Commercial refrigeration guys use an oil/soap solution that
comes in a conainer with a ball swab that is simply a leak detector that is coated on fittings after a
repair to double check for leaks at fittings that have been reassembled and it is green in color.
Possibly it was used . If so, nothing to worry about.
