Gather before you start
Everything should be within reach so you are not walking around with contaminated gloves.
- Disposable gloves, ideally nitrile; two pairs if you have them
- Paper towels or disposable cloths
- A disinfectant whose label lists bloodborne pathogens or hepatitis B, or a fresh household bleach solution
- A plastic trash bag that can be tied shut
- Eye protection if there is any chance of splashing
- Tongs or a dustpan for any broken glass
The order that actually disinfects
Keep others away
Ask family members to stay out of the room until you are done.
Remove sharp pieces first
Pick up broken glass with tongs or a dustpan, never fingers, and put it in a rigid container.
Absorb, then clean
Blot liquid with paper towels and bag them. Then wash the surface with soap and water. Disinfectants work poorly on surfaces still covered in blood.
Disinfect and wait
Apply the disinfectant and leave it wet for the full contact time on the label, often several minutes. Wiping it off immediately undermines the step.
Bag and wash
Put towels and gloves in the bag, tie it, and wash your hands thoroughly with soap and water.
Common mistakes and why they matter
| Mistake | Why it is a problem | Better choice |
|---|---|---|
| Spraying disinfectant onto a pool of blood | Can splash and the product cannot work through the volume | Absorb first, clean, then disinfect |
| Using a scrub brush on porous grout | Pushes material deeper and spatters | Blot and use disposable cloths; consider professional help for grout |
| Mixing bleach with other cleaners | Can release harmful gases, especially with ammonia or acids | Use one product at a time and ventilate |
| Reusing a sponge or rag | Carries contamination to the next surface | Use disposables and throw them away |
| Skipping the contact time | The disinfectant may not finish its job | Follow the label exactly |
Common questions
Is bleach safe to use on blood?
A freshly mixed household bleach solution is a widely recommended disinfectant for blood on hard surfaces. Follow the product label for dilution, use it with good ventilation, and never mix it with other cleaners.
What about blood on clothing?
Washable fabrics with small amounts of blood can usually be laundered separately in cold water and then hot, wearing gloves to handle them. Heavily soaked items are usually better discarded.
