>> At Home Cheapo you will find gallon cans of Methyl Ethyl Ketone, quart
>cans of Acetone, of Toluol or Toluene, and of isopropyl alcohol.
>>
>> Try not to smoke, and don't do this in the kitchen or basement with the
>furnace or gas-fired water heater running.
>>
>> The mixture of the above chemicals with MEK as the base and
>> Toluol 20%, Acetone 20%, Toluol 10% and alcohol 5% will make a
>particularly aggressive removing compound solvent for resinate
>> deposits including varnishes and polyurethanes.
>>
>> The mix will not heat up by itself unless you add water. Please avoid
>adding water. As long as you keep the mixture in a tightly sealed metal can
>in a very cool location like the basement floor it will keep for
>> months.
>>
>> Soak articles to be stripped in a covered enamel or stainless soak pan
>until the varnish, lacquer or poly has leached out into the solvent, and
>then use a parts brush with some clean solvent to finish up the tough spots.
>>
>> Paste type stripping compounds employ Methyl Chloride. Compared to the
>stuff listed above it's in a world of Haz-Mat all by itself. A definite
>order of magnitude nastier, by far, but it does work. If you end up using
>Strip-Eze, make sure you have a fan going nearby to blow the
>heavier-than-air cloud of vapors away from your work station and wear
>Nalgene or acid-resistant gloves. MC will burn your skin, but not right
>away. That's the nasty part.
