Acetone and mineral spirits are fine to use, the Acetone evaporates so fast it will not hurt anything (espicially good for evaporator). Cover seat, carpet, console with drop cloths, it will be messy fumes, use old towels and a baby
bottle to collect flush.

Charge low side with can upright for gas/vapor. My indy was seen turning can all around and I think that he sumped my compressor with liquid. also he did not purge gauge lines and may have introduced air. I got all kinds of weird readings, so read/study and DIY.
