Here is the answer to a question I received recently…
Step one…no sharpies near the fancy couch!
Sharpie marks on the Ethan Allen ouch that’s not good, sharpie and markers are rarely cleaned using a water based cleaner like spot cleaners etc. They are normally cleaned using some kind of solvent, however solvents are harsh and will remove all colors including the stain and or damage many fabrics.
The best solvent for this application (for cleaning fabrics etc) is likely a dry cleaning solvent (which can be purchased at any janitorial supply store). Even so you will want to test an inconspicuous spot first and always tamp or blot the stains with a white cleaning towel no scrubbing allowed. the idea is you want to transfer the stain onto the absorbent cleaning towel with the help of your cleaning agent.
However if the couch is expensive you are likely better off getting a professional carpet/upholstery cleaner. Be sure that they are iicrc certified (www.iicrc.org) they will have a multiple options and lots experience with spot cleaning all types of couches etc.
