What is one way to remove excess penetrant when using solvent-removable penetrants?

Wiping with a rag dampened with solvent is the appropriate method for removing excess penetrant when using solvent-removable penetrants. This technique allows for controlled removal of the penetrant from the surface without damaging the part being inspected. The solvent helps dissolve the penetrant, and the rag effectively picks it up, ensuring that the surface is clean for accurate inspection.

The other methods are less suitable for this application. Using a sandblaster could damage the surface being inspected, as sandblasting is abrasive and could alter the part's integrity. Soaking the specimen in solvent, while effective at cleaning, may not allow for the precise control needed to avoid affecting the surrounding area or details on the part. A high-pressure spray has the potential to force penetrant into micro-cracks or other surface imperfections instead of effectively removing it. Therefore, wiping with a solvent-dampened rag is the safest and most effective approach for this purpose.
