This non-toxic, biodegradable cleaning slime from Cyber Clean is a great addition to the home or office. You can clean just about any surface like doorknobs, drawers, kitchen appliances, remote controls, keyboards, speakers, camera equipment and more. It's great for hard-to-reach crevices and can be used over and over. All you do is fold the dirt and grime into the slime and use until the slime turns a darker color that matches the swatch displayed on the container.
