Removing harden glue form barrel

[sidelever]

Have been asked to clean a gun easily enough I thought.
It has had camo tape along the barrel and silencer and it had been there for some years.
The tape came off ok but it has left the harden glue residue.
Any ideas how to remove this crust without damaging the blueing?
Cheers Sidelever

Try softening it up with a hair dryer, heat gun might be too brutal, roll it off when soft, we used to do this with car stickers. Be wary with solvents, should be ok on decent bluing, but painted surfaces depend on what's been used, try small bit outta sight first

Acetone(nail varnish remover)make sure it's pure with no additives.

As above. Worked well when i used it inntge past.

As it's hardened do no use heat , Acetone or MEK will soften it enough for you to wipe it off , Nail varnish remover normaly is Acetone with something like Lanolin added , Use that as it is the solvent acting on softening the residual glue so you can wipe it off , wrap it in paper towel's and drizzle the solvent on to the towels and leave for 10 min and then wipe off.

Depends a bit on what the composition of the adhesive is. Acetone, MEK are worth trying, iso propanol might be worth trying too. I've had success with white spirit & also that very popular spray lubricant **40. As has been said try to leave it on to soften, the paper towel trick works well but some solvents evaporate very quickly, especially in the warm weather, watch out for fumes/ flammability, avoid the vapours & be aware of the H& S issues, some are nasty chemicals......

Be extremely careful if you use MEK, as it's known to be carcinogenic.

Another vote for "pure" acetone - not nail polish remover as it often has softeners and other crap in it

In order of potential hazard. Try WD40 first, then paraffin then petrol and then cellulose thinners or acetone or MEK. One of those should shift it.

wd 40 .

Many thanks to all who replied.
I’ll start with the safest one **40 hopefully that will work before I need to use MEK.
I know that is whiffy stuff they use it at work cleaning aircraft surfaces.

I use Parker Hale 009 Spray and 000 Wire Wool, works perfectly

Petroleum jelly otherwise known as Vasaline is worth a try.
Give the said area a liberal coating and leave for a few hours.
