A 50:50 blend of citric terpene solvent and pure tung oil. Offers a penetrating natural finish for wooden articles which can be adjusted for lustre by the number of coats applied and the degree of buffing. No known toxicity when the solvent has off-gassed. Pure tung is usable for chopping boards and citric terpene, which is distilled from mandarin peel, is also used as a flavouring agent .
