If you pick up some MgSO4 (magnesium sulfate) from Walmart or Home Depot (or even better, your local hardware store or brewing supply store) and add it to your isopropyl alcohol, you'll have anhydrous isopropyl alcohol, which would be perfect for your needs. If you can't, for some reason, get a hold of MgSO4, you could use calcium hydroxide, though you could also use your ISO as is, the only downside being residual water in your reclaim which will prevent you from getting a purer and more solid/less oily residue.
Everclear has the added benefit of being foodsafe, though either solvent should do the job. I typically swish small amounts of solvent in the rig repeatedly, combining each pull in a pyrex pie dish from which I let the solvent evaporate over a bowl of freshly boiled water until the pyrex is coated in a film of crystalline product.
