A persistent odour problem in a men’s arrivals washroom at one of the UK’s busiest airports was resolved in just two weeks, no washroom refurbishment, no extended downtime, just a targeted sustainable treatment programme.

Despite a full facilities management team following regular cleaning routines, the source of the smell kept coming back.

This case study breaks down how camera inspection revealed the real cause (uric acid scale build-up deep in the pipework), how URIZAP Shock and ongoing URIZAP dosing eliminated it for good, and what changed for both passengers and the cleaning team on the ground.
