Just had a champion cloth put on my table about 3 weeks ago. Came home to my daughter and her boyfriend playing on it. After they finished I went out to play and there's a finger sized dark spot on the cloth. She doesn't know what it is, I tried a light solution of vinegar and water lightened it some. Brushed it on let it dry... seemed to fluff the felt more than get rid of the stain. Any suggestions on how to clean it? Sorry if this has been asked before, I did several search's but didn't turn anything up. Thanks,
Brad
