Adora disinfectants are not inactivated by organic matter unlike some disinfectants. Our disinfectants are not affected by hard water and do not leave residue on the surface after application. Adora disinfectants are not corrosive and are not skin, eye or respiratory irritants. Other benefits of Adora disinfectants are that they are not toxic either by skin absorption or inhalation and have long shelf life after dilution.
