WD-40 Specialist Contact Cleaner 400ml (92716)

You must be 18 years old or over to buy this product.

Quick-drying, non-conductive spray. Easily cleans oil, dirt, flux residue and condensation from sensitive electronics and electrical equipment. Improves electrical contact in cars in damp conditions. Simply spray on and allow the product to dry before powering up. Rapidly penetrates into hard to reach areas to remove all the contaminants that cause current leakage and component failure. Ideal for use on circuit boards, switches, spark plugs and tape heads. Safe to use for cleaning plastics, rubber and metal. Because it contains PTFE, it sticks to the surface, repels water and withstands temperatures of -20°C to 100°C. Keeps tools and machinery working smoothly. Improves the life of garden tools and car parts. Protects against rust and corrosion. Sprays on easily with a protective coating for auto hinges, gears, sprockets, winches and chains, latches, door tracks, pulleys, cables, tow bars and guide rails. Flip straw down for spray or up for a precise, narrow spray. 360° valve allows for upright or upside-down application.

Will the product attack lettering on circuit boards?

Some circuit boards I have to clean have writing on them to indicatw which components fit in a certain place. Would this remove them? (I want them to stay!) It would be fine if it contains IPA
Asked by: petertheplumber
Please confirm what type of ink was used. Was it permanent marker, wet erase marker, factory printed onto the PCB? We don’t generally hand out formula information, though this is a cleaner and we publish the ingredients on our website of all cleaners. The ingredients list can be viewed at https://wd40.co.uk/data-sheets/#wd-40-specialist . We recommend that you test the product on a small area first to assess compatibility with the writing. Some useful hints. Avoid spraying the devices contacts directly while in the product housing as the spray could force it’s way into the case and cause damage in an enclosed space. (Usually the circuit boards are taken out of devices, cleaned and allowed to dry in the open before replacing in the housing) Never spray near a screen (Liquid crystal, touch screen, etc) These are sensitive electronic components which can be damaged easily. Never clean up any battery terminals if leakage occurs – rather dispose of in an appropriate manner (please contact your manufacturer for disposal guidelines)

What's the main ingredient in this cleaner?

I'm looking for the highest concentration of isopropyl alcohol in a spray can. Would you know if this contains isopropyl alcohol? If so, what percentage? Thanks
