Sodium hydroxide is frequently used in the process of decomposing roadkill dumped in landfills by animal disposal contractors. Due to its low cost and availability, it has been used to dispose of corpses by criminals. Italian serial killer Leonarda Cianciulli used this chemical to turn dead bodies into soap. In Mexico, a man who worked for drug cartels admitted disposing over 300 bodies with it.
Just thought I would throw this in there just in case you were looking for other things to do with it.......I mean after all MOST people have a mother in law.
