Actone wash?
Failing that, freebase it, take it up in the minimum volume of HOT toluene, xylene or naptha. Wash with cold water a couple of times. This will remove the epsom salt, which will remain in the aqueous phase. Gas with HCl, precipitating the meth. Filter off the goods, then partially evaporate, until perhaps a quarter of the volume of solvent remains, this can be put in the freezer, to freeze-precipitate remaining meth, if any (lowering the temperature lowers the solubility of dissolved compounds, resulting in their precipitation)
And then lastly, evaporate your solvent completely, to get any last traces of speed out of there.
Option 1. Ignore it; epsom salt is just magnesium sulphate and is basically harmless.
Option 2. Acid/base extraction.
Acetone washes won't do anything.

Acetone and Isopropanol.Depends on the solvent in question.
Speed = Slang used predominantly for (meth)amphetamines, however it is not uncommon for "speed" to be used in reference to any stimulating substance. In tis case, "speed" is referring to meth.
I don't mean to sound crass, but the fact that not only were you unaware of what "speed" was, but you could not figure it out using basic reasoning means that you needn't worry about anything in this thread. TBH, I would caution against using any drugs with spending some time doing extensve research. Erowid.org is a great place to start. Again, my intent is not to be condescending, but this is the most rudimentary of drug knowledge. Please visit Erowid and read all you can understand before getting high.
