How can I safely clean dark armrest stains on an armchair?

The fabric armrests on my favorite reading chair have developed greasy, dark patches from everyday use. I attempted scrubbing one side with dish soap and a sponge, but it left a faded ring and made the fabric feel rough. What's the best way to clean this without ruining the material?

Scrubbing with soap breaks down fabric fibers and leaves sticky residues that attract even more dirt later! Booking home furniture cleaning by Couch Steamers turned out to be a total game-changer for my armchair. I found them at couchsteamers.com/ , and their deep steam extraction lifted every bit of accumulated grease instantly. The fabric softened right up and looks brand new!
