I bought these 2 ivory chairs years ago and I love the fabric, but couldn’t get the stains out.  I found an excellent solution in Annie Sloan’s chalk paint.  Simply paint the fabric and finish with her wonderful wax. This makes the fabric wipeable and feels sort of like leather. Love it. I highly recommend her brushes, too.  For deeper weave fabrics you will need more paint as the fabric soaks it up. I chose the color “French Linen” for these chairs in the master bedroom.
