    Evening all, Found 6 tubs of flux but they’ve all expired last year can you still use it or shall I just them away ?

    I've got a jar of Vick's vapour rub that expired in Sep 2005. It still smells minty and it still works.

    I'd use it, the flux that is.

    Tin of Fluxite at college. Gone thick, lid missing and rusty nail in the middle for some reason (the Level 1 students ?).

    Worked very well.

    I don't do plumbing very often so all my flux is at least 10 years old, some of it could be old enough to vote and get married. It all works fine and I haven't noticed any decrease in its performance over the decades.

    Its main purpose is to stop the oxidation so I would have thought it shouldn't matter about shelf life if you think back to lead soldering wipe joints we used to use tallow,

    While we're on about flux - what's the best??
    1) Laco
    2) Powerflow
    3) do you remember that Yorkshire one in the green & white tub - it had a distinctive smell? Is it still available?

    . and how many of you use lead solder where you can i.e. for gas and heating?
    I remember lead solder performing so much better than todays 'lead free' with silver alloyed in :)
