    Mix 1 gal Distilled water with 1 bottle of "Heet".. it's methanol, and the same difference, but surely somewhere in your area sells premixed -20 if you need it.

    1000 ml water
    30 ml white vinegar (or 30 ml 5% acetic acid)
    4 ml liquid dish soap
    60 ml isopropanol (or rubbing alcohol)

    Do two things in parallel: test first overnight on a non-visible area so you know it won't damage your paint; also leave the bottle outside overnight so you know you have enough isopropanol in the mix to prevent freezing. Then act accordingly. If your climate is cold enough you can simply test the bottle in your freezer, which with any luck should be around -20C anyway.

    Not responsible for any damages or injuries. You do this at your own risk.

    BTW, if you want to know the actual contents of the Subaru stuff, contact Subaru and ask for the MSDS. It may not have proportions but it will have contents.
