How to Clear Cache on Any Device (Step-by-Step Guide)

Is your phone, computer, or browser running slow? Apps crashing? Websites taking forever to load?  It could be due to the amount of cached data blocking your system! Clearing cache clears space, boosts performance, and can fix common errors–but what do you do to accomplish this?

In this ultimate guide, I’ll walk you through how to clean cache from all devices–whether you’re using Android, iPhone, Windows PC, Mac, or web browsers such as Chrome, Safari, or Firefox. Let’s get started!

What is Cache & Why Should You Clear It?

Cache refers to temporary data that is stored in your mobile device to assist websites, apps, and programs load more quickly.

How Cache Works

• When you visit a site or download an app, your device will save files (images, and information) so it doesn’t have to restart everything each time.
• As time passes, this cache builds over time and could slow your device or cause problems.

Signs You Need to Clear Cache

✔️ Apps freezing or crashing
✔️ Websites not loading properly
✔️ “Out of storage” errors
✔️ Slow phone or computer performance

Clearing cache does NOT delete personal data (like photos, messages, or passwords)—only temporary files.
