Biofilm and debris can be removed from the interior and exterior surfaces of small bore tubing by passing an aqueous cleaning solution of water, one or more surfactants and preferably a source of hydrogen peroxide, optionally including small inert solid particles, together with a gas under pressure, to create a turbulent flow within the tubing that loosens the biofilm and debris so that they can be flushed from the tubing. When the exterior surfaces of tubing are to be cleaned, the tubing is inserted in a sleeve fitted with an adaptor that provides a pressure-tight seal between the tubing and the sleeve.
An aqueous cleaning solution that removes biofilm and debris from the walls of tubing for dental and medical uses comprises water and a surfactant admixed with air under pressure.
A method of removing biofilm from the interior surfaces of tubing exposed to aqueous solutions comprising mixing an aqueous solution of water and a surfactant with a gas under pressure so as to form a turbulent mixture in said tubing for a time sufficient to loosen said biofilm, and flushing the tubing to remove the biofilm.
In a dental unit comprising a source of compressed air, a source of water, and a small bore tubing that passes said water and air to a nozzle for delivery of the pressurized air and water to a patient, the improvement which comprises a mixing container for mixing a cleaning solution of water and a surfactant with the pressurized air and delivering the pressurized cleaning solution to said tubing.
