We just brought up some furniture from the basement to rearrange our living room. One of our leather chairs had gotten something on it. I wish I could tell you what it was, but I can't. Our normal
leather cleaner didn't take it off so we tried a new recipe. We mixed 1 cup white vinegar and 2 tablespoons of olive oil and the stains and dirt wiped right off using a microfiber cloth. Be sure to test in an inconspicuous area first.
