I've got some tin tetrachloride which was originally in an anhydrous state but has absorbed a fair amount of moisture. As a result the crystals have become sticky and clumped together resulting in hard impacted lumps.

How would I go about processing it to revive it to its original form as it was when it was sold?

If Sncl₄ gets wet it willbe form SnO₂. So there is no way back. The only thing could be do do a destillation in vaccum to get rid off the tinoxides.
