Great spray for cleaning electrical switches

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

Great product

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.

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

It’s WD-40, what do you expect! Does exactly what it made for, and does it very well - bought back to life a bank of micro switches that are no longer available. NO sticky residues, just be gentle on the button when spraying (I did put some paper towel behind the switches before hand, as there’s more equipment behind it) Overall, a very effective spray, that doesn’t require soaking the part, just to get it working. Quick and easy, how it’s meant to be!
