Hi, thanks for your question. You can use the Contact Cleaner formula without issue on the range hood control panel...but for better grease control you might consider WD-40 Specialist Cleaner & Degreaser. Thank you for choosing WD-40 Brand Products.

                  I had some hydraulic fluid that he got sprayed inside of an electrical cabinet. It was all over the wires, HMI and PC boards. WD-40 specialist contact cleaner was safe to use on my PC boards inside of my machine, as well as taking off all of the hydraulic oil and helping me get everything clean inside my electrical cabinet. It’s a great product easy to use. The nozzle helps reaching those hard to reach corners where oil puddles up.

                  I saw this product on the shelf and said, “Hmm, let me buy it and try it and hope it doesn’t mess up anything I use it on.” To my surprise, this contact cleaner works great. I’ve used it to clean the debris inside my phone charging and headphone ports, sprayed it inside ignition coil packs when doing tuneups, and used it to clean up oil/grease on electrical connectors in the engine bay of my cars. It dries quickly and has not damaged anything I’ve used it on. Been using this product for over a year and a half. I plan to use it to clean the mass air flow sensor since it is safe for electronics. I have sprayed it inside ignition coil packs after spark plug replacements and have had no issues so far. Highly recommend it! And, Home Depot has the best price in town for this spray contact cleaner.

                  This spray rusted out my switch
                  I had high hopes for this product. But instead within 2 days of spraying, my switch was destroyed by the rust WD-40 caused. This is a special OEM spring activated Weed Eater switch so now I'm stuck with a useless Weed Eater. Do not buy this spray.

                    Used this on all the selectors and switches of a 1970’s Silver Marshall stereo receiver/amplifier. Cleared up all the “scratch” noise. Very pleased with the results.
