Default Re: Rusted in grub screw.

PlusGas has been my 'go-to' for the last 45 years - the biggest problem I find with it is the tendency of the solvent-component to evaporate from the can whilst in storage. I never seem to use-up a can of the stuff, it escapes into the wild when my back is turned.

The heated-screwdriver-tip is another technique worth remembering: I've got a couple of old screwdrivers here whose tips I'm happy to heat until red-hot in order to put some heat into a tight grubscrew.
