toilet self cleaner

Common types include brush systems with built‑in cleanser tablets, tank/drop‑in tablets, under‑rim gel stamps, powdered or foaming sachets you pour into the bowl, and chemical‑free tank magnets.

Package sizes vary widely: single brush kits; small packs of tablets (for example, 5 tablets); and multi‑packs that commonly range from about 4 up to 15 or 24 tablets/discs.

Replaceable brush heads contain a solid cleanser tablet that activates with water while you brush. Many systems include a caddy or holder designed so you don’t need to touch the dirty brush head when replacing it.

Common application methods include stamping gel discs under the rim, dropping tablets into the tank, pouring powder or foam sachets into the bowl, brushing with heads that contain embedded cleanser tablets, and placing magnets into the tank.
