We have a white Denali SUV, and my four-year-old stepson decided to make it his canvas for drawing. He proceeded to create his large masterpiece all over the passenger side and back with a blue pen. My husband tried clean it and scrubbed and scrubbed with soap and water. I went out with my Purification essential oil blend and a damp rag. I proceeded to clean the entire car in ten minutes. Purification took every bit of it off! Thanks Young Living for your outstanding dedication and commitment to making the best grade essential oils out there.
