Frequently asked questions
Here you will find frequently asked questions about our Evogen Professional products and the science behind them. If you do not find your answer, please feel free to contact us.
Conventional cleaners only work whilst the surface is wet, i.e. during the cleaning process itself as they need water to wash the dirt away. Conventional cleaners also do not work so well if the dirt is old or is absorbed deep into the surface. A biological cleaner will continue to work after the cleaning is finished, as the bacteria will remain on the surface and continue to grow. The bacteria are microscopic and can penetrate that deep lying dirt, breaking it down into easier to remove materials.
Yes Evogen Professional will give very good cleaning and odour control results on soft surfaces. The material only needs to be damp for the bacteria to get working, so do not soak or flood the area. As with all cleaners, test the product on a hidden part of the soft surface before proceeding.
Yes Evogen Professional also works outside. For stubborn soiling or lager areas consider the Evogen Professional Exterior Hard Surface Cleaner.
The bacteria will remain on the surface after application and will continue to work long after the cleaning is finished, breaking down the dirt. They only stop when all of the food has been used up, i.e. the area is clean.
The product bacteria will remain on (and in) the surface and they will continue to work for as long as there is food for them and the area is still damp. Therefore they can remove stubborn soiling over a few days or a few applications that even the strongest chemical products can never touch.
A lot of odours are caused when environmental microorganisms break down various materials releasing foul smelling nitrogen and sulphur containing chemicals. The beneficial bacteria in Evogen Professional work by a different way, as they break down the food they use what is released for cell growth, generating millions more “mini cleaning machines” and removing the source of the odour, not masking it.
Conventional deep cleaning involves a lot of scrubbing, abrasion, high pressure or steam cleaning. All of these processes cause wear and degrade the surface, actually encouraging re-soiling. The bacteria in Evogen Professional break down the soil into easier to remove materials in a gentle and non-corrosive way, so less scrubbing is required and surfaces are not degraded.
As the bacteria continue to work 24/7, better results are obtained without frequent cleaning. Once the bacteria have become established, cleaning frequency can be reduced, saving £££££s on labour.
In theory, yes they can, they will do a great job of removing food based materials. However, in practice we do not recommend bacterial product for food preparation areas as many of the tests used to see if such places are cleaned and disinfected cannot differentiate between good and bad bacteria and may result in high readings and QC fails, even though the bacteria in Evogen Professional are totally safe.
The bacteria in Evogen Professional are all Bacillus species isolated from nature and they have a long history of human exposure and low risk. If you want to know the legal basis for this then we state “microorganisms in this product are all Group 1 (i.e. considered unlikely to cause human disease) according to EU Directive 2000/54/EC and related legislation”. In the US, the species we use are have a status known as Generally Regarded As Safe (GRAS).
Many products make a big issue about being biodegradable, but in Europe all surfactants must be at least 60% biodegradable within 28 days as specified in Annex III of the EU Detergents Directive (Regulation 648/2004). When selecting raw materials, we look much deeper than that, specifying a much higher percentage or shorter time than the minimum standard for biodegradability and also taking into consideration aquatic toxicity and behaviour and fate in the environment.
