Some people have A/C stains on their asphalt shingles, it usually is becuase the drainage tube runs out onto the shingles leaving a White gooy look. I have had some success with toilet bowl cleaner....has anyone had any luck with another product?

does it clean up quickly? Do I rinse it with a hose afterwards? Thanks Zach.

I usually pre wet, Treat at 50-50 and then rinse very well. Maybe I've been lucky but I've had success every time I've used it.

OMG make sure you dont let F9 dry on the shingle. Use very weak solutions to start. Rinse it while its wet. I learned this lesson in the most painful way possible.
