What clearing cache does and why you might need to

Clearing cache means deleting temporary files that Roku stores while you use apps and stream video. Over time, these files can pile up and cause apps to load slowly, freeze, or crash. Clearing the cache won't delete your passwords, account information, or any shows you've saved — it only removes the temporary junk that builds up in the background.

Most people clear cache when an app stops working properly or when their Roku feels sluggish. It's one of the first troubleshooting steps that actually works, and it takes less than two minutes.

Key Takeaways

  • You clear cache through the Roku settings menu under Storage, not through individual apps.
  • Clearing cache removes temporary files only and does not delete your passwords, account logins, or saved content.
  • The process is the same on all Roku devices — remote control, no computer needed.
  • If an app still misbehaves after clearing cache, uninstalling and reinstalling the app is the next step to try.

How to clear cache on any Roku device

The steps are identical whether you have a Roku TV, a Roku streaming stick, or a Roku box. You'll use your Roku remote and navigate through the settings menu.

Step 1: Open Settings. From your Roku home screen, scroll up to the top menu and select Settings (the gear icon). Press OK on your remote.

Step 2: Go to Storage. Scroll down and select Storage. This is where Roku keeps information about what's stored on your device.

Step 3: Select Clear Cache. You'll see an option that says Clear Cache. Highlight it and press OK. Your Roku will show a confirmation message. Select Yes to confirm, and the cache will clear in a few seconds.

That's it. Your Roku will return to the settings screen when it's done. You don't need to restart your device — it happens automatically.

When to clear cache versus when to restart your Roku

Clearing cache and restarting are two different fixes for two different problems. If an app is frozen or won't load, try clearing cache first. If your whole Roku is running slowly or apps are crashing across the board, a restart often works better.

To restart your Roku, go to Settings, then System, then Power, and select System Restart. Your Roku will turn off and back on, which clears temporary memory and often fixes widespread slowness. You can also unplug your Roku for 30 seconds and plug it back in — that's a hard restart and works just as well.

If clearing cache doesn't fix a single app that's misbehaving, uninstall the app, restart your Roku, and then reinstall it from the Roku Channel Store. This removes all the app's files and gives it a fresh start.

What happens to your accounts and saved content

Clearing cache does not touch your login information. You won't be logged out of Netflix, Hulu, YouTube, or any other service. Your saved shows, watchlists, and preferences stay exactly where they are.

The only thing that disappears is temporary data — things like thumbnails that load faster the second time you watch, partially downloaded video segments, and app data that's no longer needed. Think of it as emptying a trash can that your Roku fills automatically.

If clearing cache doesn't fix the problem

If an app still crashes or freezes after you clear cache, the next step is to uninstall and reinstall it. Go to Settings, then Apps, then Manage Installed Apps. Find the app that's giving you trouble, select it, and choose Uninstall. Wait a few seconds, then go to the Roku Channel Store, search for the app by name, and select Install.

If multiple apps are misbehaving or your Roku is still slow after clearing cache and restarting, a factory reset may be necessary. This erases everything and returns your Roku to the state it was in when you first got it. You'll need to sign back into your accounts and reinstall your apps, but it fixes deep software problems that cache clearing can't touch. Go to Settings, then System, then Factory Reset to start this process.

How often should you clear cache

You don't need to clear cache on a schedule. Only do it when you notice a problem — an app acting up, loading slowly, or crashing. If your Roku runs smoothly, there's no reason to clear cache regularly.

That said, if you use your Roku heavily every day and notice it getting slower over weeks or months, clearing cache once a month can help keep things running smoothly. It's harmless and takes two minutes, so there's no downside to doing it occasionally even if you don't have a specific problem.

Frequently Asked Questions

Will clearing cache log me out of my apps?

No. Clearing cache removes temporary files only. Your login information, passwords, and account details stay saved. You'll stay logged into Netflix, Hulu, YouTube, and every other service you use.

Can I clear cache on individual apps instead of the whole device?

The Roku settings menu clears cache for all apps at once — there's no option to clear cache for just one app. If one app is the problem, uninstalling and reinstalling it is more effective than clearing cache alone.

What's the difference between clearing cache and a factory reset?

Clearing cache removes only temporary files and takes seconds. A factory reset erases everything — all your apps, logins, and settings — and returns your Roku to brand new condition. Only do a factory reset if clearing cache and restarting don't fix the problem.

Does clearing cache free up storage space on my Roku?

Yes, but usually not much. Cache files are temporary and relatively small. If your Roku is running out of storage, uninstalling apps you don't use will free up much more space than clearing cache.

Why is my Roku still slow after clearing cache?

Slowness can come from weak WiFi, too many apps running at once, or an outdated Roku software version. Try restarting your Roku and your WiFi router, then check for software updates in Settings under System. If that doesn't help, a factory reset may be necessary.
