Leather isn’t necessarily easy to stain, but if you do get one on your leather couch, rest easy because there is a simple solution to removing them. Watermarks can easily be removed with just a wipe with some white vinegar. Always test a spot on the couch that isn’t easily seen first before attempting to remove the stain.
Just dab a little bit of white vinegar on a clean cloth and wipe away the watermarks. Don’t press to hard, just a little pressure is all that is needed. It should just come right up.
If you have a scuff mark on your leather couch, this can be removed with an ordinary pencil eraser. Just the eraser on the end of a pencil is enough to do the trick if the scuff mark is small, but for larger marks, use one of those bigger erasers to get the job done.
