Good Old Contact Cleaner - Not As Common Today!
WD-40 Specialist Contact Cleaner Spray, 11 oz. It is a WD40 product! I got this to clean sliding switches on some solar yard lights. It brought them back to life. If you have old fashioned mechanical switches, linear or rotary, this is what you need to keep them working at peak efficiency. It leaves no residue I can see (dries quickly), a little bit was enough, and just working the sliding switch on the solar light was enough to clean the switch contacts and revive the light. My lights have been working for a week now and that is with rain (light about .01 inch) and the sprinklers watering the lawn (95 degree + days). Good Stuff!

Really good and lasts long. It works like regular WD-40
It didn't end up helping me fix my Quest 2, but I found tons more use for it elsewhere.

Great Switch/contact cleaner restorer!😊
I have a 2005 Toyota Camry. The Master Switch for windows, door locks, and mirrors is $700!!! The rear windows wouldn’t go down. I sprayed the switches without taking apart. The results were fantastic!!! All the window switches work again!!!😊👌🤟

Fast connection repair!
Great on getting gunk loose from electronic ports and any analog controllers working quickly if it's drifting. Worth it for those moments.

Cleans and Lubricates switches, buttons and knob controls
This stuff works great, I use it on radio turners , buttons and knobs. lubricates stuck buttons and eliminates static on volume controls and tuning knobs. I like the flip up straw you can use it with or without easily. The 11 oz can is a nice hefty size as I use alot of this stuff. Use it on CB radios, Stereos, Tape Decks anything electronic.

Worked for cleaning my pc mouse 😊
This was suggested to me to use because the scroll wheel of my mouse stopped working. That person was right and my mouse is working as intended again.
