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!

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!!!😊👌🤟

IT JUST WORKS
This stuff worked extremely well. I have a 40 year old Sony Discman that had a noisy volume potentiometer...a few sprays and working the volume wheel back and forth a few times eliminated the noise completely. This dries quickly and leaves zero residue. Very impressed with the effectiveness of this product.

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.

beats sandpaper or brushing any day
I use when I’m trying to find a oil leak on something, it cleans all that oil off and I can see it starts to drip, and I can track it back often to the source.. I’ve been tinkering for years, and WD-40 Specialist Contact Cleaner has become my go-to for keeping everything running smoothly. It evaporates fast without leaving residue, doesn’t harm plastics or metals, and the precision straw makes it easy to target those tiny spots. No more static or intermittent issues on switches, connectors, or circuit boards. Absolutely worth every penny—five stars all the way! If you’re dealing with dirty contacts or grimy electrical components, this is a lifesaver. Highly recom
