Keeping the glass on your toy crane machine clean is essential for clear visibility and an attractive appearance. First, unplug the machine for safety. Use a soft, dry microfiber cloth to gently remove loose dust and debris from the glass surface. For fingerprints and smudges, lightly dampen a portion of the cloth with water or a mild, ammonia-free glass cleaner specifically designed for plexiglass or acrylic. Avoid harsh chemicals like ammonia or abrasive cleaners, as they can cloud or damage the material. Wipe in a gentle, circular motion. For stubborn marks, a small amount of diluted isopropyl alcohol can be effective. To address minor scratches, a specialized plastic polish can be applied following the product instructions. Always finish by drying the glass thoroughly with a clean, dry microfiber cloth to prevent streaks. Regular, gentle cleaning will keep your toy crane machine looking its best for years of fun.
