I'd suggest you get a scangauge and actually document a problem with your A/F ratios before you start f'ing with sensor cleaning.

I think that's why they have you spray it 15 times, per the instructions on the can. It's just like the PB Blaster. You spray that thing on rusted nuts and bolts a few times and literally watch rust chip off on its own after a few minutes. If they're able to make a fluid that does that to rust, I'm sure they can come up with an equivalent to get grime of sensors.
