Question 5 • Computer Science Foundations

How should you clean the keyboard on your desktop computer? Check all of the boxes that apply.

Answer
A
Hold your keyboard upside down over a wastebasket.
B
Gently shake the keyboard.
C
Hold the keyboard vertically over a wastebasket and spray with compressed air.
D
Remove each key from the keyboard, and use a cotton swab to get dust, oil, and dirt out.

Explanation

Turn the keyboard upside down over a wastebasket so loose debris can fall out, and gently shake it to help dislodge crumbs and dust. You can also hold it vertically over the wastebasket and use compressed air to clear debris between the keys. Removing every key to clean underneath with cotton swabs is not a routine cleaning step and can damage the keys or keyboard.
