At a time when health concerns within care and residential homes have never been higher, it’s essential to choose and correctly utilise a high quality, non-toxic disinfectant and cleaner. There are some additional concerns over the effectiveness of the disinfectants currently used to deal with emerging microbes in care and residential homes, such as coronavirus, C.difficile spores and MRSA. Chlorine and quaternary ammonium compounds (QAC)-based products are commonly used to disinfect surfaces in care and residential homes. However, the use of chlorine results in the formation of toxic, halogenated by-products upon contact with organic material, which is damaging to the user, the environment, and any soft furnishings it comes into contact with. QACs have notoriously poor virucidal, sporicidal, and fungicidal properties at concentrations safe to the user. It also performs very poorly in soiled conditions. Peracide works at lower concentrations than chlorine or ammonia based cleaners and is less hazardous for those using it as a result. Peracetic acid (PAA) produces safe by-products, acetic acid and oxygen, in decomposition and does not therefore leave behind toxic residues that will affect the final product or the waste management of such products. It has proved advantageous as a disinfectant and sanitiser in the residential care industry, with it proven to be highly effective against bacteria; including the likes of MRSA and spore forming bacteria, such as C. difficile, along with producing outstanding efficacies against viruses, such as polio.
