Brad, I take it that is a water/alcohol based solvent then? How bad is it on wood finish or Tupperware stocks.
I have come to prefer solvents that are not aggressive and may need to work over night. Rather than having to run a bunch of patches through and still not be clean.
Had a bad experience with Barnes copper cleaner years ago. Won a bottle of it at a match. Used it in a rifle and did not get it all out of the front of the action, you guessed it. Put it in the safe and it froze the bolt up in the action, had to beat it open. The to top that had mysterious rust on some other guns, I suspect the gas from the ammonia.
No more for me, thank you.
