Guide by type of soiling to choose the best color for your medical uniform

In clinical and healthcare settings, not all stains are the same: blood, disinfectants, sweat, and food residue have different tones and behave differently on fabric. Choosing the right uniform color can make the difference between maintaining a professional appearance throughout your shift and having to ask for permission to change. Here, I'll explain, stain by stain, which colors work best and why.

1. Blood stains — which colors disguise best

Problem: Blood has reddish tones that, depending on the base color of the uniform, may stand out a lot or a little.
Best option: navy blue and dark green.
Why: Dark and cool tones mask reddish tones; the contrast is less and the stain is less evident.
Practical notes: subtle prints or textured fabrics also help to camouflage small splashes. Avoid whites and pastels.

2. Stains from disinfectants (povidone-iodine, dyes, coloring solutions)

Problem: Products such as povidone-iodine (brown/reddish color) and some disinfectants or medical dyes can stain the fabric.
Best option: navy blue, dark gray or black.
Why: Deep or highly pigmented colors reduce contrast compared to brown or yellowish tints.
Caution: Some products leave permanent marks on light-colored fabrics, so in areas where they are frequently used (operating room, dressings) dark colors or specific uniforms are recommended.

3. Stains from alcohol, clear solutions, or chlorhexidine

Problem: many stains are not color, but residue that alters texture or leaves shine; in some cases they cause lightening.
Best option: medium gray or navy blue.
Why: Medium tones better conceal differences in brightness and minor discoloration; navy blue also better disguises wear and tear.
Tip: If the product bleaches the fiber, the dark color visually softens the damage.

4. Sweat stains — colors that work best

Problem: Moisture and sweat stains are noticeable depending on the color and composition of the fabric.
Best option: black, charcoal gray or navy blue.
Why: Dark colors reduce the appearance of dampness; medium gray can disguise older sweat stains.
Warning: In technical fabrics that change color when wet (some polyester), it is best to test beforehand, as some colors appear much more damp.

5. Food and beverage stains (coffee, sauces, fruit)

Problem: brown, reddish, or yellowish pigments that often leave halos.
Best option: navy blue, dark gray, discreet prints.
Why: Dark colors reduce the contrast of food pigments; small patterns help to visually “break up” the stain.
Suggestion: In services with a high risk of splashes (nutrition, hospital kitchen) it is advisable to use fabric with anti-stain treatment and dark colors.

6. Other practical considerations (materials + maintenance)

  • **There is no “miracle color”**: color helps, but the fabric composition (polyester vs. cotton), stain-resistant finishes, and industrial treatment make a much bigger difference.
  • Deep dark vs. absolute black: black hides very well, but in formal environments or with dress codes it can be excessive; navy blue is usually the most versatile option.
  • Prints and textures: discreet patterns or textured fabrics hide small stains better than completely uniform plain fabrics.
  • Washing and drying: a good routine prevents stains from setting. Avoid harsh drying that sets pigments.
  • Institutional code: always confirm with your center if there are color restrictions before deciding.

7. Quick recommendation according to service type

  • Emergency room / urgent care / operating room (blood & disinfectants ) → navy blue or dark green.
  • Patient care (sweat & close contact) → navy blue, dark gray.
  • Nutrition / healthy cooking (food) → navy blue, discreet prints, stain-resistant fabrics.
  • Pediatrics (visual attachment, do not always prioritize dark) → light blue with protective apron or combine with tones that allow for quick cleaning.

To conceal stains according to their type, the rule of thumb is: dark colors (especially navy blue, dark green, and dark gray) work best against blood, disinfectants, sweat, and food. Complement your color choice with treated fabrics, subtle prints, and proper washing practices to maximize durability and maintain a professional appearance.

¿Los scrubs con protección UV son necesarios?
Are UV-protective scrubs necessary?
In recent years, some manufacturers have started promoting scrubs with "UV protection" as if they were an essential advancement. It sounds good, but... do you really need them for your daily work in the medical field? Do healthcare professionals really need scrubs with UV protection? Most medical staff work in indoor spaces: hospitals, consulting rooms, laboratories, radiology, procedure areas, private clinics. In these environments, exposure to UV rays is minimal and does not represent a real risk. In addition, the fabric of medical uniforms usually has a high density and colors that already act as a natural barrier. Simple conclusion: For the vast majority of doctors, nurses, technicians, physiotherapists, and administrative staff, it is not necessary to buy scrubs with UV protection , especially if they are more expensive. Who could benefit from this feature? Although it is not a general necessity, there are cases in which UV protection does add value: Nursing or physiotherapy staff who make home visits. Professionals who spend time in outdoor areas of the hospital. Community activities, health fairs, outdoor vaccination campaigns. People with very sensitive skin or with a medical recommendation to avoid sun exposure. Personnel from mobile units or brigades working under the sun. In these scenarios, a scrub with a UV filter can help reduce cumulative exposure. Advantages and limitations of UV-protective scrubs Advantages Less sun exposure during outdoor tasks. The fabric may age less when it receives direct sunlight. Limitations In indoor environments, its effect is practically imperceptible. The price is usually higher without providing real benefits in hospital routine. It is a function aimed at a very specific group, not at all healthcare professionals. So, how do you choose the right medical uniform? For most staff, it's best to prioritize: Good breathability Fabric resistant to constant washing Elasticity and comfort A cut that allows unrestricted movement If you occasionally work outdoors, a light jacket or accessories like a hat and sunscreen are usually more practical than buying specialized scrubs. Scrubs with UV protection They are not a requirement for those who work within hospitals and clinics. They're only really useful for those who spend time a long time in the sun or have specific needs. Choose your uniform with your actual work environment in mind, not added features you may not need.

¿Qué hacer si mis scrubs nuevos sueltan pelusa?
What to do if my new scrubs are shedding lint? Guide
When you wear new medical uniforms, the last thing you want to see is lint everywhere : on your shirt, on your lab coat, on the clinic chair... a disaster! But don't worry, this is more common than it seems and there's a solution. Here's a clear and useful guide to understanding why it happens and how to avoid it from the first wash. 1. Why are my new scrubs shedding lint? Lint shedding usually occurs for three reasons: ● Type of fabric Blends with cotton tend to release loose fibers at first, especially if they are new or minimally processed. ● Manufacturing process During cutting and sewing, microfibers remain that are not always removed before packaging. ● Friction during washing When washed with towels, sweatshirts or rough garments, shedding increases. 2. Is this normal? Yes. Many scrubs need between 2 and 5 washes to stabilize. If the lint continues after this time, it may be a problem with the quality of the fabric. 3. What to do to get rid of lint? (Quick solutions) ✔ 1. Wash them by themselves the first few times Avoid mixing them with garments that cause friction. Use a gentle cycle and cold water. ✔ 2. Use a laundry bag It reduces friction and traps loose fibers. ✔ 3. Add white vinegar Half a cup helps seal the fibers and soften the fabric. Don't worry, the smell will go away. ✔ 4. Use a dryer with a lint-catching sheet The dryer helps to remove loose fibers faster. If you don't have any, use drying balls. ✔ 5. Run an adhesive roller over it Remove surface lint quickly after drying. 4. Extra tricks if the lint persists Gently brush the uniform with a clothes brush. Check if the fabric is of low quality: some fabrics shed lint continuously. Avoid washing with towels, terry cloth pajamas, or wool clothing. 5. How to prevent lint in future scrubs ● Choose good quality fabrics, especially polyester-rayon-spandex blends. ● Avoid 100% cotton if your priority is zero lint. ● Always wash with soft clothes and similar colors. Just because your new scrubs shed lint doesn't mean they're defective. It's very common and, with the right care, the problem disappears quickly. A few controlled washes and small adjustments to your routine will keep your medical uniforms looking clean, professional, and lint-free.
