Yes, spontaneous combustion risk is real, but it can be avoided easily enough —

I keep a piece of cut off T-shirt submerged in the mix as an applicator, and the
mix & applicator are closed up and stored at all times inside a glass flip-top
storage jar that incorporates a rubber gasket seal and wire cam-lock closure.
Similar to the old Ball canning jars, but with a simpler wire closure mechanism.

My jars are made by either ‘Fido’ or ‘Luminarc’, and they have worked very
nicely for a good 15 years, maybe more.  I also substitute terps for the paint
thinner, but the terps does tend to slowly escape through the seal over time.
That has to be topped up periodically  — maybe twice a year — to re-liquefy the
mix before use.  I suppose oxygen might also manage to diffuse through the seal
into the jar if the partial pressures are unequal, but I can’t visualize what
would cause that as the mix isn’t going to oxidize while sealed.  Whatever
migration happens, it sure isn’t going to be very quickly or any substantial
quantity until the jar is opened for use, and where you choose to open it and
use it is up to you.

The results with Tony’s mix are always the soft feel and cleaner look of an old
tool, accomplished without destroying the patina.
