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! Review: 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!!!😊👌🤟 ## Features - WD-40 Specialist Contact Cleaner is ideal for removing oil, dirt, flux residue, and condensation from sensitive electrical equipment.

There is no lubricant component in the cleaner. **Q: Can this spray be used on plastic surface (ex: headphone) to "prevent" dirt, dust, or fingerprint?** A: This product, while safe on most, if not all, plastics is designed for cleaning electrical contacts and related items. It is not meant to be used as a wax or polish. Hope this helps. **Q: Would this clean a water damaged phone circuit board?** A: The problem with this product is its evaporation rate. All you'll be doing is replacing the water with the contact cleaner. The circuit board will remain saturated until it's either purged with compressed air or allowed to bake in the sun. CRC contact cleaner will purge and then evaporate quickly (while you watch). WD is cheaper but you get what you pay for. **Q: will this melt plastic or discolor it if accidentally spilled on it?** A: It might. If you're not sure, put a small amount of it on the plastic and see what happens first. If nothing happens then spray away... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Old Contact Cleaner - Not As Common Today! *by R***N on September 28, 2025* WD-40 Specialist Contact Cleaner Spray, 11 oz.
