If you're a retro gaming enthusiast, chances are you've come across a dusty old NES cartridge or a PlayStation disc that's seen better days. Whether you're trying to play them, sell them, or just preserve your collection, knowing how to clean and restore old video games is a must.
In this guide, we'll walk you through safe, effective methods to clean and restore your old video game cartridges and discs — without damaging them. Let's get those classics working like new!
🕹️ Why Cleaning Retro Games Matters
Old games are physical media, which means they're vulnerable to dust, grime, oxidation, scratches, and more. Over time, this buildup can cause games not to load, skip, or completely stop working. Cleaning not only makes your games playable again, but can also increase their resale value if you're a collector or reseller.
🧽 Part 1: How to Clean Video Game Cartridges
Works for:
-
NES
-
SNES
-
Sega Genesis
-
N64
-
Game Boy (all variants)
-
Atari 2600 and more
🛠️ What You’ll Need:
-
Cotton swabs
-
Isopropyl alcohol (91% or higher recommended)
-
Soft-bristle toothbrush (optional)
-
Eraser (optional for deep corrosion)
-
Gamebit screwdriver (for disassembly)
âś… Step-by-Step Cartridge Cleaning:
-
Inspect the Cartridge: Check the pins and contacts for visible dirt or corrosion. Blow out any loose dust from the connector area.
-
Dip a Cotton Swab in Isopropyl Alcohol: Gently scrub the cartridge pins. You’ll likely see brown or black residue come off on the swab — that’s normal!
-
Repeat Until Clean: Use fresh swabs until they come away clean.
-
Dry the Contacts: Use a dry cotton swab to remove excess alcohol. Let the cartridge sit for a few minutes before testing.
-
Optional – Deep Clean with a Gamebit Tool: Open the cartridge case to clean the internal PCB. Be careful not to scratch the board.
-
Bonus Tip – Use a Soft Eraser: For tough corrosion, lightly rub the contacts with a clean eraser. Just be gentle!

Works for:
-
PlayStation 1, 2, 3
-
Xbox & Xbox 360
-
Sega Dreamcast
-
GameCube
-

🛠️ What You’ll Need:
-
Microfiber cloth

âś… Step-by-Step Disc Cleaning:
-
Rinse the Disc: Use warm (not hot) water to remove loose dirt.
-
Wash Gently with Soap and Water: Apply a drop of mild soap to a soft sponge and wash the disc in straight lines from center to edge.
-
Dry with a Microfiber Cloth: Always wipe from the center out — never in a circular motion.
-
Remove Scratches (Optional): Use a disc repair product like Novus or a buffing tool. Apply a small amount and polish in straight motions.
-
Test the Disc: After cleaning, test your game in a console. If it still skips, consider resurfacing it professionally.
⚠️ What NOT to Do
-
Don’t use acetone, Windex, or abrasive cleaners
-
Don’t wipe discs in circles — this can make scratches worse

Store games vertically in cool, dry environments.

Use dust covers for cartridges when possible.
-
