Two toilets of the same model have different cleaning issues (persistent black gunk in rim jets and a hard-to-reach siphon jet stain) that cannot be fully cleaned with standard cleaner and brush, and in-tank cleaning tablets damage flappers, requiring a plumber-safe alternative.

Existing solutions either don't fully clean the rim jets and siphon jet stains (manual cleaning) or cause damage to toilet flappers (in-tank pucks).
