Help! I need a stain remover that can take blood off a paint wall.

1. Cold water

Hot water sets the protein. Use cold on it while it's still fresh.

As to removing the trace DNA evidence (and there's always trace evidence), I'm afraid I can't help you with that. Luminol tells all.

3. It was dry by the time i saw it

[KamaAina]

2. Ask the White House

They must go through gallons and gallons of the stuff.

4. You'd better tear out the drywall and replace it.

Maybe the floor, too. It's really hard to get rid of trace evidence. Luminol picks up everything. And be sure the neighbors don't find out about your remodeling project; they always tell.

5. Confess your transgression

Else you will see blood on that wall even though it has been fully cleansed.

:yoiks:

6. I leaned against the wall an scraped off a scab. Later I look up an there's blood there

7. If it's a high-gloss wall

A cotton ball dipped in rubbing alcohol will do it (test it on an inconspicuous place first to see if it damages the paint).

18. It also helps if you compulsively rub your hands and say "Out, damned spot!"

8. TSP is a good wall washing solution...

I got it at Lowes when I was getting ready to paint and needed to wash my walls down first.

If you've got stuff originally on the walls that 'bleeds through' (and it doesn't necessarily have to be blood), just something that your paint won't cover, try KILZ or ZEREX.

Had to use that to cover the designs drawn on the wall with Sharpies in my basement apartment. Three coats of paint and they were still surfacing...:grr:

14. TSP is toxic as hell.

And should only be used in a well ventilated area, and only handled with rubber gloves. I'd prefer to live with the bloodstains myself.

15. Actually, TSP isn't terribly toxic. But it is rather corrosive: one really

wants NOT to breath the dust or get any of the stuff in your eyes.

It's not volatile, so ventilation may not make much difference. If making enough dust to inhale, then it's corrosive enough one might want respiratory protection, but the small household packages sold typically contain granules and prudent handling should suffice. Your suggestion to use rubber gloves isn't a bad idea, but a bit on the skin promptly washed off should be okay.

21. A relative once used that stuff

Without gloves, and wound up with second-degree chemical burns on his hands: for weeks he looked like a refugee from a Late Night horror movie. It impressed the hell out of me as a child, but I suspect product labeling has gotten more sophisticated since then.

After all, the cardboard sun screen that covers my car's windshield when parked is clearly labeled "Do not drive with this in place". So I'm sure that now somewhere on the can of TSP it says something to the effect of "Wash this off immediately, unless you WANT to look like one of Dr. Frankenstein's less successful experiments".

22. I don't know exactly what he was doing. I never had problems with it.

I had a short-term job once cleaning up some rental units, which the tenants left filthy.

We filled the kitchen sinks with scalding water, dumped in a box of TSP, threw the stove-hardware into the sinks, and let the stuff work. IIRC, the sinks were too deep for effective rubber-glove protection: so when I wanted to drain them, I probably just shoved my hands into the ugly water, opened the drains, and then rinsed my arms thoroughly, and I'm pretty sure it took several days of such treatment to clean the parts. We probably treated the floors the same way: mopped with scaldingly hot water with TSP

I remember we went through many boxes of TSP, cleaning those places, and if I'd had any adverse reaction I'd absolutely remember it

Actual duration of contact before washing the skin may matter. Concentration and temperature of the TSP solution may be important, too: I certainly didn't jam my hands down into the nearly boiling liquid before it reacted with the grease

Of course, this was thoroughly irresponsible behavior in retrospect: there was probably a long algae plume leaving the sewage plant due to the phosphate we added to the sewer system

9. You have a wall made of paint?

10. It's made from paint balls.

It takes a while, but the results are unique.

11. At some point you won't be able to get it off

Let's say you accidentally had a freeper over for dinner. Obviously you can't kick him out in the street (maybe your wife likes his wife?) but you can have a LOT of fun with him.

So you've got this freeper here, and you start telling him all about how Prescott Bush funded the Nazis, or how Dubya let the Bin Laden family fly out of the US post-9/11, or how the White House all started taking Cipro on 9/11 even though the Cipro package insert says nothing whatsoever about airplanes. You KNOW his head's gonna explode, and by the time you get the gray chunks off the wall, have the cops come by to pick up the body (they call freeper head explosions "natural causes" so don't worry about it much), and so on and so forth, the blood on the wall will have soaked in and congealed and you'll never get it all out.

This is why Zinsser makes B * I * N pigmented shellac primer. It seals in freeper blood, cigarette stench, sap on wood, just anything. Great stuff. Put on a coat of B * I * N, let it sit a couple hours to cure, and paint over it.

12. Hydrogen peroxide removes blood.

It's cheap, too.

[struggle4progress]

17. Perhaps any other bleaching agent would work as well:

household bleach

or the sodium percarbonate / sodium carbonate cleaning agents

or a paste made from a laundry color-safe bleach

20. that's what i was going to say

13. No idea, but if you need a bone saw, I'm the guy
