Raypath cleaning method – a project which is intelligent economy-wise and responsible ecology-wise – consists of not having to use any detergent. In fact, just a small quantity of water (hot or cold) and high quality microfiber sponges with a memory and nano silver are enough to clean all washable surfaces of a hotel (rooms, public spaces such as bar, lobby, wellness space, etc.), a school, a restaurant, an office, a factory, etc. while respecting the imposed bacteriological standards (HACCP). By « washable surfaces » means both large surfaces such as walls, ceilings and flooring (type: tiles, marble, parquet, linoleum, etc.) that small surfaces such as sinks, bathrooms, windows, stainless steel tables, kitchen, toilets, furniture, office, computer screen, keyboard, etc. The dirtiness is kept in the sponge and there is no transmission of this dirtiness caught. Moreover, given that the dirtiness is removed mechanically thanks to the structure of the micro fiber and no with a detergent, there is no anymore layer of the detergent on the surfaces. Of course, dirtiness sticks much less to the surfaces which are cleaned with our method than those which are covered with chemical products. The mission of the company has been the development of environmental awareness on the basis of the application of RAYPATH Cleaning Technology, based on innovative textile technological solutions, facilitates such an effective cleaning, although without the need for hazardous detergents. The formation of the entire maintenance staff adopting Raypath method is systematically provided from the Raypath team. The goal is to support all staff (managers and maintenance staff) and make them aware that this method certainly requires a change but a change that, at the end, is more efficient, more sustainable & ecological, healthier for the users and more economical from a financial point of view in comparison with a traditionnal method.
