If Coke doesn't work try BT200. Are you doing Crime Scene Clean Up now?Anyone know the best way to remove dried blood stains from concrete?
I've done a search but couldn't find anything.
Bleach, degreaser, oxalic acid, Taginator?
Any help would be greatly appreciated.
Thanks.

Sodium precarbinate will work mixed strong,sometimes straight sh will remove it.
We clean up quite a bit of blood from roadrunners killing and eating lizards on customer's driveways.
Like Kiloman we've have great success with Sodium Hydroxide. Spray on full strength, brush with truck brush and low pressure rinse with hot water. They come out 100% on the gray concrete.
Never tried hydrogen peroxide but it makes sense that it should work too. Let us know what you tried and how it came out!
Shane, people want the BDA to become an ORG or more like a club.
