How to Clean and Maintain Display Trays for Retro Handhelds

Quick answer

Clean your display tray every two to four weeks using a soft microfiber cloth and a can of compressed air. Remove all handhelds first, dust the tray’s surface and slots, then wipe with a barely damp cloth. This prevents dust buildup and scratches without risking the finish or the electronics.

Why display trays need a different cleaning routine

Display trays are not just shelves; they have molded slots, printed graphics, and sometimes a glossy finish that can be harmed by household cleaners. The trays that hold Micro Players like the Tetris Micro Player Pro or Street Fighter II Champion Edition are designed to show off the handheld’s screen and artwork, so any dust or smudge is immediately visible. Unlike a plain shelf, a display tray has crevices where dust settles and where a wet cloth can push moisture into the tray’s base. That’s why the process below uses dry methods first and keeps liquids to a minimum.

Gather the right tools before you start

You do not need a cabinet full of supplies. A microfiber cloth (at least two: one for dusting, one for wiping), a can of compressed air with a straw nozzle, a soft-bristle brush (like a clean makeup brush or a dedicated electronics brush), and a 50/50 mix of distilled water and isopropyl alcohol in a spray bottle. Avoid paper towels, which can leave lint and scratch glossy surfaces, and never use ammonia-based glass cleaners or abrasive pads.

Step-by-step cleaning for display trays

Follow these steps in order to avoid pushing dust into corners or scratching the tray. Each step includes a checkpoint so you know you are on track.

• Step 1: Remove all handhelds and accessories. Place them on a clean, soft towel. Checkpoint: never clean around a handheld; dust can fall into its buttons or screen.
• Step 2: Dry-dust the tray surface. Use a dry microfiber cloth to wipe the flat areas and the outer edges. Use the soft brush to sweep dust out of the molded slots and corners. Checkpoint: if you see dust flying, you are brushing too hard; let the brush do the work.
• Step 3: Blow out the slots and crevices. Use short bursts of compressed air, holding the can upright and keeping the nozzle at least two inches away. Checkpoint: never tilt the can or you may spray propellant onto the tray.
• Step 4: Wipe with a barely damp cloth. Lightly mist your second microfiber cloth with the distilled water and isopropyl alcohol mix. Wipe the tray’s surface in one direction, then turn the cloth to a clean side for a final pass. Checkpoint: the cloth should feel almost dry; if you can see moisture, wring it out more.
• Step 5: Let the tray air-dry completely. Wait at least 15 minutes before returning handhelds. Checkpoint: if you feel any coolness or dampness, wait longer. Moisture trapped under a handheld can cloud a screen or damage contacts.

Dust prevention between deep cleans

Dust prevention is easier than removal. Keep your display tray away from open windows, air vents, and high-traffic areas where lint and pet hair circulate. If your tray sits on a shelf, consider a clear acrylic cover or a simple fabric dust cover that you remove when showing off the collection. For trays that hold multiple units, like the Tetris Micro Player Pro Tray that includes 12 pieces, a cover is especially useful because more open slots mean more surfaces for dust to settle. A quick weekly pass with a dry microfiber cloth takes less than a minute and keeps the tray looking new.

Storage tips when the tray is not on display

If you rotate your collection or store the tray for a season, do not just put it in a cardboard box. Wrap the tray in a clean, breathable cotton cloth or a soft microfiber towel to keep dust off, and place it flat so the molded slots do not warp. Avoid plastic bags, which can trap moisture and cause mildew in humid climates. Keep the tray away from direct sunlight and heat sources, as prolonged exposure can fade printed graphics or weaken adhesive labels. For long-term storage, add a silica gel packet inside the wrapping to absorb moisture, but do not let it touch the tray directly.

Your 5-step display tray maintenance routine

1. Clear the tray completely: Remove every handheld, cable, and accessory. Work on a clean surface so you do not reintroduce dust. Checkpoint: if you skip this, you risk scratching both the tray and the handhelds.
2. Dry-dust first: Use a dry microfiber cloth on flat areas and a soft brush in slots. Never start with a wet cloth; it turns dust into mud. Checkpoint: brush gently; you should see dust lift, not fly.
3. Blow out crevices: Short bursts of compressed air, can upright, nozzle two inches away. This removes dust your cloth cannot reach. Checkpoint: if the can feels cold, stop and let it warm up to avoid propellant spray.
4. Wipe with a barely damp cloth: Use a 50/50 mix of distilled water and isopropyl alcohol on a microfiber cloth. Wipe once, then buff with a dry cloth. Checkpoint: the cloth should be almost dry to the touch.
5. Let it dry fully before reloading: Wait at least 15 minutes. Any moisture left in the slots can damage handheld contacts or cloud a screen. Checkpoint: if you feel any dampness, wait longer. Dry is safe.

Product facts that affect cleaning

• TETRIS MICRO PLAYER PRO TRAY -12 PCS: Includes 12 units of the Tetris Micro Player Pro (DGUNL-7025) in a countertop display tray. With 12 individual slots, dust can settle in each one. A soft brush and compressed air are essential to clean between units without removing them all every time.
• Pixel Player: Pixel Player is a portable handheld with 300 built-in games and includes a user guide. Because it is often stored in a tray when not in use, keeping the tray free of dust helps protect the Pixel Player’s buttons and screen from debris.
• STREET FIGHTER II CHAMPION EDITION COLLECTIBLE TRAY (PREM. ED.) -6 PCS: Includes 6 units of the Street Fighter II Championship Edition Micro Player (DGUNL-3283) in a display tray. The tray’s larger 3.25-inch screen handhelds mean more surface area to dust. A microfiber cloth that does not scratch is critical to avoid dulling the screen bezels.
