Acetone will do it.

Remember your lock will need re-oiling afterwards.

Seconding this. Acetone doesn't mess around. Squirt some WD40 after.

>>3472

WD40 is shit, GT85 is the real deal.

>>3473
British oil for British locks!

>>3474

WD40 is not oil, it's water based. Hence, shit.

Would Nail Polish Remover do the job?

>>3476
Yes, it's essentially acetone.

Also WD40 is fine, stop being princesses.

>>3477
Stop supporting American mercantilism over our industries.

WD40 is shit at doing the job it is meant for, displacing water and destroying rust, because it's a water based product for light household use.

Any mechanic worth their salt uses GT85. Don't trust a man's spanners unless he has a rubber mallet in his tool box either.

>>3479
Not sure where you're getting 'water based' from for WD40, but you're wrong.
It's a bunch of light oils (too light to be much use as lubricants, good for washing existing lubricants out of places) and a bit of something viscous and oily to leave a residue once the light stuff evaporates away (hence water displacing).

>Don't trust a man's spanners unless he has a rubber mallet in his tool box either.

Is that a euphemism?

>>3481
Yes. Don't catch the gift.

>>3474
May I take this opportunity to point out the car in OP's picture is a Mustang - an American car.

This. WD-40 was invented during WWII for weapon and machinery maintenance especially in adverse conditions. It is a light oil that is good at dissolving rust and grease-based dirt, but as a light and volatile oil, it tends to be quite poor at keeping moving parts lubricated permanently.

You should also never use WD-40 on things like motorbike or bicycle chains, because it can remove a chain's inner lubrication which, once washed out, is very difficult to replenish.
