Stain Removal and Correct Washing Guide for Medical Uniforms

Washing and Drying Standards by Fabric Fibre

The medical scrubs worn by healthcare professionals are exposed to the toughest biological fluids and chemical agents all day long, making them the most frequently washed technical textile products. However, every fabric fibre reacts differently to heat, detergent, and mechanical friction. To extend the uniforms' lifespan and keep their colour vibrancy looking like day one, the washing and care instructions suited to the fibre type must be followed exactly.

Cotton medical uniforms are comfortable due to their naturally high air permeability, but are prone to shrinking and fading. Coloured cotton items should be washed at 30-40°C, while white cotton lab coats can go up to 60°C for stubborn stain removal and disinfection. Fabrics containing polyester fibre are known for their stain resistance and quick-drying properties; it's recommended these be cleaned at 40°C without chlorine-based bleach, which damages the weave.

Uniforms with elastane (lycra/spandex) blends offering superior 4-way stretch, like Advanced Flex™, are extremely heat-sensitive. Lycra uniforms must absolutely be washed at 30°C on a delicate wash cycle. Hot water damages elastane's stretchy fibre structure, causing the uniform to sag and permanently lose its elasticity. This type of stretch fabric should not be put in the tumble dryer, and should instead be air-dried by hanging in a shaded area away from direct sunlight.

Science-Based Solution Protocols for Common Medical Stains

Since the chemical composition of stains occurring in hospitals and labs differs, washing at random can set the stain permanently into the fabric. For the correct result, each stain must be treated with a specific reactive agent.

• Blood Stain Removal: Blood stains, a protein-based organic stain, must absolutely never be treated with hot water. Hot water cooks the proteins in the blood, permanently bonding them to the fabric fibres. Fresh blood stains should be rinsed immediately under plenty of cold or icy water, then gently rubbed with neutral soap in circular motions. Dried blood stains should be pre-treated with a special enzyme-based stain remover before washing.

• Povidone-Iodine Antiseptic Stain Removal: Using bleach on iodine-based antiseptic stains sets and yellows the stain even further. The affected area should first be treated with alcohol, high-proof cologne, or diluted starch. Since iodine dissolves in alcohol, the stain will lift from the fabric quickly; this should be followed by rinsing with lukewarm water at 30°C.

• Bodily Fluids (Vomit, Urine, Faeces) and Cream Stains: For this type of contamination, instead of treating the stain directly while wet, first scrape off the residue from the surface with a hard plastic tool or spatula. The stained area should never be rubbed vigorously; rubbing pushes the fluid deeper into the fabric's pores. For greasy stains from medication and ointments, pre-treating with a grease-cutting dish detergent makes the stain much easier to remove completely during washing.

Golden Care Rules That Extend Your Uniform's Life

To preserve the fabric's shape while disinfecting medical uniforms, avoid using fabric softener during washing. Fabric softeners coat the fabric surface, preventing the stretch fibres from breathing, trapping air, and creating conditions over time for bad odours and bacteria to cling to the fabric surface. To prevent coloured scrubs from pilling and fading due to friction during washing, uniforms should always be washed inside out.

After the wash cycle finishes, wet uniforms should be taken out and hung quickly rather than left in the machine; damp fabric left sitting can develop microbial growth and a musty odour despite disinfection. When ironing, never press a hot iron directly onto brand logos, name embroidery, or prints on the uniform; these sections should be ironed inside out or through a protective cloth. Qule Uniform's proprietary QuleSOFT™ fabric technology, resistant to repeated washing even at sterilization temperatures as high as 90°C, with its opaque, non-see-through weave and non-iron construction, offers clinical professionals the most practical care comfort.
