In brief
Blood, vomit and other bodily fluids are everyday hazards in healthcare, dentistry, physio and vet work, and most stains can be removed from scrubs completely if treated correctly. This guide explains how to remove blood and fluid stains from scrubs with cold water and the right products, how to wash scrubs afterwards, and which habits keep stains from setting in for good.
- Cold water is the key to removing stains from scrubs: hot water sets protein-based stains permanently.
- Blood and bodily fluids respond best when treated within minutes, not at the end of a shift.
- An enzyme-based stain remover, diluted hydrogen peroxide and a mild detergent cover most situations.
- Check a treated stain is fully gone before it goes anywhere near a tumble dryer.

Stains on scrubs are an everyday reality in healthcare, dentistry, physio and vet work. Blood, vomit, saliva and other bodily fluids are bound to end up on a uniform at some point during a shift. The reassuring part is that most of these stains can be removed completely, provided they are treated correctly and reasonably quickly. This guide covers how to remove blood and fluid stains from scrubs properly, which products are worth keeping on hand, and the habits that make stains easier to manage over time.
Why You Should Remove Stains from Scrubs as Soon as Possible
Blood, saliva, vomit and most bodily fluids are protein-based. While fresh, the proteins sit on top of the fabric rather than binding to it, which is why cold water works so well early on. Once a stain dries, or goes through a hot wash before it has been treated, the proteins bind to the fibres and effectively set in place. At that point, no stain remover will fully shift it.
The most important factor in removing stains from scrubs is timing rather than any particular product. A quick cold rinse during a break is more effective than a strong stain remover applied several hours later at home.
Before treating any stain involving blood or bodily fluids, follow your employer's infection control policy on handling and laundering contaminated scrubs. Wear gloves when treating a stain at work, and wash your hands afterwards.
How to Remove Blood Stains from Scrubs
Blood has a reputation for being difficult to remove, but it responds well to cold water when treated early.
- Rinse under cold running water, working from the back of the fabric to push the blood out rather than further into the weave.
- Avoid hot water for stain removal. It sets protein stains almost instantly and turns a treatable mark into a permanent one. Use cold water to treat the stain itself, then wash the scrubs at the highest temperature the care label and your employer's policy allow.
- Soak fresh stains for 15 to 30 minutes in cold water with a small amount of mild detergent, which often removes most of the colour before any stain remover is needed.
- Give dried blood a longer soak, up to a few hours, changing the water once it discolours, before applying a stain remover.
- Blot rather than scrub. Vigorous rubbing can push blood deeper into the fabric and gradually wear down the surface, particularly on stretch or performance scrub fabrics.
- Finish with a targeted treatment. Once most of the stain has lifted, an enzyme-based stain remover or a small amount of diluted hydrogen peroxide applied directly to the mark usually finishes the job. Leave it for the time stated on the product, then rinse and wash as normal.
- Patch test hydrogen peroxide first, particularly on darker or printed scrubs, as it can lighten colour.
How to Remove Bodily Fluid Stains from Scrubs
Vomit, urine and other bodily fluids follow the same principle as blood: cold water first, protein-specific products second, though the process differs slightly in practice.
- Remove any solid matter first, using a spoon or the edge of a cloth rather than your hand.
- Rinse from the reverse side of the fabric under cold running water, flushing the stain out rather than through it.
- Pre-soak in cold water with an enzyme detergent for at least 15 minutes. Enzyme detergents are formulated specifically to break down the proteins found in bodily fluids and generally outperform a standard wash on its own.
- Deal with odour separately. It can linger even once the stain itself is gone, so a short soak in cold water with a small amount of white vinegar, or a dedicated odour-neutralising laundry additive, usually resolves this before the item goes into the wash.
- Treat exposed skin first. If a stain has soaked through to an undershirt or skin, follow your workplace's exposure protocol before dealing with the garment.
The Best Products to Remove Stains from Scrubs
A small, consistent set of products handles most stains encountered on shift.
Enzyme-based stain remover
The most useful item to keep on hand. It targets protein stains specifically, rather than general dirt, and works on both blood and bodily fluids.
Diluted hydrogen peroxide
A useful backup for blood, gentler than bleach. Always patch test first and use sparingly on coloured fabric.
Mild, colour-safe detergent
Matters more than it might seem. Harsh detergents and fabric softeners can gradually strip the moisture-wicking finish on performance scrub fabrics.
Cold water
Free, always available, and doing most of the actual work behind every method above.
Chlorine bleach is best reserved for plain white scrubs. On coloured or patterned fabric, it fades dye unevenly and weakens the fibres with repeated use. For stretch or performance fabrics, such as our Koi Lite collection, it is worth checking the care label before using anything stronger than a standard detergent, as some finishes are more sensitive to bleach and high heat than standard cotton-blend scrubs.
How to Wash Scrubs After Treating a Stain
Treating the stain is only part of the process. How the garment is washed afterwards determines whether the stain actually stays out.
Check the treated area in natural light once the wash cycle finishes, before it goes anywhere near a dryer. If any trace remains, treat it again and rewash rather than relying on the dryer, since heat will set any residual staining permanently. Follow the wash temperature on the care label, particularly for stretch or moisture-wicking fabrics, which can lose shape or performance if washed hotter than recommended. Where possible, wash contaminated scrubs separately from the rest of your laundry, in line with your workplace's infection control guidance.
Mistakes to Avoid When Removing Stains from Scrubs
A small number of habits account for most stains that never fully come out.
| Mistake | Why it matters |
|---|---|
| Using hot water on a fresh stain | The most common reason a treatable stain becomes permanent. |
| Scrubbing instead of blotting | Pushes the stain deeper and can damage the fabric surface. |
| Tumble drying before checking | Confirm the stain has actually gone, since heat sets any trace that remains. |
| Overusing bleach on coloured scrubs | Causes patchy fading over time. |
| Letting a stain sit for a full shift | The longer it dries in, the harder it is to remove later. |
| Skipping the care label | Performance and stretch fabrics do not always behave like standard cotton scrubs. |
How to Keep Your Scrubs Stain-Free and Looking New
Stains are difficult to avoid entirely in this line of work, but a few habits make them easier to manage.
Keeping a small stain kit in a bag or locker helps considerably. A travel-size enzyme spray and a couple of wipes cover most situations until a proper rinse is possible. Rotating between a few sets of scrubs, rather than relying on one or two, also helps colour and fabric hold up better over time, since no single set is washed excessively often. Fabric choice plays a role too: scrubs that are genuinely easy to wash and hold their colour well, such as our Koi Basics or Koi Cureology, tend to show less wear from repeated stain treatment than heavier, less forgiving fabrics.
Storage matters as well. Packing scrubs away damp can set in odours and make the next stain harder to remove, so it is worth allowing them to dry properly first.
FAQ - How to Remove Stains From Scubrs
What's the fastest way to remove blood stains from scrubs?
Rinse the stain under cold running water as soon as possible, then soak in cold water with a mild detergent before applying an enzyme-based stain remover. Treating blood while it is still fresh is far more effective than attempting to remove it once it has dried.
Can you use hot water to remove stains from scrubs?
No. Hot water sets protein-based stains, such as blood, vomit and other bodily fluids, into the fabric, making them much harder to remove or impossible to shift completely. Always use cold water for the initial rinse and soak.
Will hydrogen peroxide damage coloured scrubs?
It can lighten colour on dyed or printed fabric, so it should always be patch tested on an inside seam first. On coloured scrubs, an enzyme-based stain remover is usually the safer first choice, with diluted hydrogen peroxide kept in reserve for tougher stains once tested.
How do you remove old, dried stains from scrubs?
Soak the garment in cold water for several hours, changing the water once it discolours, then apply an enzyme-based stain remover directly to the mark. Dried stains take longer to shift and may require more than one treatment cycle, but they can often still be removed provided they have not been through a hot wash or dryer.
