Could you recommend a good fabric cleaner that you have used that has worked well for you?

What’s the fabric? (Next time buy food-colored fabric.) Turn the chairs upside down and see whether the seats can be removed easily. Then you can buy other fabric and staple on.

I have no recommendations for actual fabric cleaners. They are all nasty and have fumes you don’t want to breathe.

We just spilled wine on a white chair. I had had other experience with other staining type foods—and here is the amazing thing to use—It works!!! Hydrogen Peroxide. If it’s a really bad stain, mix it with soap and scrub. The red wine was gone after an overnight soak. A miracle, I tell you, a miracle!
