i use oxyclean and its a true charmer! best thing ive tryed. ive washed alot of SS ponies and never had issues with water damage or flocking loss, you can use a old tooth brush, just be very gental and dont scrub, dip her in the oxyclean, let her sit for a min' and gently go over the the stain with the brush for best results. hope that helps! good luck and congrats on the new SS ^_^
