Fabric, vinyl, leather , shade, ultra suede, silk, cotton, ?????
I'm not sure if they're leather or cloth but I wrote articles about cleaning both kinds of couches that might help you -
Use Soapy water and a sponge or Baby Wipes etc. If colour has come out use Rienevation shoe polish for white leather. Good luck. Keep polished to prevent.
I use an upholstery attachment on my steam cleaner.
