Thanks for sharing, good info and video, some questions : how often do you clean it? Also don't you need to reinitialize the TPMS and the driver's side auto up/down window after disconnecting battery, also I believe all radio settings and users car function preferences like door locks are reset to factory defaults. There's a product you can buy that uses a 9V battery that you plug into cigarette outlet prior to disconnecting the battery so it keeps all settings.
also from experience, I don't recommend disconnecting the battery if one is planning to bring the car in for inspection soon, it resets the OBDII drive cycle to NOT READY and some emissions monitors are a real hassle to get ready and if not set, you will fail inspection, there's a certain driving pattern that must be followed for it to set.
