Procedure:
If necessary, use the 99% isopropyl alcohol soapy water and a clean microfiber towel to wipe away bugs / debris from the sensor.
Spray the sensor with warm, mildly-soapy water and gently wipe the sensor with a clean microfiber towel. Wipe along the curve of the sensor, not top-to-bottom (think moving with the grain).
Spray the sensor with clean water to rinse off the soap and dry with a second microfiber towel.
Enjoy your clean window!
