'Fraid I've never used Trefolex. I was taught to wipe taps through a pot of
common-or-garden tallow before use, but must admit that I tend to drip a bit
of liquid tapping oil on instead.

I have to confess the smell of hot tallow is something which I was
glad to forget.
A bit of pure lard oil on the chips- the Myford ones, has to be
encouraged.
I keep giggling about the old air aces of WW1 who got the full blast
of castor oil as they went into action. Sorry, fellas, got carried
away.Oh, sh1t

Cheers

Just a bit of googling will get you the Safety data sheet:
http://www.warrenbestobell.co.uk/PDFs/trefolex/06PTREF.pdf
on it conditions to avoid are HEAT!
caution highly flammable and toxic vapors produced!
dont think Id be heating it, YMMV.

You could try just pushing it through a metal sieve, my tin is
'squishy' enough that
this might work.

If you do heat it do it outside, not over a naked flame and let us
know how it goes.

Methanol/ethanol 1% when new and the lid shut!
What now in the real world?

Tallow as a wiping agent for plumbing. Petroleum jelly taken in all
sorts of orifices- and out. Maybe piles of problems here.
You know, I could think of lots more hazardous things- like people.
Let's get into the real world. Heat the bloody stuff up- or spend
money- that dirty stuff that every Tom, Dick and Harry has had their
hands- and perhaps a few more things- on.

Medical opinion is now in favour of a child eating a peck of dirt at
nursery or play school- as a preparation for future life.

I've got to damned near 78- and I have ingested all sorts of things in
that time.

Next?

I don't think you would have to heat it enough to be dangerous, for it
to become fairly liquid. ISTR it goes quite runny just left out in the
hot sun.
