Keeping the viewing window of your toy crane machine clean is essential for clear visibility and an appealing look. First, ensure the machine is unplugged for safety. For light dust, use a soft, dry microfiber cloth to gently wipe the surface. For fingerprints or smudges, slightly dampen a part of the cloth with distilled water or a mild, non-abrasive glass cleaner sprayed onto the cloth—never directly on the window. Gently wipe in a circular motion. Avoid harsh chemicals, ammonia-based cleaners, or paper towels, as they can scratch plastic surfaces or leave residues. For the exterior cabinet, use a separate damp cloth. Finally, dry the window thoroughly with a clean, dry section of the microfiber cloth to prevent streaks. Regular, gentle cleaning will keep your crane machine looking its best.
