Can I use my old paper towels as a substitute for black fiberglass tissues in a pinch?

While it might be tempting to use old paper towels as a substitute for black fiberglass tissues, it is not recommended. Paper towels lack the strength and durability of fiberglass tissues, which are specifically designed for certain applications due to their heat resistance and insulation properties. Using paper towels could lead to ineffective insulation, potential fire hazards, or structural failure. It's best to use the appropriate materials as specified to ensure safety and effectiveness.
