Verifying that clean really is clean

If you follow us on social media, you might have come across the ATP readings we sometimes post. But what are ATP tests, and how do they work?

So what is ATP?

ATP is short for Adenosine Triphosphate, a molecule found in and around living cells. In fact, it’s the universal energy carrier in all living things.

Measuring something really, really tiny

By adding a reagent containing the enzyme luciferase, the amount of ATP in a sample can be quantified using a sensitive luminometer. Basically we’re measuring how much light the sample is producing – all thanks to the enzyme’s bioluminescence.

How does it help with cleaning?

Cleanliness at our fingertips, with our portable ATP monitoring systems

By knowing the ATP reading, we have a basic indicator of cleanliness. After each sanitising treatment we will take random ATP tests. No ATP — no organism in the sampled area. It’s a simple rapid test giving a result in 15 seconds that can be used by anyone at the point of use / point of care.

Monitoring cleaning standards

The system is well proven and has been established for >30 years in several industries e.g. catering and healthcare. The system has been evaluated by DH Rapid Review Panel (2009) and given the highest level recommendation for use (level 1).

Low scores are better!

The scoring system is as follows:

  • 0 -11 RLU the item is considered clean
  • 12 – 30 RLU the item is acceptable but requires cleaning
  • Anything above 30 RLU is a fail and the larger the reading the larger the contamination is evidenced.

Testimonials

We really like the quality of the work you do and want to build a long standing relationship with you.

We have been using Clean-n-bright for 2 years now and I’m very happy to say that I would recommend them.  We have had no issues with the standard of cleaning, they are quick and efficient, coming in before we open to the public so we don’t have any problems with H&S and as well as windows have cleaned our gutters very effectively.  On top of this the workers are polite and friendly which makes a big difference.
