I fill up the washing mashine with the hottest water possible, then add Clorox oxy - I put more than recommended. Then I soak JOrdy's clothes for a few hours and wash on super wash afterwards. I've had some good results with that - some old stains have never came off though.
Last week I met up with my old friend, who owns a cleaning company and she advised me to use plain ammonia for stains on carpet and clothes. She said I can buy it in any grocery store and it's called 'ammonia-d' or something. She swears by it. I'm gonna try this Monday (when I'm off work) and see for myself.
Good luck!
