ABSTRACT:
A method of cleaning a hollow article comprises a step of introducing an oxidizing working gas into at least an interior portion of the hollow article, while a sub-atmospheric pressure is being maintained therein. Then, an electric field is applied, so as to convert the oxidizing working gas within at least the interior portion of the article into a low temperature plasma. This leads to oxidizing substances situated at least within the interior portion of the hollow article.
