What should be done immediately after contamination has been removed from a part?

• A. Leave it to dry
• B. Apply SP-207
• C. Do a final wash on the whole part
• D. Sand the surface

Answer: (C)

After contamination has been removed from a part, performing a final wash on the whole part is critical for several reasons. This step ensures that any remaining residues from the contamination removal process are eliminated, which can include cleaning agents or particles that may still be present. A final wash promotes thorough cleanliness, which is essential for subsequent processes, such as applying coatings or adhesives. It creates a clean substrate that enhances adhesion and performance of the next steps in manufacturing or assembly. Other methods, such as leaving the part to dry or applying a specific product like SP-207 immediately after contamination removal, do not address the potential residual contaminants that could compromise the quality of any further treatments. Sanding the surface may also not be appropriate at this stage, as it could introduce new contamination or alter the surface finish before ensuring the part is completely clean.
