What cleaning tool is NOT recommended for CAL?

• A. Nylon utility brush
• B. Wire brushes
• C. Gun solvents
• D. Isopropyl alcohol

Answer: (C)

The choice of gun solvents as the correct answer highlights that these substances can have corrosive effects on certain materials used in the construction of Composite Active Layer (CAL) or similar equipment. Gun solvents are often designed to break down gunpowder residue and can be harsh on delicate components, potentially leading to degradation over time. Nylon utility brushes are generally safe and effective for cleaning as they provide gentle abrasion without damaging surfaces. Wire brushes can also be utilized in specific cases to remove more stubborn grime, though care must be taken to avoid scratching sensitive surfaces. Isopropyl alcohol is known for its good cleaning properties and evaporates quickly, making it suitable for cleaning electronic components and surfaces without leaving residue. Therefore, the inclusion of gun solvents as not recommended stems from their potential to harm materials rather than for lack of effectiveness in cleaning overall.
