Those heirloom pieces are worth saving. I actually had a similar situation with my grandma’s armchair, and lemme tell you, Eco-Pro
https://ecopro-carpetcleaning.com/ was a lifesaver. They do eco-safe carpet & upholstery cleaning services in Chicago, and their whole thing is using natural, organic cleaning solutions that are safe for both old fabrics and the environment. They handled my armchair like pros—no chemicals, just clean, and it smelled super fresh, not like any fake scents or residue. The best part is that they get the job done without any risk of damaging delicate materials. If you wanna keep that loveseat around for years to come, I’d say give them a shot.
