Sorry if this is the wrong subsection, not sure where to ask about sofa woes. We bought two John Lewis Arlo sofas in Feb 2018. We don't eat on them or do anything filthy so other than an occasional dust and vacuum they haven't been cleaned.
I noticed one seat was looking a tiny bit grubby so wiped it with a damp cloth - honestly quite gentle, not scrubbing, just water. The colour came off onto the cloth! It has dried to a light patch (see photo).
Can I fix this or do I need a professional? Also, how should I clean it in future if a damp cloth is clearly not the way to go? I'm pretty sure there was nothing on the instructions.
(I'm waiting for a call back from JL furniture dept but they said it will probably be next week).
