Here are some methods for you.
Hydrogen peroxide will work but test first for color safety. You can blot it with a cotton cloth or microfiber.
hot water and dreft laundry detergent get out anything - even strips wallpaper, removes paint ,etc easily
Here are a few ideas from Coit to remove blood stains from carpet. Wishing you the best.
3% hydrogen peroxide will not pull carpet color from any wall to wall carpet, unless it is wool and that’s extremely unlikely. So try that.
I would not use hot water, as carpet is assembled with heat and hot melt glues, as in “why Stanley Steamer stretches out your carpet” because the heat breaks down the original assembly methods.
Nature’s Miracle is live enzymes that eat vomit, feces, urine & blood. Being live enzymes they cannot survive in an environment that’s been contaminated with harsh cleaning chemicals and so, if you’d like to buy this versatile product, do it first, before you try something else
I would try either Folex, you can get it in Home Depot or Lowes, or KrudKutter for carpets. Peroxide will clean blood but may change the color of the carpets.
Here is a good source of information:
Hi ! First I would use an enzyme cleaner that you can buy in any let supply store . This "eats" natural substances like urine , feces , blood or vomit . Then I would use Folex carpet cleaner , it is hands down the best !!!!! I found it at home depot for about $6 . Good luck !!!
Hi Mary: Pour hydrogen peroxide on it. It will bubble up, and then use a white wash cloth to blot, not scrub, the stain. Do this until the stain is gone. Near the end, when the stain is faint, you can scrub. This should do it. Good luck
