use bleach on carpet to get stain out?

[Erin K.]

We have a duplex we are rehabbing. Living room has an offwhite berber carpet that is in like new condition and looks very nice with the exception of 2 places where there are stains. One is a large circle. Professional cleaning dulled it, but it is still the first thing you notice when you walk into the room. So I got this crazy idea and wondered what, if anything, some bleach would do to it.  Any ideas? The room is large and I hate to tear the carpet all out but these 2 spots really bother me. One is about 2 feet in diameter  Just wondered if anyone else has tried this remedy and what results you got. Thanks!
