WD-40 Specialist Contact Cleaner Spray, 11 oz.

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!

Fraction of the cost of others! Works great!

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 well and made connections clean and running.

Great electronic cleaner for many uses. Doesn't hurt plastics, not alcohol, cleans well. I use it on a piece of denim to clean model RR tracks.

It has saved the shutter button of my camera, the joystick of my Switch Controller and many more. It's worth every single cent of the price.

⚡ WD-40 Contact Cleaner – Professional-grade efficiency at a budget price This was my first time trying this contact cleaner in my electronics lab, and I’m genuinely impressed. Despite its affordable price, it meets technical standards and delivers precise cleaning with no residue left behind. 🧪 I’ve used more expensive alternatives before, and this WD-40 Specialist performs just as well. 🎯 The built-in Smart Straw is a brilliant feature: it stays attached to the can and allows pinpoint application, perfect for delicate components. 💡 Overall, an excellent choice for professionals seeking reliable performance without overspending.

I grabbed this to clean some crusty old switches and a volume knob that crackled like a campfire. One quick spray and everything smoothed out like it was brand new. It evaporates fast, doesn’t leave residue, and didn’t melt anything important — always a plus. Perfect for radios, remotes, connectors, and anything that’s gotten a little “electrically grumpy” over the years. A must‑have for any toolbox.

एकदम बडिया है ये स्प्रे हर तरह के ईलेक्ट्राॅनिक चिज को साफ कर देता है यह और जो ईलेक्ट्राॅनिक चिज बंद पडी है उसे भी यह चालु कर देता है

I got some stick drift on my PS5 Dualsense controller. Did some res search and found this and BW-100 both could be used to clean the contacts. This product was significantly cheaper (I guess BW-100 isn’t really sold in Canada) so I tried it out.. sprayed it at the top of the stick, and took off the black cover around the thumbsticks and sprayed it into the holes on the side. Then I moved the sticks all around and clicked them in a few times. Once it was dry the stick drift has been “fixed” so far it has been about 3 weeks and it hasn’t returned, I know it’s not a permanent fix but definitely helped. Didn’t leave a residue from what I could tell and dried pretty quick.
