stubborn stain

I am really struggling with this stubborn stain on my favorite couch, and it's driving me crazy! A few weeks ago, my friend spilled some red wine during movie night, and ever since, I've been trying everything to remove this annoying stubborn stain. I’ve tried the usual baking soda and vinegar mix, which is supposed to be safe for fabric, but it seemed to only lighten the stubborn stain a tiny bit. My mom suggested a commercial cleaner, but I’m nervous about using something harsh on the fabric. The worst part is that every time I see that stubborn stain, it annoys me more and more. Sometimes, I feel like I should just give up and get a new couch, but I’vehad this one for years! Anyway, I noticed a few DIY methods online that involve using dish soap and club soda mixed together, but has anyone actually had success with those? Should I maybe consider calling in a professional cleaner? I really don’t wanna make the stubborn stain worse. Left untreated, I worry it will just become a permanent eyesore. Any tips or advice would be super appreciated!!! Thanks in advance!
