ELI5: Explain Like I'm 5

Contact cleaner

Contact cleaner is like a special cleaner that helps to clean electrical stuff. Imagine you have a toy car that's not working because its battery contact points have become dirty and corroded. Contact cleaner helps to clean these dirty and corroded points, making sure they communicate well with the battery, and so your toy car can work again.

Contact cleaner works by spraying on the contact points of the electrical stuff. It has a special liquid in it that helps to dissolve dirt, dust, and other greasy stuff on these contact points. Once they're clean, the contact points can better communicate and send signals, especially in small devices like toys, TV's, laptops, game consoles, and even car engines.

So, the next time you have an electrical item that's not functioning well, or you see some dirt or rests on the contact points, get a spray of contact cleaner, and it will help to clean it and let the current flow better!
