SELFCLEAN Technology

Our unique antimicrobial barrier technology provides unrivalled cleaning and disinfection armoury in the fight against infection and potential outbreaks.

Trains & Public Transport

In a world where we are fighting a losing battle against more resistant bacteria and viruses, the need for new technology to clean and disinfect our public transport environments has never been greater.

Public transport, which includes trains, buses and coaches transport millions of customers each day. Public transport environments need to be kept clean but can also become highly contaminated from potentially harmful microbes because of the shear numbers of passengers in a relatively small environment. This means that microbes can easily be transferred through touch points such as grab rails for those standing, seating and the proximity to a number of frequently touched surfaces. The potential risk for the transmission of harmful microbes is therefore of concern from surfaces.

Although public transport vehicles need to be kept as clean as possible for aesthetic reasons the requirement for the environment to be as safe as possible from harmful microbes and potential global pandemics is paramount.

“Cleaning alone does not kill potentially harmful microorganisms such as Norovirus the “winter vomiting” virus, which can strike at any time”

Most normal cleaning products do not contain any form of biocide relying on physical removal of soils and microorganisms as cleanliness is the main objective. Even if they do contain some form of biocide, none can compete with the long-lasting effect of using Goldshield® known as our long-lasting “residual protection”.

Any surface in public transport that is i contact with passengers especially hands becomes a potential source of cross-infection. Surfaces can also become contaminated from passengers shedding microbes or those originating from respiratory infections. This contamination then poses a risk to other passengers and staff responsible for both driving and provide services to those passengers.

Goldshield®’s advanced technology contains a range of liquid products that can both clean and disinfect. Our products leave an invisible layer which is completely safe to passengers and staff but carries on killing harmful microbes for potentially days after a single application.

Why should you use our products?

SELFCLEAN / Goldshield® is a silicone based polymer that for many years was used in the treatment of textiles to provide both hydrophobic and antimicrobial properties. Our R&D team were able to adapt this technology to provide a water based solution and a molecule capable of forming a covalent bond with hard and soft surfaces. This meant that we now had a biocidal product capable of being used on hard and soft surfaces that provides a durable antimicrobial mono-molecular layer protecting the surface for extended periods.

Disinfectants of which there are many, are important to control pathogenic or harmful microorganisms as if there are any on a surface potentially capable of causing infection, removing them by cleaning and killing them by disinfection minimises that risk. Many products contain both detergent and disinfectant and are termed sanitisers. Products containing powerful agents such as chlorine or more recently chlorine dioxide, have excellent microbicidal properties but can be damaging to surfaces and can have health & safety issues depending on their concentration.

SELFCLEAN / Goldshield® does not replace cleaning as this remains an important part of the process and as an acknowledgement of this we have a sanitiser in our range that both cleans and disinfects. A surface has to be thoroughly clean before the application of SELFCLEAN / Goldshield®.

The reason cleaning is important is that during the course of the day surfaces become “dirty” and need to be cleaned to remove this soil and for aesthetic reasons. Moreover, if surfaces were not cleaned regularly even with microfiber and normal detergent soils such as body fat (the “smudge” we see on glass) will build up and both protect and provide nutrients for microorganisms held within.

SELFCLEAN / Goldshield®’s covalent bonding means that it remains active even if the treated surface is cleaned by physical and even chemical action.

SELFCLEAN /Goldshield® has a product that:

  • Is not removed by routine cleaning
  • Enhances cleaning
  • Provides a surface that is microbiologically clean in excess of 24 hours


SELFCLEAN's liquid spray persistent residual antimicrobial barrier protection technology.

  • The microbe lands on the treated surface
  • The microbe is then pulled onto the molecule by strong electrostatic forces
  • The microbe is then pierced and killed
  • The analogy is “a bed of molecular nails”

SELFCLEAN's technology forms a covalent bond which allows it to remain affixed to any hard or soft surface including textiles. The surface is positively charged generated by a nitrogen molecule, which pulls in negatively charged microbes. Through a long carbon chain, this unique assembly penetrates the cytoplasmic membrane physically stabbing the cell releasing ions, denaturing proteins and causing cytoplasm to leak so the cell is then destroyed. This renders the microbe dead and incapable of any adaption.

SELFCLEAN uses a technology that not only cleans and disinfects any surface but also protects it from microbes that land on the treated surface once it is dry.
