What clearing cache does and why you might need to

Clearing cache on your Roku removes temporary files the device has stored while you use apps — things like thumbnails from shows you've watched, login information, and pieces of web pages. Over time, these files can pile up and cause apps to load slowly, freeze, or crash. Clearing the cache is one of the first troubleshooting steps when a streaming app stops working properly.

You do not lose your saved passwords, watch history, or any settings when you clear cache. The Roku will straightforward forget the temporary shortcuts it created. The next time you open an app, it will rebuild those files fresh, which often fixes glitchy behavior.

Key Takeaways

  • Clearing cache removes temporary files stored by apps, not your passwords or account information.
  • The fastest method is to restart your Roku from the Settings menu, which clears cache automatically.
  • If a single app is misbehaving, you can clear just that app's cache without restarting the whole device.
  • After clearing cache, apps may take a few seconds longer to load the first time, then return to normal speed.

Restart your Roku to clear all cache at once

The simplest way to clear cache is to restart your device. On your Roku remote, press the Home button to go to the main menu. Scroll down and select Settings, then scroll down again and select System. You will see an option for Power — select that.

Choose Restart from the menu. Your Roku will shut down and turn back on, which takes about 30 seconds. During this restart, the device clears temporary files from all apps. Once it boots back up, your apps should run more smoothly.

This method works for all Roku models and is the fastest fix when multiple apps are acting slow or freezing. You do not need to unplug anything or wait for a specific amount of time.

Clear cache for a single app that is misbehaving

If only one app is having problems, you can clear just that app's cache without restarting the whole device. Press Home on your remote and navigate to the app that is giving you trouble. Highlight it but do not open it — instead, press the Options button (the button with three horizontal lines, usually on the left side of your remote).

A menu will pop up with several choices. Select Remove channel. This sounds drastic, but it only removes the app from your home screen and clears its cache — you are not deleting your account or any saved data within that app. Your login information and watch history stay intact.

After removing the channel, go back to the Roku home screen and search for the app again using the search function. Reinstall it. When you open it, it will load fresh without the corrupted temporary files that were causing the problem.

When to clear cache versus when to contact the app maker

Clearing cache fixes most app problems — slow loading, freezing, crashing, or videos that will not play. Try this step first before assuming the app itself is broken. If clearing cache does not solve the problem after two attempts, the issue is likely something else.

Check whether your Roku software is up to date, since outdated system software can cause app conflicts. Go to Settings, then System, then System Update to see if an update is available. If an app continues to fail even after clearing cache and updating your Roku, the problem may be with that specific app's version, and contacting the app maker's support team is your next step.

How to check if your Roku needs more storage space

Roku devices have limited storage, and a full drive can make apps slow even after clearing cache. Go to Settings, then System, then Storage to see how much space is available. If you are using more than 80 percent of your storage, you may need to remove apps you no longer use.

Highlight an app you do not watch anymore and press Options, then select Remove channel. This frees up space for the apps you use regularly. After removing a few unused apps, restart your device and see whether your remaining apps run faster.

Clearing cache on Roku TV models built into your television

If your television has Roku built in rather than using a separate Roku box, the process is identical. Use your TV remote to navigate to Home, then Settings, then System, then Power, then Restart. The TV will go dark for about 30 seconds and come back on with cache cleared.

For a single app on a Roku TV, highlight the app without opening it, press the Options button on your remote, and select Remove channel. Then search for and reinstall the app. The steps are the same whether you are using a Roku Streaming Stick, a Roku box, or a Roku-powered television.

Frequently Asked Questions

Will clearing cache delete my saved passwords and watch history?

No. Clearing cache removes only temporary files. Your passwords, account logins, watch history, and all saved preferences stay on your device. The next time you open an app, you will be logged in exactly as before.

How often should I clear cache on my Roku?

Most people do not need to clear cache regularly. Do it when an app starts acting slow or freezing. If you notice problems every few weeks, you may want to restart your Roku once a month as preventive maintenance, but it is not necessary for normal use.

Why is my app still slow after I cleared the cache?

Slow apps can have other causes — weak internet connection, outdated Roku software, or a problem with the app itself. Check that your WiFi signal is strong, update your Roku system software, and try restarting your internet router. If the app is still slow, the issue may be with that app's current version.

Can I clear cache without restarting my Roku?

Yes, by removing and reinstalling individual apps. However, restarting clears cache for all apps at once and is faster if multiple apps are misbehaving. Restarting takes about 30 seconds and does not interrupt anything — you can restart anytime without losing data.

Does clearing cache free up storage space on my Roku?

Yes, it does. Temporary files take up storage, so clearing cache gives you back some space. If your Roku is running very slowly and storage is nearly full, clearing cache plus removing unused apps will help the most.
