I have been doing some hunting this last week and the temps are well below freezing (10 to -10). I would like to clean my gun before driving two hours home, but my solvent is freezing.

What can I use to clean with in these temps? I thought about leaving the charge in it, but my car warms up obvouisly on the drive home and I am very anal about doing this as I don't want to chance a blown opportunity.

I guess worse case scenario is I keep cleaning when I get home.
