ABSTRACT:
The inventive subject matter relates to methods for reconditioning a barrel previously used for containing a substance, comprising the steps of determining cutting parameters specific to the barrel material to provide controlled cutting of the barrel material; removing a desired depth of the barrel material using an automated high pressure water cutting device; testing for a remnant of the substance using a sensor device; optionally spraying with a dissolving agent; and repeating the steps of removing and testing upon detecting the presence of the substance in or on the barrel. Additionally, the inventive methods comprise applying a liquid to the wood of the reconditioned barrel to control evaporation of the barrel contents.
