Recently cleaned 6 dining room chairs. Tag said "polyester fiber".
The homeowner mentioned a prior cleaner had to come back to remove some yellowing. I used Prochem upholstery prespray and flushed with the Saphire tool. Sure enough the day after the cleaning she calls to let me know some yellowing appeared. Went back and found yellowing on several chairs, it was around piping and edges. All of the yellowing came out except for this on the back of one chair.

This was the worst of the yellowing and it didn't come out with regular upholstery prespray. The yellowing seems set in the fabric. I think this is a jacquard? Any thoughts on how to remove the yellowing if possible?
