How to Remove Blood Stain
Cold water only is the first rule for blood stains. Hot water sets blood protein into the fibers and makes removal much harder. In Tucson, hot tap water reaches high temperatures fast, which raises this risk.

How to Remove a Blood Stain from Carpet, Fabric, or Hard Surfaces
Blood stains set fast when they dry or meet heat. The protein in blood bonds tightly to fabric fibers when warm. Always use cold water. On carpet, hydrogen peroxide at 3 percent works well. On fabric, a salt paste draws blood out before it dries. In Tucson, even the cold tap can run warm in summer, so fill a glass with ice water for stain treatment.
Blood on Fabric
Rinse under cold running water first. Make a paste of salt and cold water and press it into the stain. Let it sit for 5 minutes. Rinse with cold water and repeat. Finish with dish soap if needed.
Dried Blood Stains
Re-wet with cold water first and let the stain soak for a few minutes. Apply hydrogen peroxide to carpet or salt paste to fabric. Dried stains need more time and more passes to lift.

Why Hot Water Makes Blood Stains Worse
Blood contains proteins that coagulate when heated. Hot water causes these proteins to bond tightly to fabric fibers, making them nearly impossible to lift out. This is the same process that happens when you cook meat. Cold water keeps the proteins loose so blotting can remove them.
Tucson hot-water tap temperatures can run very high in summer months. Always run cold water or use ice water when treating a blood stain. Test hydrogen peroxide on a small hidden spot first since it can lighten some carpet and fabric colors.
How to Remove Blood Stain FAQ
Does hydrogen peroxide bleach carpet?
It can lighten some carpet colors. Test it on a hidden area first. Use 3 percent hydrogen peroxide, not a stronger concentration. Rinse the area well after treatment.
Can I use warm water if I cannot get cold water fast enough?
No. Even warm water can begin to set blood protein. Use cold water only. Fill a cup with cold tap water and a few ice cubes if needed.
