How it works

Any Questions?

Cert. can be used on most hard surfaces in kitchens, bathrooms, glass, floors and wooden surfaces. See a full list of surfaces Cert. has been tested & tried on our FAQ page.

Yes! A diluted tablet of Cert. has an almost-neutral PH level, meaning it is safe to use in a home with pets. Like with any cleaning product, we don't recommend spraying directly onto a pet or pet bedding.

Cert. tablets come in plastic-free, recyclable packaging. Spray bottles & mops also arrived in recyclable packaging.

Cert bottles, should you need to dispose of them, are widely recycled, although we would encourage Cert. customers to reuse and refill.

Yes, Cert. is tested & proven to be effective against all enveloped viruses, including SARS-CoV-2 and all variants of this, as well as many other well-known viruses found commonly in care homes and hospitals.

That's why hospitals around the world trust our tablets to keep their settings clean and safe.

Cert. is made & manufactured by Hydrachem, a trusted supplier to the NHS for over 50 years. Hydrachem manufactures 95% of the sanitising products used by the NHS, via several distributors who trade under their own label brands.

The Cert. formula is the same formula used by the NHS, under a variety of different brand names.

Once dissolved, the disinfectant in Cert. responsible for killing Covid-19 is active for 7 days.

After 7 days, the spray will become less effective at destroying viruses. Cert. will still provide a powerful anti-bacterial clean for several further days, as the strength of disinfectant needed to kill bacteria is much lower than viruses.

Did you know?
Diluted bleach solutions are only active for 24 hours; Cert. is active for 7 days and is far safer to store, prepare and use.

Yes, Cert. has been tested and proven to kill all enveloped viruses including SARS-CoV-2 after just 60 seconds on a surface.

Cert. complies with United Kingdom Health Security Agency's cleaning principles on how to keep surfaces virus-free, and has been tested to European standards.

No. Cert. has been tested and proven to destroy SARS-CoV-2 and other viruses after just 60 seconds on a surface.

We recommend waiting 5 minutes to ensure all other bacteria is destroyed - just like most other anti-bac surface cleaner also recommends if you read the small print.
