My DMSO-d₆ appears to be a solid. What can I do?

Dimethyl Sulfoxide (DMSO) has a melting point of 18℃, freezing close to room temperature. Sometimes when it is delivered it will be in a solid state. To return the material to a liquid state, thaw it in a warm water bath. Care must be taken to prevent water contamination.
