Preparing to Clean the Computer

Before cleaning a used computer, there are a few things you should do to ensure that the process goes smoothly.

Backup Your Data

The first thing you should do is back up your data. If the computer has any important files or documents, make sure to save them to an external hard drive, cloud storage, or a USB flash drive. This will prevent you from losing your data if anything goes wrong during the cleaning process.

Gather Your Cleaning Supplies

Next, you will need to gather your cleaning supplies. You will need a soft cloth, compressed air, a small brush, and some rubbing alcohol. It’s important to use a soft cloth to avoid scratching the computer’s surface. Compressed air and a small brush will help you clean the hard-to-reach areas of the computer. Rubbing alcohol is also useful for disinfecting the keyboard and mouse.

Clean the Interior
