ABSTRACT:
A pre-wash stripper composition for use in the water-washable inspection penetrant process consisting of water saturated with dissolved penetrant. The saturated solution cannot dissolve more penetrant, and is therefore incapable of causing depletion of crack entrapments, but when applied to test surfaces by spray, it is capable of removing surface penetrant from test parts to completion of the so-called incubation of washing, and for purposes of recovery of excess surface penetrant for re-use. Test parts which have been pre-washed with the inhibited saturated solution may be finish-washed in clean water with a minimum amount of penetrant carry-over into the finish-wash water.
