Keeping the inside of a toy crane machine's glass clear is essential for visibility and player engagement. Fogging, or condensation, occurs when warm, moist air inside the cabinet meets the cooler glass surface. To prevent this, start by ensuring proper ventilation. Check that any built-in vents or fans are clean and operational; they help equalize temperature and humidity. For persistent issues, apply a commercial anti-fog spray or gel specifically designed for acrylic or glass surfaces. Clean the glass thoroughly before application. Alternatively, use moisture-absorbing desiccant packs or silica gel canisters placed discreetly inside the machine to reduce ambient humidity. Regularly inspect seals around the glass and door for gaps that might allow humid external air to enter. Maintaining a consistent environment temperature around the arcade area also minimizes drastic temperature differences that cause fogging. With these simple steps, you can ensure a clear view of the prizes, enhancing the player experience and the machine's appeal.
