Did you frame this question on purpose for violence? Virtue signal answer: completely disassemble and use air, putty, alcohol and mini vacuum My real answer: turn it upside down and blow on it super hard so the crumbs hit you right in the face and if you're lucky you can score an afternoon snack as a reward
Spread peanut butter over the keys and pass it to the dog
Turn it upside down and tap a corner against the desk. For a deep clean tap the other corner too.
Definitely turn it sideways and smack it. If you're feeling froggy, use an alcohol swab to get in between some gaps. Then simply live with the fact that you know there are still random crumbs embedded under that space-bar.
I've found that a really good vacuum with bristles gets under the keys good, then some alcohol wipes for the oils and dust
Don't clean it - the buildup of hair, natural oils and foodstuffs adds a nice tactile response to your key strokes
Remove all of the caps, soak in warm soapy water. Wipe dry afterwards, set on paper towel to dry. Shake off crumbs outside with the keyboard without caps. Use mixture of isopropyl alcohol and water with q tips to clean in between the switches.
depends what kind of keyboard i have a feeling that you use a bad keyboard, so if that’s the case i suggest you throw it away
