Hi, we have a new leather sofa in our living room. Last week, my kid scribbled on the sofa with a pen. I tried removing the stain with water and dishwashing gel, but it didn’t work. I searched online and found an article regarding the protection of leather sofas [ http://www.surplusfurniture.com/blog/how-to-protect-your-leather-sofa/ ]. It says using a leather cleaner can help remove stains. I don’t have a leather care agent and don’t know if it would work for me. Are there some DIY methods I could try to remove the stain? Please help me with your suggestions.
