WD-40 SpecialistContact Cleaner Spray - Precision Electronic Cleaning Solution for Switches, Relays & Connectors

The media could not be loaded. Totally impressed by this product as.it it really good at cleaning delicate connections and contacts such as potentiometers (knobs), switches and phono/headphone sockets with ease and without damage. It is quick use simply spray a very small quantity on the contact area to clean - moving the switch will also help. Wait a few seconds and the dirt and residue will be lifted away as the product evaporates completely. I have purchased before because it is such a good product, economical in use and doesn't damage the electrical components.

It works very well as is non conductive and a great degreaser, it works well as a fast drying "lubricant" to quickly position materials/items that need to be degreased and clean for their final seating positions.I use it all the time at work for cleaning circuit boards, flushing out hose pipes for flue gas analyser cells gas manifolds, cleaning flux from usb ports, and for automotive use it's fantastic at cleaning out electrical connectors.It isn't as strong as a defattening agent as pure isopropyl alcohol but as a pressurised aerosol the pressure helps displace some large deposits and like pure isopropyl alcohol it evaporates quickly in open air.Good stuff but rather expensive

someone suggested I try this before sending my PS5 controller off to Sony for repair. I was amazed at how quick this worked, don't need to open the controller, just spray a little in the gaps of the analog and rotate the joystick a bit to settle it in. The analog drift disappeared instantly!Absolute time and money saver! This is my miracle spray from now on

Excellent contact spray for those electrical contacts/switches. I use mine for cleaning electrical contacts in hi-fi equipment; relays, slider controls, potentiometers etc. it cleans the contact areas very well and with the adaptable sprayer (conventional or with thin tube) is very easy to use and control. It leaves no residue so keeps the treated areas nice and clean. You don’t have to use much so I see this lasting quite a long time 🤞

A few light, carefully aimed sprays of this into my Rift S VR controller’s analog stick instantly fixed my terrible stick drift. The key is to be cautious. Avoid letting it drip into the button areas, as it could damage the delicate rubberised membranes and make buttons unusable.For my purpose, this product worked wonders. It cleared out debris from the analog stick, leaving it feeling smooth and responsive. Two months later, the results have held up perfectly. For heavy VR users, this is a must-have for simple and effective controller maintenance.

Picked this up for a second-hand AV receiver and speakers I bought, and it worked perfectly. I could instantly see the difference on the contacts and even hear the improvement once everything was cleaned. There’s loads in the can so it goes a long way, and it left no smell, no residue, and no damage at all to the contacts. Really effective, good value, and I’ve still got plenty left for future use.

Used this on my PC ports and some old switches, and it cleaned them like new. Dries fast and no sticky left overs. A must-have if you work with electronics.
