How to Remove the 5 Most Common School Uniform Stains

Step-by-step treatment for grass, mud, ink, grease and blood — because school happens.

School uniforms attract stains like magnets. The good news is that almost every common stain is treatable — if you use the right method and act quickly. Here's how to handle the five stains that WA school parents deal with most often.

The golden rule for all stains: Never put a stained garment in a hot dryer. Heat sets stains permanently. Always check that a stain is fully gone before drying.

1. Grass Stains

Grass stains are a combination of chlorophyll (a green pigment) and protein — which is why they need a specific approach rather than just soap and water.

  1. 1Don't wet the stain first — this sets it deeper into the fibres.
  2. 2Pre-treat with a small amount of liquid laundry detergent or white vinegar directly on the stain.
  3. 3Leave for 10–15 minutes, then work it in gently with an old toothbrush using circular motions.
  4. 4Wash at 40°C with a biological detergent (one that contains enzymes).
  5. 5Check before drying — if the stain remains, repeat. Never put a stained garment in the dryer.
Pro tip: Rubbing alcohol applied before washing can break down the chlorophyll in stubborn grass stains.

2. Mud

The instinct is to wipe mud off immediately — resist it. Wet mud spreads and embeds itself further into fabric fibres.

  1. 1Let the mud dry completely first. This is the most important step.
  2. 2Once dry, shake or brush off as much as possible with a stiff brush.
  3. 3Pre-soak in cold water with a tablespoon of laundry detergent for 30 minutes.
  4. 4Wash at 40°C on a normal cycle.
  5. 5For dried-in mud on light fabrics, a paste of bicarbonate of soda and water left for 30 minutes before washing works well.
Pro tip: Never use hot water on a fresh mud stain — heat sets the clay particles into the fabric permanently.

3. Ink (Ballpoint & Felt-Tip)

Ballpoint ink is oil-based; felt-tip is water-based. They need different treatments, but both respond poorly to hot water.

  1. 1For ballpoint: apply rubbing alcohol or hand sanitiser to the stain, blot with a clean cloth. Repeat until the ink lifts, then wash cold.
  2. 2For felt-tip/marker: run cold water through the back of the stain to push the ink out. Apply liquid detergent, leave 5 minutes, then wash cold.
  3. 3Dab — never rub — to avoid spreading the ink.
  4. 4Wash at 30°C after pre-treatment.
Pro tip: Hairspray used to work well on ballpoint ink due to its alcohol content, but modern formulas are less effective. Rubbing alcohol is more reliable.

4. Food Grease & Oil

Canteen lunches, cooking classes and lunchboxes make grease stains a school uniform regular. The key is absorbing the oil before it spreads.

  1. 1Blot — don't rub — the excess grease immediately with a paper towel.
  2. 2Sprinkle bicarbonate of soda or cornflour generously over the stain and leave for 15–20 minutes to absorb the oil.
  3. 3Brush off the powder, then apply a small amount of dishwashing liquid (dish soap is formulated to cut through grease) directly to the stain.
  4. 4Leave for 10 minutes, then wash at the hottest temperature the care label allows.
Pro tip: Dishwashing liquid is genuinely one of the most effective treatments for grease stains on fabric — keep a bottle near the laundry.

5. Blood

Blood is protein-based — heat sets it permanently. Cold water is essential.

  1. 1Act immediately. Rinse the stain under cold running water — never warm or hot.
  2. 2For fresh blood: soak in cold salted water for 30 minutes, then wash cold.
  3. 3For dried blood: make a paste of bicarbonate of soda and cold water, apply to the stain, leave 30 minutes, then rinse cold before washing.
  4. 4Hydrogen peroxide (3%) applied to light-coloured fabrics can break down dried blood — test on a hidden area first.
  5. 5Wash at 30°C — never higher.
Pro tip: Biological (enzyme) detergents are particularly effective on blood and other protein-based stains — worth keeping one in the laundry.
