Abstract
The invention includes a method of reducing the microbial population on a item comprising, in whole or in part, porous material. The method includes contacting the porous portion of the item with both a surfactant and gaseous ozone, preferably in a sealed container.
Claims19
A method of reducing the microbial load on an item comprising porous material, said method comprising:
- contacting said porous material with an aqueous solution containing a surfactant, thus wetting the porous material;
- and
- contacting said wetted porous material with a combination of ozone and gas for a period of time sufficient to reduce the microbial load on said item, said gas selected from the group consisting of air, oxygen, and mixtures thereof.
A method of reducing the microbial load on an item comprising porous material, said method comprising:
- contacting said porous material with an aqueous solution containing a surfactant, thus wetting the porous material;
- placing said item into a chamber, said chamber having an interior portion in controllable fluid communication with an ozone source, said ozone source actuatable externally to said interior portion;
- providing an air tight seal between said interior portion and the atmosphere exterior to said interior portion;
- and
- actuating said ozone source, causing ozone to enter said interior portion, thus contacting said wetted porous material with a combination of ozone and gas for a period of time sufficient to reduce the microbial load on said item, said gas selected from the group consisting of air, oxygen, and mixtures thereof.

A method of reducing the microbial load on an item comprising porous material, said method comprising:
- contacting said porous material with an aqueous solution containing a surfactant, thus wetting the porous material;
- placing said item into a chamber, said chamber having an interior portion in controllable fluid communication with an ozone generator capable of generating ozone from the air present in said interior portion, said ozone generator actuatable externally to said interior portion;
- providing an airtight seal between said interior portion and atmosphere exterior to said interior portion;
- and
- actuating said ozone generator, thus providing ozone in said interior portion, and contacting said wetted porous material with ozone for a period of time sufficient to reduce the microbial load on said item.
