It’s not safe and not recommended to spray liquids directly on a keyboard, as they can seep into internal components and cause damage. Instead, use a lightly dampened microfiber cloth or cotton swab with water or isopropyl alcohol for cleaning. Always disconnect the keyboard or power off the device first, and avoid over-saturating cleaning tools to prevent liquid damage. Use compressed air for dust removal and clean under removable keycaps carefully if needed. If you want to know some useful methods to fix sticky keyboard keys then read the article.
