WD40 is NOT silicon spray.
Thing is, the propellent in some of these sprays is actually caustic to some plastics, turning them slightly brittle or at least tarnishing the smoothness of it. I'm surprised they say people use this on strings/racquets. Besides, if they absolutely wanted to be sure, all they'd have to do is feel the inside of the racquet plastic bag the pros take off. If it's slippery and leaves a slight film on your hands, they've been sprayed. This is honestly the first time I've head of this even happening.
