Thank you for the reply. I think I will give the wheelguard a quick soak and see what happens. If I lose any decals, those are small then I'll know if I can use the kerosene on the body of the machine. I assume kerosene will work in cold temps. I really don't want to use anything flammable in the house in this weather. The kitchen is too close to the laundry room with its pilot lights. I used Dawn and more SM oil tonight and I can see a glimmer of decals under the tarry junk.
