Nothing to do with gardening - stuck bottle top.

Does anyone know how to get the top off an old bottle of watercolour masking fluid?
Hot water? Solvent? Something else?
The bottle is almost full and the contents look ok.
In London. Keen but lazy.

    I'd try standing it upside down in a bowl of boiling water.

    Failing that a pair of pliers.

    Maybe both?

    Will try the boiling water. Pliers on their own haven't worked.
    I assumed it was some form of plastic. That's why I wondered about a solvent.
    Thanks @Dovefromabove

    So far as I remember, from my painting days (which were in about the 18th century), masking fluid was a sort of rubbery material?

    Maybe put the bottle into the freezer for a bit to make the stuff in the cap more brittle, then tap it all round the top with a smallish hammer?

    Think it's latex ...

    Just checked ... my bottles all say 'natural rubber latex'.

    If it's a screw top, try wrapping a thick rubber band round it so you can get a firmer grip.  The ones postmen drop on the pavement are just the job.  Lots of firms that sell mobility aids sell a small sheet of thin rubber you can keep in a drawer for just this purpose.  I find mine very useful.

    @B3 -- don't know what kind of bottle you have , but if it's so old that the bottle top label has worn off ... only one i ever saw many moons ago had a safety cap ( glass bottle , and one of those childproof caps that require you to press down hard before unscrewing a bit like the cough mixture bottles ) -- sorry if that's stating the obvious , but I'd try that ( perhaps pre and post hot water immersion) , and before resorting to pliers?
    Kindness is always the right choice.
