The Automatic Toilet Cleaner Chlorine Tablets are a convenient and effective solution for keeping your toilet clean and odor-free. These tablets are designed to dissolve slowly, providing long-lasting cleaning power. In the first few days, the color may be lighter or even non-existent, but after three days, the color will be evenly displayed throughout the water. With regular household use, one bottle of these tablets can last for 2-3 months. However, in public places where toilets are used more frequently, the usage time may be shorter. Please note that the time it takes for the color to be displayed may vary depending on the type of toilet tank. It can be as fast as 2 hours or as slow as 3 days. While the Automatic Toilet Cleaner Chlorine Tablets can remove odors and keep your toilet clean, it is important to note that they do not eliminate existing dirt. Manual cleaning is still necessary for that. These tablets are suitable for use in regular-sized toilet tanks, but may not be suitable for smaller tanks found in smart toilets. To use, simply place a tablet into the water tank of your toilet, ensuring that it stands upright. Wait for the water to turn blue, indicating that the tablet has dissolved and is actively cleaning your toilet. Enjoy a fresh and clean toilet with the convenience of these Automatic Toilet Cleaner Chlorine Tablets.
