As foldable devices like the Samsung Galaxy Fold and Galaxy Z Flip grow in popularity, they bring together cutting-edge features with a sleek design that feels like the future of mobile technology.
Their unique build and delicate materials, from ultra-thin glass to flexible hinges, need the right kind of cleaning to stay in top shape. In this guide, you’ll see how to clean foldable screens like the Galaxy Fold and Z Flip screen, and care for other foldable such as Huawei and Oppo. All of the steps use safe, alcohol-free methods that keep your device looking sharp, well preserved, and working smoothly.
Exploring the Mechanics of Foldable Screens
Foldable phones like the Samsung Galaxy Fold and Galaxy Z Flip use Samsung’s Dynamic AMOLED displays — a type of OLED technology that delivers vivid colors, deep blacks and high contrast. What makes these screens special is their ability to bend without damage. This flexibility comes from ultra-thin, light-emitting layers built onto a flexible substrate. Instead of the rigid glass used in regular smartphones, foldable displays use a durable plastic polymer that can handle thousands of folds, keeping them functional and visually stunning over time
Varieties of Foldable Displays
Foldable devices generally fall into two familiar designs:
-
Clamshell (Flip) Style – Devices like the Samsung Galaxy Z Flip or Motorola Razr fold vertically, reminiscent of early 2000s flip phones.
-
Book-Style (Tablet-Fold) – Examples include the Galaxy Z Fold and Pixel Fold. These open like a book, expanding from phone-size to a larger, tablet-like display.
Materials and Construction
Foldable displays are marvels of layered engineering—all designed to be bendable, durable, and high-performing:
-
Flexible Substrate: At the foundation sits polyimide (PI)—a hardy, heat-resistant plastic that provides the bendable backbone for OLED layers.
-
OLED Display Layers: Above that, the TFT backplane controls each pixel while the OLED layers emit light. This thin-film stack lets foldables deliver vibrant colors in a sleek form.
-
Protective Cover: On top, there's a protective seal made of either flexible polyimide or ultra-thin glass (UTG)—the latter being both tougher and still flexible.
-
The Back Plane is typically made of thin, flexible materials that can handle the physical stress of bending.
Understanding how each layer plays a role—substrate, display, and cover—makes it clear why foldables are both innovative and delicate. These screens let you go from pocket-sized to tablet-width, but they also need care that respects their unique construction.
Step-by-Step Cleaning Process
Cleaning a foldable phone the right way is essential for keeping its screen clear and fully functional. Whether you’re learning how to clean a Galaxy Fold screen, a Galaxy Z Flip, or another foldable, the goal is to remove dust and smudges without scratching or damaging the delicate layers. Here’s the process we recommend.
Gather Your Cleaning Supplies
Firstly, what you want to do is assemble the right tools:
-
Soft Microfiber Cloth – For gently wiping the display without scratching it.
-
Rubber Air Blower – Ideal for removing dust from the hinge area without touching delicate parts.
-
Gentle, Alcohol-Free Cleaning Solution – Avoid harsh chemicals like acetone or bleach. Use cleaners specifically made for electronics.
Anti-Static Cleaning Wipes (Optional) – These help reduce static build-up, which can attract more dust to the screen.
Cleaning Steps
- Power Down: Turn off the device and unplug it from any power sources to see smudges more clearly and also to ensure safety.
- Initial Dry Wipe: Before applying any liquid, gently wipe the screen with a dry soft non-abrasive cloth to remove surface dust and debris.
- Apply Cleaning Solution: Moisten a microfiber cloth with a screen cleaner then gently wipe the screen in a circular motion, start from the center then move outwards, and avoid heavy pressure, especially near the fold line.
- Hinge Cleaning: Gently brush away debris from around the hinge using a fine soft brush. Optionally you could use a rubber air blower to remove any lingering particles without making contact.
- Drying: After cleaning, use a fresh microfiber cloth to pat down the screen softly and make sure it's completely dry. Avoid turning the device back on until you’re certain there's no moisture on or around the screen.

Additional Tips for Maintaining Foldable Screens
Optimal Folding Practices
Treat your foldable device gently, especially when opening or closing it. Avoid snapping it shut or flipping it open too quickly — even though devices like the Galaxy Fold and Galaxy Z Flip are tested for durability, repeated aggressive handling can still cause wear over time.
Before folding, check that there’s nothing caught between the screens, such as dust or small debris, as this can leave scratches or marks. While these devices can handle thousands of folds, reducing unnecessary folds each day can help extend the life of the hinge and display.
Handling Crease
The crease where your device folds is one of the most delicate areas of the screen. When cleaning it, use light pressure and a soft microfiber cloth to avoid long-term wear. Gentle, consistent care will keep the crease looking smooth and help maintain the screen’s flexibility for years to come.
