Hydrophobic vs Self-Cleaning - They Are NOT the Same 
In the detailing industry, "hydrophobic" and "self-cleaning" are often confused, but they describe different surface behaviors.
Q: What is Hydrophobic?
A: A hydrophobic surface repels water, causing it to bead and roll off more easily. It reduces water adhesion and improves drying behavior.
Q: What is Self-Cleaning?
A: Self-cleaning refers to the surface's ability to reduce dirt and contamination buildup, often supported by water movement, surface slickness, and anti-fouling properties.
Key Difference:
Hydrophobic = Water repellency performance
Self-cleaning = Dirt removal & contamination resistance
