Agreed, once the bleach has had time to 'set' you're pretty-much stuck with the consequences. You could try re-dying the carpet however here's another who agrees: replace that piece of carpet with a piece that was underneath furniture; you could switch the pieces; most people won't see a 'bad dye job' that's underneath furniture - smile. I've had this problem with carpet and clothing. My attempts at restoring color have yet been satisfactory however I'll keep on trying until I'm happy with the results.
Next time you're cleaning w/bleach near carpet, be sure to carry white vinegar, both mixed to the same dilution. If you quickly douse the area w/vinegar; this will neutralize the bleach. Then blot everything w/a thick towel, rags or wad of paper towels. When i had the vinegar handy, the walls were not damaged; when i had to go get some, the stain was removed but looking at the wall from an angle i could see a slight color change.
Good luck with your efforts. Keep us posted :o)
Agreed that you can't "undo" what's been done.
If you do decide to replace the area w/a piece of carpet, say, from inside a hall closet, be sure to cut both the old and new pieces as a wavey circle shape of sorts. This will help "hide" the lines of the cut once replaced. If you cut it as a square shape they will be easily seen and always shifting, or the corners curling up. (I worked for a carpet retailer/wholesaler/installer/freighter for several years.)
It would actually be best to hire a reputable, professional carpet installer to do this job.
CUT IT OUT AND GLUE A PIECE FROM AN INCONSPICUOUS SPOT IN TO THAT PLACE. LIKE FROM A CLOSET ETC.
I agree, there is no remedy, did this myself. Used the bleach drops in the humidifier when I ran out of treatment liquid. NOT THE SAME. Wish it were.
The area rug sounds like a good plan if you don't want to replace the whole carpet. Clorox removes color, it doesn't lay a stain over it like punch does.
Call a carpet cleaning company. Some of them offer a dye service for problems like this. I've never had to do this, so I can't say if it works or not, how well they can match the color of your carpet, or how long it lasts.
You might be able to cover the spots with an area rug.
Actually that is not a stain, that is a bleached out spot. there is no remedy.
