WD-40 Specialist Contact Cleaner Spray, 11 oz.

I try to keep this contact cleaner on hand because it has pretty much unlimited uses. I bought one can. My ceiling fan was making an irritating grinding noise, I sprayed it, spun it around by hand and left it. The next day no noise. A button on my pinball machine wasn’t working. I sprayed it, worked it a bit and it was good as new. I used it to clean the gunk out of the electronic lock on my front gate before lubricating it. The monitor on one of my Bally Game Maker poker machines had trouble coming on. I sprayed the connector plugs and it works perfectly. I sprayed the bill acceptor in the same machine to clean out years of accumulated gunk. I use it on circuit boards, switches, computer fans and so much more. Yeah, pretty much unlimited uses. I ordered one can and found so many uses for it that it was nearly empty in a week so I ordered two more. It's an excellent electronics/electric cleaner and it drys quickly. However, I do strongly suggest making sure whatever you spray is dry before powering it up. It won’t take long.

I bought the WD-40 Specialist Contact Cleaner to fix stick drift on my son's PS5 controller, and it worked great so far.A couple of quick sprays into the joystick mechanism and it cleared up the issue.I really appreciated that it dries fast and doesn’t leave any residue behind.My son saw this on a tiktok video and we decided to try it out.Definitely a handy product to keep around for cleaning sensitive devices.

This WD-40 electrical contact cleaner is great! It's slightly cheaper than the competition. It smells like mostly alcohol. It flashed off fast. I love the built in straw because those little red straws are otherwise difficult to deal with. The attached straw doesn't have that problem. I would EASILY but this again.

As expected

Very good product. I used this on an old 80s car wiring harness connectors/plugs. Over all the year, all of the wires & plugs had become absolutely covered in dirt, oil, and some corrosion. I unplugged all of the connectors, and sprayed a copious amount of this cleaner all over the wires, contacts, and everything in between. I could see some seriously nasty stuff coming off in troves. After I was satisfied with the cleaning results, I used an air compressor to dry off and blow away any remaining dirt/residue. I am very satisfied with this product, and the only bad thing I can say is I didn't buy 2 cans.

When you have a classic car those electrical contacts get a little crusty. WD contact cleaner hits the mark. Super easy to use and a great value. Precision sprayer is a huge bonus over other brands.

I had a 400 watt power inverter that was making a loud racket! It was clogged with dust from the last 4 years of constant use. I took it apart and blew it out with this product and it worked awesomely!

Works well on guitar and amplifier potentiometers, cleaned up the dead spots and crackling on several pieces of vintage equipment
