Eucalyptus oil is the best product for removing the sticky gum left behind 
from price tags and other glue backed lables.

> Oil distillation

> The eucalyptus oil distilleries of Central Victoria
> are basically the same and each has the following
> components: steam supply, distilling vat(s),
> connecting piping, a condenser, and an oil-collecting
> vessel. In most of the stills the distilling equipment
> is antiquated and no updating of this equipment is
> evident.
>
> At the distillery, the vat containing the harvested
> leaf is positioned Underneath a removable flat lid
> which can be lifted completely clear of the mobile vat
> for ease in loading and unloading the leaf material.
>
> Three evenly-spaced pipes, running longitudinally
> along the floor of the vat, allow steam to be fed
> through a flexible steam line at the bottom of the
> vat. The steam line is fed by a spent-leaf fired
> external boiler. The lid is lowered on to the vat and
> tightly secured using locking clamps, and steam is
> injected. One charge consists of approximately 8
> tonnes of green, uncompressed leaves. Distillation
> begins when the vat is full of leaves and the steam
> then passes through the charge and the oil is
> vaporised. The vat has a drain at the bottom which
> allows for the removal of the residual black liquor
> which consists mainly of tannins.
>
> There are three outlets for the vapour and these are
> connected to one central duct in the centre of the
> lid, allowing for the discharge of the oil/water
> vapours during distillation. The condenser consists of
> a length of pipe running from the vat to a pond. The
> condensate is cooled and the condensed liquid flows
> into the oil collection vessel.
>
> The oil collection vessel is the device for collecting
> the condensed distillate and allows the separation of
> the oil from the water. This consists of an open drum
> partly embedded in the ground. Since the oil is
> largely insoluble in water, it separates and is
> scooped off the surface. The distillation process
> Usually takes 3-4 hours and a typical distillery can
> distill three vat loads per day. The oil is then put
> into 44-gallon drums and sold in crude form for
> approximately US$3 per kilo (Paul Foreman, pers.
> comm., 1994). No further processing of the oil is
> undertaken on site.
>
> Further refining of the oil is done in Melbourne. This
> is done by rectification. Rectification is a more
> controlled distillation process which is used either
> to upgrade the oil or to isolate the major components
> of the oil. The chemicals are then used as precursors
> for chemical reactions or may be used as discrete
> aroma chemicals. For cineole-rich eucalyptus oil,
> rectification is employed to increase its market
> acceptance. Cineole can also be isolated by
> rectification and this is more expensive than basic
> oil and it is mainly used in high quality products
> (Boland et al., 1991).
