Contamination on the fixture prevents ferrules from protruding equal distance from the base of the fixture.

This mainly applies to fixtures for polishing ferrule only (as opposed to connector polishing).  The ferrules must protrude the same amount from the bottom of the fiber optic polishing fixture, to ensure consistent pressure being applied to all ferrules.

Contamination at the top of the bore, where the ferrule flange sits on, will cause the ferrules to sit higher and protrude less.   If ferrules are protruding different length from the bottom of the fixture, this results in unequal pressures being applied to the ferrules during polishing, again resulting in variation in Radius values, FH values, and fiber end-face polish quality (scratches).
