Free to clean

A new liquid, branded Wetrok Libero and distributed through Jigsaw Cleaning Systems, is made from plant oils and is said to be effective in all cleaning situations across floors and other surfaces.

Libero is Italian for free, and the liquid is free from chemicals including soap, complexing agents, solvents, salts, alcali, acid, phosphates, colouring and perfume.

Professor Daniel Berti of Wetork said:"This new product is a plant-based microemulsion.

Milk is an emulsion of water and droplets of milk fat, that is why it cleans dirt that is soluble in water as well as dirt that is soluble in oil. Its droplets of plant-based oil are extremely small and therefore the cleaning power is much higher compared to milk.The difference is the absence of any chemical ingredients usually found in cleaning products, and for this reason it cannot be judged as an eco-label under certification laws." James Blackhurst, managing director of Jigsaw said:"This liquid is even harmless if you happen to ingest some of it."
