Gumout 540041 Professional Formula Mass Air Flow Sensor Cleaner Spray, 11 oz – Safely Cleans Delicate MAF Sensors to Improve Engine Performance, Restore Power, Reduce Hesitation and Boost Fuel Economy

The Gumout Professional Formula MAF Sensor Cleaner is excellent for keeping your mass air flow sensor clean and performing well. It sprays evenly, evaporates quickly, and doesn’t leave any residue. Using it helps improve engine performance and fuel efficiency by removing dirt and grime buildup. The 11 oz can lasts through multiple cleanings, making it a good value. Overall, a must-have for anyone maintaining their vehicle’s air intake system.

I’ve tried a few spray adhesives before, but this one stands out. The spray comes out in a clean, even mist—no clogs, no mess—which makes it super easy to apply precisely where you need it. I used it on a foam board and a piece of lightweight fabric, and both bonded quickly and held strong. It dries clear, doesn’t warp the surface, and there’s barely any chemical smell. Compared to other brands I’ve used, this gives better control and a more professional finish. For the quality and performance, it’s a great value and a permanent fixture in my DIY kit. Also was pretty safe got on my hands and washed right off.

Works as needed and helped resolve a check engine light and rough idle. Just remove the MAF and spray it on and wait for it to dry and re-install.

Good value

Does a great job and lasts a long time.
