Sticky remotes and keyboards? Try this homemade 'slime'

Dust, crumbs, and debris easily accumulate between the keys on keyboards and remote controls. A homemade cleaning slime or a soft starch-based paste can help you remove dirt lodged in the hardest-to-reach crevices without taking your devices apart.

Remote controls, computer keyboards, video game controllers, and even certain surfaces in your car share a common problem: they accumulate dirt in the hardest-to-reach areas. Dust, hair, food residue, and small crumbs get stuck between the keys and in the crevices, turning everyday objects into true dirt traps. The result isn’t just a cosmetic issue. Over time, the buildup of debris can make the keys less responsive and promote the growth of bacteria.

Many people try to solve the problem using cotton swabs, toothpicks, or compressed air. However, there’s a simple method anyone can use to remove surface dirt without taking anything apart: homemade cleaning slime.

How does this soft paste that traps dirt work?

The principle is extremely simple. The slime has an elastic and slightly sticky consistency that allows it to conform to the shape of surfaces. When gently pressed against a keyboard or remote control, it seeps into the tiniest crevices between the keys and traps dust, lint, and crumbs.

Unlike a traditional cloth, which can only clean the outer surface, this soft paste reaches areas that are usually hard to clean. Once removed, it takes most of the accumulated dirt with it, leaving the object visibly cleaner.

The homemade starch-based version

Those who prefer to avoid specialized products can make a soft paste using ingredients easily found at home. A mixture of cornstarch and a little water creates a moldable, compact texture. It’s important that the paste isn’t too runny, to prevent it from leaving residue on electronic surfaces.

Knead the paste until it becomes elastic and smooth. At this point, simply apply it and press it gently onto the keys, without rubbing too hard. After a few seconds, remove it—it will come away with all the accumulated dust.

Be careful with moisture and residue

Although this method is practical, it requires a few precautions. Keyboards and remote controls must be turned off or unplugged before cleaning. Additionally, the slime or cleaning paste should not be too wet. A mixture that is too wet could leave streaks in the gaps or, in the worst case, cause unwanted moisture to seep in.

It’s recommended to check that the material used remains compact during use and doesn’t crumble between the keys. If you notice any residue, it’s best to stop cleaning immediately and remove it with a dry cloth.

A quick tip to extend the life of your devices

Regularly cleaning electronic surfaces does more than just improve the appearance of the devices we use every day. Periodically removing dust and debris can help maintain the responsiveness of the keys and reduce wear caused by dirt buildup.

Homemade slime is therefore a simple, economical, and quick solution for reaching even the most hidden nooks and crannies without having to take devices apart. It’s a handy household tip that, in just a few minutes, can make your keyboards and remote controls look much neater.
