While re-roofing the house, I got roof tar on my hands, clothes, and on the carpet. I used Thieves Household Cleaner undiluted on my hands, then slightly diluted it in water for the carpet. The tar came off quickly in both cases. My friends, who thought only paint thinner or gasoline would work, were very impressed. Essential Oils are solvents of the safest kind – a far better choice than gasoline or paint thinner.
