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

While it might be tempting to repurpose old towels as a substitute for black fiberglass tissues, it's not advisable. Black fiberglass tissues are specifically designed for certain applications due to their unique properties, such as heat resistance and strength. Old towels, even if they are black, lack these specific characteristics and may not provide the same level of performance or safety. It's best to use materials as intended to ensure effectiveness and avoid potential issues.
