To Whom It May Concern:
We have many years of experience in dealing with rodent and bird borne viruses.
We have always used the most effective chemical that we can find to help keep us and our customers safe.
This chemical has been proven to kill Coronavirus along with 99.9999% of viruses and other pathogens.
The active ingredient is Benzalkinium Chloride which has been approved to kill Coronavirus by the European Centre for Disease Prevention and Control at a level of 0.05%
The chemical we use is called Steri 7 Xtra and it contains 0.086% of Benzalkinium Chloride.
This link is the Technical Sheet for Steri 7 Xtra:
Steri 7 is a near odourless chemical which can be fogged in buildings and vehicles and is non bleaching. We also have a nicely perfumed (floral) version in stock.
The application via fogging puts a fine mist over every surface and is dry in a short time. This is also more effective than using cloths etc. as the chemical is blown onto all surfaces in three dimensions. Re-entry time to treated rooms is one hour.
We have a variety of fogging machines, one of which is shown here on a BBC video. (We have rather more advanced PPE that this chap!). We also have the excellent Exodus ULV (ultra-low volume) fogger machine from Killgerm Chemicals for larger spaces.
We hope that this helps answer your questions but if you would like to know anything else please ask.
