      Yes, the MG 4140 does as well.

      Yeah. I don't recall it ever having damaged anything, but I'm pretty
      consistent about getting it where it's needed and nowhere else.
      Sometimes you can't help overspray, though. Connector shells, sockets,
      beepers with plastic enclosures, etc...never had any issues.

      Interestingly, I was in a PCB assembly house yesterday, letting them
      schmooze me a bit because I'm shopping around a big board assembly job.
      They do full-board spray defluxing there, using MG #4140...but from
      MUCH MUCH larger containers. ;)

      That's scary. I use their contact cleaner quite a lot as well, but I
      try to avoid letting it touch anything but the contacts, just on general
