ABSTRACT

The preliminary cleaning process for archaeological finds is a fundamental step in order to ensure the

conservation and the legibility of the artifacts. Cleansing is essential before the exhaustive study of the

archaeological material culture’s objects, but could be also one of the most dangerous procedure for the

knowledge.Anyremovalofstratifiedelements,infact,couldentailapotentiallossofinformation.

Using selective and conscientious techniques guarantees the removal of the soil residues and, at the same

time,thepreservationofthehistoricaltracesontheartifacts.

The steam cleaning technique allows selective removal of the soil and of other residues, without any impact

on the surfaces. Aims of this paper is the evaluation of the steam cleaning method, the measurement of the

interaction with the archaeological artifacts, the test of the sustainability in environmental terms and on the

healthoftherestorer.
