The science behind Cert.

How does Cert. destroy viruses?

The main biocide ingredient in Cert. is NaDCC, which is a chlorine-like disinfectant used globally for the disinfection of water, including drinking water.

Cert. cleaning tablets contain 1000 parts per million NaDCC, which is the dilution level recommended by Public Health England needed to destroy COVID-19.

When combined with a detergent, this formula is powerful enough to destroy the Covid virus within just 60 seconds on a surface, and many other viruses within just 5 minutes.

This makes Cert. SO much more than just a bog-standard antibacterial spray, which have much lower levels of disinfectant.

This is what makes Cert. so mighty. Welcome to the new standard of cleaning.


Public Health England are very clear about what can destroy COVID-19 and other viruses. They say you should use: “a combined detergent AND disinfectant solution at a dilution of 1,000 parts per million available chlorine (ppm”
Cert.’s Predosed tablets ensure you meet this 1,000ppm requirement. Its easy drop-in-and-dissolve disinfectant and compatible detergent, ensure you can thoroughly clean AND disinfect in 3 easy steps.
This little, but powerful and effective cleaning tablet kills 99.99% of bacteria and viruses including COVID 19.


What is Cert. made of?

Cert. is made up of just three components; a disinfectant, a detergent and an effervescent.

Sodium Dichloroisocyanurate, or NaDCC

This is the biocide, or disinfectant, needed to kill Covid-19 & Viruses. In the correct dose, it is safe on skin, surfaces and around children & pets.

It’s a chlorine-like disinfectant that is used globally at different doses for treating contaminated water, including water for human consumption.

Detergent (Surfactant)

A combination of disinfectant and detergent is needed to effectively kill viruses & bacteria. The Cert. formula delivers a unique & safe combination of the two.

An effervescent base

Bubbles! To allow Cert. to dissolve quickly in water.

Tested and Proven

You can feel safe in the knowledge that Cert. surface spray has been tested and proven to European standards and complies with Public Health England guidelines on how to kill Covid-19 on surfaces.
