Maguires No Touch Endurance Tire Spray

I was wondering how the formula works if anyone knows. I was guessing that it melts the tires to keep it looking black? I say this becuz when I rubbed it with a towel, a lot of black came off.

Thanx in advance

That's probably just dirt you're wiping off with the stuff.

Things aren't always as clean as they look

Yeah, it's called brake dust!
