2he part is first thorou"hly cleaned of oil, dirt, etc, then a liquid penetrant is applied to the surface to be e#amined and allowed to enter the discontinuties. All e#cess penetrant is then remo!ed, the part is dried, and a de!eloper is applied. 2he de!eloper functions both as a blotter to absorb penetrant that has been trapped in discontinuties and as a contrastin" bac*"round to entance the !isibility of penetrant indications. 2he dyes in penetrants are either color contrast $!isible under white li"ht% or fluorescent $!isible under ultra!iolet li"ht%
