Hang on, the original colour of that sofa is red is it not? i.e. that red patch you see is the original colour, not a splash of wine.
The red on the scatter cushion is red wine from the looks of it.
I've wet cleaned a few like these in the past and come up great.
I actually have a picture of a green one I cleaned that I'm going to put on my site. Cleaned it twice now, belongs to a restaurant owner who paid £4500 for it. Couldn't test for viscose and it had no labels. Low psi, lots of dry strokes, air mover and lots of towel wiping. No problems.
Just test a small patch at the back with the cleaning products you are going to use. Dry it with a hair dryer. If it looks like its knackard then walk, other wise 98% of the time it'll be fine. Don't be so feared lol
