How it Works

By slowing the build-up of proteins, yeasts, sugars and bio-films on the inside of your beer lines, StayClean products reduce the need for frequent beer line cleaning.

Monthly beer line cleaning

​Moving from weekly to monthly line cleans will cut a bar’s line cleaning costs by 75%.

Optimising cellar conditions can stretch the period between cleans up to 6 weeks, offering even greater savings.

StayClean products never come into direct contact with the liquid in the lines or the kegs, so they cannot affect the quality, taste or pour of your products.

Patented sound waves

Our products use in-house software to generate a phased series of low frequency electromagnetic radio waves.

Employing high quality antennae cables coiled around the exterior of the beer pipe, the digital wave field is passed through the liquid in the line, inducing a small electrical charge in the molecules of the beer.

This action reduces the level of attraction between molecules in the liquid, slowing down the process through which they clump, cling to the inner surface of the beer line and ultimately begin to taint the flavour of your beer.

Clean as a new pin

In addition to slowing the build-up of new contaminants, the digital wave field of StayClean devices also acts to loosen any existing bio-films and beer stone deposits in the lines.

For this reason, we always advise a thorough deep clean of the lines before installation.

What really matters is that StayClean products work and have been helping pubs, clubs, bars and hotels to save money on their line cleaning for more than 25 years.

Warwickshire pub fined £140k for food hygiene breaches.
The pub remains open - but is not currently serving food.
Hopefully their beer lines are nice and clean?

A very successful coffee morning on Wednesday helped raise over £300 for a local Samaritans charity. A big thank you to all involved and your support.

How much???
£96 for a pint and a half.
If this was draught, their waste costs would make 'em cry!

Apparently supply is finite - at just shy of £100 for 750cl, you'd think it would be demand.

Fancy a really quiet pint - escape from the modern world + try the @samsmithsbeer Commercial Hotel in Knaresborough, where mobile phones and other devices are banned:
