WD-40 Specialist Contact Cleaner Electrical Spray, 400ml with Smart Straw, Fast Drying and Residue-Free, Contact Cleaner for Circuit Boards, Switches, Sensors, and Gaming Equipment, 1-Pack

I recently used this contact cleaner on my switches, relays and small circuit boards, and it worked brilliantly. It sprays easily with precision thanks to the Smart Straw, cleans away oil, dirt and condensation very quickly and, importantly, leaves no residue. According to the manufacturer it removes over 95% of common surface contaminants and is safe on plastic, rubber and metal. It’s become a go-to product in my toolkit when servicing electronics and electrical panels — I can rely on it to deliver a clean, dry finish which helps improve contact performance. Highly recommended if you want a quality solution for maintaining switches and connectors.

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

Appears to work as advertised. Happy with the product. Application tube useful for applying in tight corners.

Great product helped fixed my gaming controllers highly recommend
