Quick answer

Store retro consoles in a cool, dark, and dry place away from direct sunlight. Use UV-blocking shelves or opaque storage bins, add dust covers for daily protection, and keep cartridges in individual cases. This routine prevents plastic yellowing and physical damage.

Choose a storage location that blocks UV light

Ultraviolet light from windows and fluorescent bulbs accelerates the breakdown of flame retardants in ABS plastic, causing the yellowing seen on many retro consoles. Move your collection to a room with minimal natural light, or use blackout curtains. If display is important, opt for enclosed cabinets with UV-filtering glass or place consoles on shelves away from direct sun.

Control temperature and humidity

Heat and moisture stress plastic and metal components, leading to warping, corrosion, and mold. Keep storage areas between 60–75°F (15–24°C) and humidity below 50%. Avoid attics, basements, and garages unless you use a dehumidifier. Silica gel packets can help in small enclosed spaces, but replace them regularly.

Use dust covers for everyday protection

Dust settles into vents and crevices, acting as an abrasive and insulating layer that traps heat. A simple cloth or plastic dust cover draped over consoles when not in use reduces buildup. For active setups, consider custom-fit covers that allow cable access. Never cover a console while it is powered on.

Store cartridges and discs in cases

Loose cartridges are vulnerable to dust, moisture, and physical impact. Original cases or replacement shells keep contacts clean and protect labels. For Genesis and Mega Drive games, a dedicated cartridge case with a plastic sleeve and manual tab offers a snug fit and keeps artwork visible. Stack cases vertically to avoid pressure on connectors.

Step-by-step storage routine

  1. Assess your space for light and climate: Check where you plan to store consoles for direct sunlight, heat sources, and dampness. Use a thermometer/hygrometer to verify conditions. If you can't avoid light, invest in UV-blocking film or opaque bins.
  2. Clean consoles before storing: Dust and grime can become permanent if left on plastic. Use a microfiber cloth and isopropyl alcohol for contacts, but avoid harsh solvents on plastic. Never use abrasive cleaners that can scratch or discolor plastic.
  3. Apply dust covers or store in bins: For display, use breathable fabric covers; for long-term, use acid-free boxes with silica gel. Ensure consoles are completely dry before covering. Avoid sealing consoles in non-breathable plastic bags, which can trap moisture.
  4. Organize cartridges in protective cases: Place each cartridge in a case like the Retro Bit Cartridge Case. Store vertically in a cool, dark cabinet. Label cases for easy access without handling cartridges directly.
  5. Schedule periodic checks: Every 3–6 months, inspect for dust, moisture, or pest damage. Rotate silica gel packs and clean covers. Catching issues early prevents irreversible yellowing and corrosion.
