How to Wash Surgical Scrubs Without Ruining Them

A set of surgical scrubs goes through the machine two or three times a week, often more. Over a year that adds up to more than a hundred washes. This is where everything is decided: two colleagues who buy the same scrubs on the same day can end up, twelve months later, with one crisp set and one grey, misshapen, pilled one. The difference almost never comes down to what they paid. It comes down to how they washed them.

This guide covers everything that matters about caring for modern medical scrubs: wash temperature, blood and iodine stains, drying, ironing, and the point at which a set genuinely needs replacing.

What temperature should you wash scrubs at?

Short answer: 30-40 °C, with a detergent containing active oxygen. Not 60 °C out of habit, and never 90 °C.

That surprises people, because the 60 °C rule has been repeated for decades. It dates from an era when hospital uniforms were heavy white cotton. Modern scrubs are cut from a technical stretch fabric — that is what gives you room in the shoulders, the freedom to crouch, and a sharp silhouette after a twelve-hour shift. The elastic fibres that make this possible cannot handle boiling water.

UK NHS guidance for healthcare employers is explicit: a 30 °C wash with a proper detergent already eliminates MRSA and the vast majority of bacteria. The US CDC adds the decisive caveat — low-temperature cycles work provided they rely on an oxygen-activated agent. Heat alone is not what disinfects. It is the combination of detergent, active oxygen and enough mechanical action.

• 30 °C — routine care, lightly worn.
• 40 °C + active oxygen — the benchmark setting after a real shift in theatre.
• 60 °C — only where the care label allows it, knowing the fabric will age faster.

Why 60 °C damages modern scrubs

Heat is the number one enemy of modern stretch medical scrubs. From 60 °C upward, elastic fibres contract and then break down progressively. In practice: a neckline that gapes, a waistband that stops springing back, knees that bag, colour that shifts within months.

The fabric used in a quality set of surgical scrubs is chosen precisely for its resistance to creasing, its colour stability wash after wash, and how soft it stays against skin . Those properties are real and measurable, but they only hold as long as you do not cook the fabric. A single 90 °C cycle can set a permanent crease or .

Removing blood, iodine and ink

One rule outranks all the others: cold water first. Blood, sweat and most body fluids are protein stains. Heat coagulates them and locks them into the fibre permanently.

• Blood — rinse immediately under cold water, never hot. Work in a little soap gently, then wash as usual.
• Iodine — flush with plenty of cold water before the stain dries. Dried iodine is far harder to lift.
• Ink — dab with surgical spirit on a clean cloth, working from the edge inward so you do not spread it.
• Grease — technical fibres hold on to oils. A drop of washing-up liquid on the mark before the wash solves it.

Absolute rule: never iron a garment while a stain is still visible. The heat makes it permanent.

Fabric softener: skip it entirely

This is the most common and most expensive mistake. Softener leaves an oily film across the fibres. On scrubs this triggers three problems in sequence: the fabric breathes less, it wicks sweat less effectively, and it traps odour instead of releasing it. The same film neutralises any antibacterial finish on the textile. A uniform that smells after a few hours has almost always been washed with softener.

The same logic applies to chlorine bleach: it attacks elastane and strips colour in uneven patches. On coloured scrubs, use an oxygen-based stain remover instead — it disinfects and lifts marks without touching the dye.

Drying: the mistake that ruins a set

No tumble dryer. This is the one point not to compromise on. Drum heat shrinks the garment, breaks down the stretch and fatigues seams faster than any wash cycle.

These fabrics dry very quickly in open air. Hang the set on a hanger, inside out, in the shade. Direct afternoon sun fades blues and greens within weeks — a real consideration in a North African climate. Dried on a hanger, scrubs recover their shape on their own and usually need no ironing at all.

Ironing: 110 °C maximum, inside out

If you do iron, stay on the lowest setting (110 °C, one dot) and always work on the reverse side. It is also recommended to place a clean, slightly damp cloth (a pressing cloth) between the iron and the garment to protect the fibers and prevent heat marks. An iron that is too hot glazes the fabric: the area turns shiny and the damage cannot be undone. Never run the iron directly over embroidery or printed logos.

The habits that age scrubs prematurely

• Overfilling the drum — laundry needs room to move to be washed and rinsed properly.
• Eyeballing the detergent dose — overdosing leaves residue that stiffens fabric and holds odour.
• Leaving a damp set at the bottom of a bag until the next day.
• Mixing work clothes with the family laundry, especially children's clothes.
• Folding scrubs away while still slightly damp: in a humid climate they smell musty by morning.

One overlooked detail: clean your washing machine. A dirty drum recontaminates clean laundry. An empty 90 °C cycle once a month settles it.

What about scrub caps and clogs?

Cotton scrub caps handle 40-60 °C; if yours are printed, wash them inside out at 30 °C. Clogs clean up with a sponge and warm soapy water — never in the dishwasher or under very hot water, both of which deform EVA foam permanently.

Frequently asked questions

Can you wash scrubs at 60 °C?

Yes where the label permits, but it is not necessary day to day and the fabric will wear out faster. A 30°C wash with an active-oxygen detergent gives an equivalent hygienic result for routine use.

How do you get rid of a smell that will not go away?

Soak the garment for 30 minutes in lukewarm water with two tablespoons of baking soda, then wash it normally without fabric softener. Persistent odors almost always come from greasy residues trapped in the fabric, not from a lack of washing..

Can scrubs go in with the household laundry?

No. Keep them separate, carry them in a dedicated bag, and change on site where you can.

Do scrubs shrink in the wash?

A well-chosen technical fabric barely shrinks at 30-40 °C. Shrinkage almost always traces back to a tumble dryer or a wash that was too hot.

In short

40 °C, active oxygen, no softener, no tumble dryer, hang-dry in the shade, cool iron on the reverse. Five habits that turn a disposable-feeling uniform into one that survives two years of shifts.

Our surgical scrubs are cut from a technical stretch fabric selected for exactly these constraints: low-temperature washing, fast drying, stable colour and almost no ironing. To preserve your scrub set even longer, hand washing remains the best option whenever possible. It reduces mechanical friction and helps extend the fabric’s lifespan. Delivered anywhere in Tunisia.
