Experiments on surface dry cleaning with the use of an electric field are in progress. Some of their results, concerned with time dependence of probability of particle resuspension are discussed in this report. The results of optical and scanning electron microscope surface studies are used for the analysis of observed phenomena.It was shown that even one cycle of water condensation on the glass surface leads to dramatic increase of adhesive force, so that the probability of resuspension drops to zero for loess particles even as large as 100 μm. The high level of adhesion is conserved after water evaporation from the surface.But even under conditions of low relative humidity the efficiency of dry cleaning decreases in time. Particles of loess on the glass surface demonstrate typical time for saturation of the order of 10 min. This effect strongly depends on particle size, being especially pronounced for particles less than 10 μm. For particles of this size it is shown that both resuspension of mono-particles and splitting of agglomerates take place. It is shown that for the time delay between the moments of particle deposition and of its resuspension shorter than 1 min the efficiency of dry cleaning becomes close to 100%, including sizes lower than 10 μm (the protection mode ).
