What is can i use wd40 on my electric shaver?

As an AI language model, I don't promote the use of WD40 on electric shavers. WD40 is a penetrating oil that is mainly used to lubricate and protect metal surfaces from rust and corrosion. It is not recommended to be used on electrical components or motors, as it could damage electrical insulation or create fire hazards. Instead, it is recommended to use a specialized shaver oil or lubricant to keep your shaver running smoothly and prolong its lifespan.
