Conclusion:
Banishing the black circle around your toilet requires a combination of thorough cleaning, prevention measures, and regular maintenance. By understanding the causes and implementing the methods mentioned above, you can enjoy a clean, white, and mold-free bathroom. Remember, it’s essential to address the issue promptly to maintain a hygienic and visually appealing space for yourself and your family.
