Abstract
The present invention relates to a method of purifying solvents of the type used in dry-cleaning machines, comprising submitting the polluted solvent only to a filtration step by filtering the solvent through a filter which comprises a filter powder capable of retaining greases and permitting, when saturated, the separate draining of the purified solvent and of the filter powder loaded with impurities.
