Flame Acid Retardant (FAR) overalls are essential for workers in high-risk environments like mining, oil and gas, and heavy industry. These specialised garments are designed to protect workers from hazardous conditions such as heat, flames, and chemical splashes. However, they’re not immune to getting dirty — especially with stubborn oil stains that can compromise both the appearance and effectiveness of the gear.

Whether you’re a safety officer or a worker trying to keep your PPE in top shape, here’s how to safely and effectively remove oil stains from your flame acid retardant overalls, without damaging the protective properties.

1. Act Quickly

The sooner you treat an oil stain, the easier it will be to remove. Letting the stain sit allows it to soak deeper into the fibres, making removal more difficult and potentially reducing the effectiveness of the flame-retardant treatment.

2. Pre-Treat the Stain

Start by gently blotting (not rubbing) the excess oil with a clean paper towel or cloth. Then, apply a small amount of liquid dishwashing detergent directly onto the stain. Dishwashing liquid is designed to cut through grease, making it ideal for oil stains.

Let the detergent sit on the fabric for 5 to 10 minutes to break down the oil.

Pro Tip: Avoid using bleach or fabric softeners, as these can interfere with the flame-resistant properties of the overalls.

3. Use Hot Water — With Caution

Rinse the treated area with warm (not hot) water. Excessive heat can damage the flame retardant treatment, so always follow the manufacturer’s washing instructions. If in doubt, opt for lukewarm water.

4. Machine Wash Safely

Place the overalls in a washing machine on a gentle cycle. Use a mild detergent that is free from bleach, fabric softeners, and any additives that could break down the FAR coating.

Some laundry services even offer industrial PPE cleaning with specialised products designed to preserve the integrity of protective clothing.

5. Air Dry, Don’t Tumble

After washing, hang your overalls to air dry. Tumble drying can expose the garment to high temperatures, which may compromise its protective properties. Always avoid ironing the stained area until you're sure the oil is completely gone, as heat can permanently set the stain.

6. Repeat if Necessary

Oil stains can be stubborn. If the stain persists after the first wash, repeat the process. It's better to go through two gentle cleaning cycles than one harsh one that risks damaging your gear.
