Frequently Asked Questions

Q: What does the Car AC Fluorescent Leak Detection Dye Agent do?

A: This fluorescent dye agent is introduced into your car's air conditioning system and circulates with the refrigerant. When you scan the system with a UV light, any leak points will glow brightly, allowing you to identify the exact source of a refrigerant leak quickly and accurately — without needing multiple applications or professional diagnostic equipment.

Q: Is the fluorescent dye safe for my car's AC components?

A: Yes. The formula is specially designed for automotive AC systems and is safe to use with rubber gaskets, O-rings, seals, and metal parts. It will not degrade or damage your system's components during normal use.

Q: Do I need a UV light to use this product?

A: Yes, a UV (ultraviolet) or black light torch is required to detect the fluorescent glow that indicates a leak location. The dye itself is not visible to the naked eye under normal lighting — the UV light activates the fluorescence for clear, easy identification.
