PROBLEM 01
Limescale & mineral deposits
Define deposit severity, bowl material, water conditions and acceptable contact time.
Formats to discuss
Clinging acid liquid · heavy-duty gel · targeted powder
Start with the toilet problem
The right format follows the cleaning job.
A familiar product name does not define the deposit, use condition or evidence needed.
Use this map to frame the OEM discussion. It is not a remote diagnosis or a universal formula recommendation; surface compatibility, final composition and intended claims still require project-specific review.
PROBLEM 02
Rust-coloured staining
Distinguish iron-related staining from other deposits before selecting a chemistry and claim route.
Formats to discuss
Oxalic-acid direction · targeted liquid · controlled gel
PROBLEM 03
Organic soil & visible residue
Clarify soil type, cleaning frequency, mechanical action and the expected visual cue during use.
Formats to discuss
Foam · mousse · brush-free liquid · gel
PROBLEM 04
Toilet odour & after-clean perception
Describe the odour problem, desired fragrance character, release moment and intended freshness language.
Formats to discuss
Fragranced cleaner · foam · gel · continuous-care format
PROBLEM 05
Under-rim & vertical coverage
Set the target application area, bottle geometry, cling profile, dwell time and rinse expectation.
Formats to discuss
Angle-neck liquid · clinging gel · targeted mousse
PROBLEM 06
Routine flush-by-flush maintenance
Define placement, flush conditions, service expectation, colour release and user handling.
Formats to discuss
Rim block · cleaning tablet · continuous-care dose
Do not stop at the stain
The user experience continues through scent, dose and rinse.
Two cleaners aimed at the same deposit can feel entirely different in application. The OEM brief should also cover bottle handling, cling, visual cues, fragrance, dwell time and what the user sees after flushing.
