I was given some wonderful old chairs by my grandfather, they are high quality but sadly they are heavily soiled everywhere. We have been using slipcovers but I’m sick of them bunching up and I always have to fix them anytime someone has sat in them. How can I clean these chairs – they don’t have to turn out perfect but less grungy looking would be perfect! I live in a very rural area so we cannot take them to be cleaned. How can I clean them at home? Is there a product that will break up the oil and dirt?
