Cleaning calcium build-up from plastic, ceramic, and glass water dishes and bottles is crucial for hamsters. Follow this simple method: mix equal parts lukewarm water and vinegar, soak the affected areas for 15-30 minutes, scrub lightly, and rinse with water. Use a tray to contain spills if cleaning multiple items. If the build-up persists, increase vinegar concentration or extend soaking time. Regular maintenance ensures clean water access and prevents potential health risks for hamsters. Remember, a hydrated hamster is a happy hamster, so keep those water containers squeaky clean
