8.6.3.5 Hand Cleaning Methods and Materials. Hand<br />
cleaning will be performed when components cannot tolerate<br />
other methods, when components are not easily removable<br />
from larger assemblies, or when other methods of cleaning are<br />
unavailable. Hand cleaning methods for electronics require the<br />
following materials:<br />
• Cloth, CCC-C-46<br />
• Cheesecloth, CCC-C-440<br />
• Cotton tip applicator<br />
• Acid Brush<br />
• Toothbrush<br />
• Brush<br />
• Lint-free cloth, A-A-59323<br />
