If your hot tub water keeps going cloudy or smells even after cleaning, biofilm is likely the cause. This hidden layer of bacteria builds up inside your hot tub’s pipework and jets, making it resistant to chlorine and standard sanitisers.
Our professional hot tub deep cleaning and biofilm removal service in Wirral removes this buildup properly—restoring clean, safe water and preventing ongoing issues.
What Is Biofilm in a Hot Tub?
Biofilm is a sticky layer of bacteria that forms inside your hot tub’s plumbing system. It protects harmful microorganisms from chlorine and sanitisers, allowing them to grow and spread.

Why Standard Cleaning Doesn’t Work
Biofilm is resistant to chlorine and standard sanitisers, which is why professional removal is required.
Most cleaning only treats the water—not the inside of your pipework. Biofilm hides in these areas and quickly re-contaminates your tub.
How Often Should You Deep Clean a Hot Tub to Remove Biofilm?
Biofilm can build up even in well-maintained hot tubs. Most hot tubs benefit from a professional deep clean every 3–6 months depending on usage. Regular cleaning helps remove hidden bacteria, maintain water quality, and prevent recurring issues.
