Depending on stain on natural fabrics such as the brown cottons or mohair, if you can find some Naptha, or dry cleaning fluid, blot with that on a hidden test area 1st. Water based cleaners may leave migrating ring stains if not done properly. If the stain is a lighter color than the surround area, and evidence it has been removed before, one can try coffee or a teabag to gently blot the area very slightly to start. Don't saturate the area, just slight blots to start. The lighter Bedford is the most challenging and may need a professional to do.
