How to dry and clean a couch?

I found this really cute floral couch near my dumpsters that I would like to try and save and put it in my room. I was inspecting it and I found no bugs or stains at all. The only bad thing is, it's been raining for the past few days and the couch is quite wet. I put a tarp over it last night but it hardly worked. Now, it is safely under an overhanging, so no more water will get to it. But it is very wet and moist. I would like to know if anyone has any drying and/or cleaning tips, advice, or products I should use. I have a lot of time to try and salvage this couch, and to me it's worth it. I love would any tips I could get. Thank you!
