toilet deodorizer

Common types include gel stamps/discs (pressed under the rim), tank or drop-in tablets (dropped into the toilet tank), before-you-go sprays (spritzed into the bowl before use), and pre-measured dissolving sheets (dropped into the bowl). Application is simple: press or stick gel discs under the rim, place tablets in the tank, spray a short burst into the bowl when needed, or drop a sheet into the bowl where it dissolves.

Lifespans vary by format: gel stamp discs are often labeled to last up to about 12 days each; many drop-in/tank tablets advertise service for several weeks (around 4 weeks for some); certain bleach-based tank tablets claim up to about 4 months per tablet (packs may extend total coverage); and small travel sprays are rated by use count (for example, about 100 uses). Actual duration depends on product formulation and frequency of flushing.

Common scents include floral, rain/rainshower (Rain Clean), fresh/fresh air, jasmine, pear, bamboo, sea minerals/sea spray, lemon or other citrus, lavender, and an "original" or signature scent.

Products typically advertise odor elimination or neutralizing, stain and limescale prevention or removal, brightening/cleaning with each flush, and in some cases sanitizing or germ-reduction claims.

Many tank tablets show a continuous colored flush (often blue) while active. Instructions typically advise replacing the tablet when the color fades or disappears.
