Mass Flow Sensor Cleaner

I used this spray to clean the Mass Flow Sensor screen on my 2017 Nissan Rogue. I was getting a MIL message and after cleaning the screen with this spray, the message went away. Using this spray cleaner was "way" cheaper than buying and installing a new sensor.

What else can I say other than it worked well and did its job. I removed the mass air flow sensor from my vehicle, gave it a few bursts of this spray to clean the interior sensors and then reinstalled the mass air flow sensor back on the vehicle. The error code went away and I no longer have multiple alerts lighting up on my dashboard.
