A useful applicant for home, garden, and automotive purposes, even the occasional tech hobbyist can find various uses for a can of Water Displacement, 40th Formula . But DIY computer-builders and vintage radio restorers be warned: the traditional WD-40 Multi-Use Product is not designed to be used on electronics. What's the big deal, you may be asking?

You'll want to steer clear of anything 70% or lower, which is loaded with water, lingers on surfaces, and takes forever to evaporate. Not exactly what you want anywhere near sensitive electronics.There are several other brands that produce safe and reliable contact cleaners for electronic equipment, many of which you'll be able to find right on Amazon. Thisis one of the site's top-rated contact cleaners , and it's designed to leave behind zero residue and is engineered to protect against contact failures.emphasize tools like cotton swabs, microfiber cloths, and isopropyl alcohol. All of which are just as effective at removing dirt and grime from a circuit board and other sensitive electronics., in which we recommend using a soft-bristled brush to dislodge dirt and dust clumps.
