How to Wash a Lab Coat (and Keep a White One White)

A school lab coat gets worn weekly for six years — that's a lot of washes. Here's how to wash one so it lasts, in plain English.

The Basics

  • Wash it separately the first few times, especially new navy coats — dark colours can release dye in the first washes
  • Normal machine wash, cold or warm (30–40°C) is fine for regular cleaning
  • Use ordinary detergent — no bleach needed for day-to-day washing
  • Hang it to dry — a coat on a hanger dries overnight and keeps its shape. The dryer is the fastest way to shrink a coat that then doesn't fit

Getting Marks Out of a White Coat

Science classes leave marks — here's what works:

  • Treat marks early. The older the mark, the harder it sets. A dab of laundry pre-wash spray on pen or bench marks before washing handles most of them
  • Wash white coats with whites only. Washing with dark clothes is how white coats turn grey
  • For stubborn marks: soak in a laundry soaker (e.g. nappy-soaker style products) for a few hours, then wash normally. It's gentle on fabric and shifts most science-class marks
  • Don't use chlorine bleach as a first resort — repeated use yellows the fabric and weakens the weave over years

What About Logo Printing?

Our logo printing is DTF — a print method rated to keep its quality through 50+ washes. Wash printed coats the same as any other; no special treatment needed.

Mistakes That Wreck Coats

  1. The dryer every week — shrinks and fades years early. Hang dry instead
  2. Leaving a marked coat in the school bag for weeks — marks set. A quick pre-treat at the weekend keeps it easy
  3. Washing new navy with whites — first washes release dye

The Six-Year Rule

Looked after properly, one lab coat lasts from Year 7 to Year 12 — that's exactly what it's built for, so don't be precious about it, just follow the basics above.
