Side Tracked???

Gents,

It appears that this thread may have got a bit sidetracked. I think the original question had to do with removing CA from prescription eyeglasses with plastic lenses, not face shields or safety glasses/goggles.

Since eyeglases are made from various kinds of "plastics", but may also have different coatings applied, it would seem best if "Woodtrnr" would contact his provider, inquire there, and, if necessary, have his glasses professionally cleaned.

You would most definately not use buffing compound on $2-400 worth of lenses under any circumstances! 😱

Well, seeing as that is the case (I checked too), vat da heck er ya doin working on the lathe without a face shield? Glasses might be great for little bits o stuff flying straight at you but they won't do much for CA all over your face or chunks trying to take your nose off. They also don't work to well for streams of stuff as chips have a lovely habit of bouncing off cheeks and into eyes.

Safety first! (god, that sounds so trite but it's true)

CA glue removal from glasses

I used to take mine in to my Kaiser Permanente optician who would clean them right up. I asked him what he used and he said Acetone. I now do my own cleaning with Acetone with no problems.......Ralph

CA glue on plastic glasses

I was always reluctant to use acetone on my plastic lenses. Acetone will definitely etch the plastic on faceplates. For my plastic lenses I find that the debonder, supplied by most CA suppliers, works quite well.

And if you don't have a buffing system, what are the other options. Would a rag with white tripoli on it work as well?
