To clean sticking keys on a laptop keyboard, using compressed air is the most effective and safest method. Compressed air can dislodge and remove crumbs, dust, and other debris from under the keys without risking damage to the keyboard's electronic components or the keys themselves. This approach is non-invasive and widely recommended for keyboard maintenance.
