Lysol Automatic Toilet Bowl Cleaner Complete Clean Tabs is the only toilet bowl cleaner that provides antibacterial protection built directly into the hang-up hook, effectively resisting odor-causing bacteria. This innovative design eliminates the need to touch germy, dirty hooks when replacing the tabs. Each tablet lasts an average of 4 weeks, gradually dissolving to release a fresh, clean scent and powerful cleaning agents that keep your toilet bowl Lysol clean and fresh with every flush. The product comes in a convenient 2-pack, ing up to 8 weeks of continuous cleaning. Its flexible hang-up hook adjusts to fit any type of bowl rim, making it easy to place the tab in the optimal position. For results, hang the tab towards the back of the bowl, slightly right of center, avoiding the direct path of the refill water to prevent splashing while still allowing the tab to clean effectively with every flush.
