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.

If Coke doesn't work try BT200. Are you doing Crime Scene Clean Up now?

I would like to use something that's readily available since we'll be working on it Monday.
No crime scene cleanup - someone slipped, fell and busted their head open and bled on a sidewalk at a strip center.

Oxygen Bleach?
 
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!

Craig, I think he was referring to Sodium Hypochlorite (bleach)
But since you've had luck with hydroxide what exactly is full strength? We use beads so its made up onsite as needed.
 
No I think he meant Sodium Hydroxide - caustic soda - and I of course cannot read - never mind.. carry on LOL :)

Sounds cool to me I'm proud to to be BDA certified!

We need some shirts that look like they have bleach spots on them but are bleach resistant.
