1. A method for testing a component with a penetrant test, comprising the steps of:
i) introducing a penetrant onto a surface of the component;
ii removing at least one portion of the penetrant from the surface by blasting the surface with a solid blasting material; and
iii) optically detecting the surface after the blasting:
wherein the surface is intermediately cleaned prior to the blasting and the surface is optically detected after the intermediate cleaning and before the blasting.
