How to Clear Cache and Storage on Firestick: Speed It Up (2026)
Step-by-step guide to clearing cache and freeing storage on your Fire TV Stick in 2026. Covers the new one-tap all-apps method, per-app clearing, and what NOT to accidentally delete.
My Firestick 4K Max had been crawling for weeks — apps taking forever to load, Netflix stuttering on the home screen, Kodi hanging mid-browse. I blamed my router. I blamed Amazon. Turns out the culprit was a few gigabytes of accumulated cache I’d never bothered to clear.
Fifteen minutes of cleanup later, the device felt like new. No factory reset, no reinstalling anything, no paid app required. Just a few taps in Settings.
This guide walks through exactly what I did — including the newer one-tap “clear everything” option that Amazon quietly added to Fire TV, plus the app-by-app method for when you need to target a specific problem.
To clear cache on Firestick in 2026: go to Settings → Applications → Clear All Application Caches for a one-tap cleanup of every installed app. If that option doesn’t appear (older Fire TV software), use Manage Installed Applications → select an app → Clear Cache to do it one app at a time. Neither method deletes your logins or app settings — that’s Clear Data, which is a separate and more drastic action.
What I Tested For
I ran this on a Firestick 4K Max (Fire OS 8) with about 40 apps installed — a mix of streaming services, sideloaded APKs, and the usual Amazon bloatware. I checked:
- How much storage the cache cleanup actually reclaimed
- Whether logins and app settings survived the cleanup
- Which method worked fastest for general maintenance vs. targeting a single broken app
- What the “Clear Data” option actually does (and when it’s the right call)
- Whether the newer “Clear All Application Caches” shortcut is available across devices
One honest caveat upfront: I only tested US-region devices running recent Fire OS builds. If you’re on an older Firestick Lite or a very outdated software version, some menu paths may look slightly different.
Method 1: Clear All Application Caches at Once (Recommended)
A recent Fire TV software update added a single button that wipes temporary files across every installed app in one shot. This is the fastest way to do a general cleanup.
Clear All App Caches on Firestick
4 stepsOpen Settings
From the Firestick home screen, press the Home button on your remote, then navigate to the top of the screen and select Settings (the gear icon on the far right).
Go to Applications
Scroll right and select Applications. On the right side of this screen you’ll also see your current internal storage usage — useful to check before and after.
Select Clear All Application Caches
Look for Clear All Application Caches near the top of the Applications menu. Select it, then confirm when prompted. Fire TV will clear temporary files for every installed app at once.
Restart Your Firestick
After clearing cache, do a quick restart: Settings → My Fire TV → Restart. This helps the device finish the cleanup and refreshes system processes. You’ll notice the difference when it boots back up.
Method 2: Clear Cache for a Single App
This is the right approach when one specific app is acting up — crashing, buffering, or refusing to load. It’s more surgical than the all-at-once method and lets you confirm the fix worked before touching everything else.
Clear Cache for One App on Firestick
4 stepsOpen Settings → Applications
Navigate to Settings → Applications → Manage Installed Applications.
Find the Problem App
Scroll through the list and select the app giving you trouble. Common candidates: 
Kodi, 
Netflix, 
Stremio, or any IPTV player.
Select Clear Cache
Inside the app’s settings, select Clear Cache. You’ll see how many MB of cached data it’s holding — sometimes it’s surprisingly large for apps you use daily.
Relaunch the App
Close out of Settings and reopen the app. If the issue was cache-related, it should load cleanly. First launch after a cache clear can be slightly slower than usual — that’s normal.
Comparison: All the Ways to Free Up Space
Cache clearing is the quick fix, but it’s not the only tool available. Here’s how the main options stack up:
| Method | Storage Freed | Removes Logins? | Permanent? | Best For |
|---|---|---|---|---|
| 🏆 Clear All App Caches | Moderate | No | No — rebuilds with use | Routine maintenance |
| Clear Cache (per app) | Small–Moderate | No | No — rebuilds with use | Single app troubleshooting |
| Uninstall Unused Apps | Most | Yes (app gone) | Yes | Freeing significant storage |
| Clear Data | Moderate | Yes | Yes (until you use it) | Stubborn app crashes |
| Restart Only | Minimal | No | No | Quick performance refresh |
The honest truth: cache clearing is the easiest first step, but uninstalling apps you never open is usually what actually moves the needle on storage. Cache comes back. Removing apps doesn’t.
How to Check Your Available Storage
Before and after any cleanup, it’s worth knowing where you stand.
Go to Settings → Applications — on the right side of the screen you’ll see your total internal storage and how much is currently free. On a standard Firestick 4K Max with 8GB internal storage, anything below 1GB free is worth addressing before it starts affecting performance.
When Clearing Cache Isn’t Enough: Uninstalling Apps
If you’ve cleared cache and your Firestick is still sluggish or showing “low storage” warnings, the next step is uninstalling apps you don’t actually use. This is the cleanup step that frees the most space.
In Settings → Applications → Manage Installed Applications, you can see the storage footprint of every installed app. Some sideloaded apps accumulate surprisingly large caches over time — I found a Kodi build that had ballooned to over 400MB. Removing an app removes its data completely, so you’ll need to reinstall and set it up again if you change your mind.
The most effective cleanup combo: clear all caches first, restart the device, then uninstall anything you haven’t opened in the last 30 days. That two-step approach is what turned my sluggish device around.

→Troubleshooting: Cache Cleared but Still Slow?
Cache clearing helps with temporary storage bloat and app glitches — but it’s not a magic fix for every performance issue. Here are the common next steps if your Firestick is still slugging along after a full cache wipe:
App still crashing after clearing cache? Try Clear Data for that specific app. It’s the more aggressive reset — it’ll sign you out and wipe app settings, but it also clears anything the cache clear missed. Go to Manage Installed Applications → select the app → Clear Data.
Whole device still slow? Check how many apps are running in the background. The Firestick doesn’t manage background processes the way a phone does — too many apps left open can drag down performance. Restart the device regularly, ideally after every cleanup session.
Storage still low after clearing cache? Cache rebuilds quickly as soon as you start using apps again. The durable fix is uninstalling apps you don’t use. See the 15 tips for speeding up your Firestick for a full performance checklist.
Device running warm and sluggish consistently? This might not be a storage problem at all — check our Firestick troubleshooting guide for hardware and connectivity fixes.
The Full Storage Cleanup Checklist
If you want to give your Firestick a proper deep clean rather than just a quick cache wipe, here’s the order I use:
- Settings → Applications → Clear All Application Caches — one tap, done
- Restart the device — Settings → My Fire TV → Restart
- Manage Installed Applications — sort by size, uninstall anything unused
- Re-check storage — Settings → Applications, right side of screen
- If an app is still misbehaving — Clear Cache for that app specifically, then Clear Data only if that doesn’t fix it
That sequence covers everything short of a factory reset. Speaking of which — don’t factory reset just because your device feels slow. That’s the nuclear option and it deletes everything. Cache clearing plus app uninstalls handles 90% of performance issues without touching your setup.
For more on optimizing your device beyond cache management, the Firestick performance optimization guide goes deeper into settings tweaks worth making.
Wrap Up
Clearing cache on your Firestick takes about two minutes and it’s free — Amazon built the tools right into Settings. Use Clear All Application Caches for monthly maintenance, the per-app method when troubleshooting a specific app, and reserve Clear Data for when cache clearing alone doesn’t cut it.
The cache will come back. That’s normal — it’s how apps work. The goal isn’t a permanently empty cache, it’s keeping it from building up enough to slow things down.
If you’re also sideloading apps and want to keep that side of your setup protected, Surfshark is what I run on my Firestick — native app from the Amazon Appstore, quick to set up, and it handles privacy without getting in the way of streaming.
