Check the exact unit and cleaning-product instructions. A product suitable for a conventional toilet is not automatically approved for a macerator installation.
What the observation means
Chemicals, sustained dosing and the possibility of a holder falling into the bowl are separate concerns. Do not assume compatibility from fragrance or colour.
A useful next step
Use only permitted products and keep loose plastic parts out of the toilet. If a block or holder entered the system, stop and seek advice. Do not add another chemical to neutralise it or repeatedly flush to disperse it.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
