Keeping the plastic dome of your toy crane machine clean is essential for clear visibility and hygiene. First, unplug the machine for safety. Use a soft, dry microfiber cloth to gently remove dust and loose debris. For fingerprints or smudges, lightly dampen part of the cloth with a mixture of mild dish soap and warm water. Wipe the dome gently in a circular motion, avoiding excessive moisture that could seep into seams. Immediately dry the surface thoroughly with a clean, dry part of the microfiber cloth to prevent streaks. For disinfecting, you can use a cloth lightly sprayed with a 70% isopropyl alcohol solution, but avoid harsh chemicals or abrasive cleaners that can cause clouding or scratches. Never spray liquid directly onto the dome. Regular, gentle cleaning will maintain the dome's clarity and keep your crane game looking its best.
