To the non existent "ice" and "dust"?????
What the hell are you on about now? They've seen dust. They've seen what is almost certainly ice. They've detected water vapour and CO2 and various other gases. They excavated H2O from Tempel 1.
So no, there is plenty of evidence for ice and dust. Including the density, which isn't that of rock, by the way.
What we see no evidence of is electric woo, or enormous increases in the solar wind flux to create the observed gases.
As I keep saying, you have zero evidence for this crankery.
