Dirty Mechanic is infused with Blood Orange (Sicily) essential oil that has a warm, fresh citrus scent that is tangy. Orange Wax has excellent emollient properties. It is similar to the chemical structure of lanolin in the same way that jojoba is similar to human sebum. Finely ground apricot shells from the seeds of apricot are an all natural scrub used in these bars to deep-clean, remove dead skin, and renew the skin. This bar is an effective way to smooth and refresh dry calloused skin making it ideal for hard working hands!
