How can you remove paint from a leather couch?
These type of cleaner pads are not really safe to use on leather as they are abrasive and can remove the finish or pigment along with the dye transfer.. Dye transfer on leather can be removed using a leather safe cleaner like LTT Maxi Cleaner which was developed for that type of problem. If it cannot be removed with this then the problem is a technical one rather than a cleaning one and should be resolved by a qualified technician.
Use acetone. It'll eat it right out. And probably the couch material as well.
