Yes, most fire-retardant clothing can go through a home washing machine. Home laundering keeps FR garments safe and effective as long as you follow the care label, skip bleach and fabric softener, and remove flammable residue before the next wear. This applies to both treated fabrics and inherently flame-resistant fibers, though the exact rules can shift depending on the fabric type.
FR clothing only works if it still meets the safety standard it was built for. A shirt or coverall that has lost its protective properties through bad laundering can burn longer or catch fire faster during an arc flash or flash fire, even though it looks fine on the hanger. That’s a real risk for anyone who depends on this gear daily in hazardous environments.
Getting the wash routine right isn’t complicated, but it does take attention to a few details most people skip with regular laundry. We’ll walk through when home washing works, which products to avoid, and how to tell when a garment needs replacing. If you’re shopping for new FR workwear or fabric built to hold up wash after wash, Levitex’s product lineup is worth a look.
When Home Laundering Is Appropriate
Home laundering works for most FR garments and is often the better choice over industrial laundering. It’s cheaper, more convenient, and when done right it doesn’t shorten the life of the fabric.
Home washing follows ASTM F2757, the standard guide covering home laundering care for flame-resistant and arc-rated clothing, according to Tyndale USA. This standard lays out what a safe home wash process looks like and when a garment needs professional handling instead, based on details from ASTM International.
What Should You Check Before Cleaning FR Garments?
Always read the care label first. It tells you the exact water temperature, drying method, and any fabric-specific warnings.
Skip this step and you risk voiding the flame-resistant treatment or shrinking the garment beyond repair.
How Do Treated and Inherent FR Materials Differ?
Treated FR fabrics get their flame resistance from a chemical finish applied to fibers like cotton. Inherently flame-resistant fibers, such as Nomex, are built flame-resistant at the molecular level and can’t lose that trait through washing.
Treated fabrics need more careful handling since harsh chemicals or heat can strip the finish over time. Inherent fibers are more forgiving but still need clean, contaminant-free washing to meet standards like NFPA 2112 and ASTM F1506 for arc-rated clothing used against arc flash and flash fires.
When Should a Garment Go to an Industrial Laundry Service Instead?
Heavy chemical contamination changes the equation. Garments soaked in solvents, oils, or other flammable residue need an industrial laundry service equipped to strip those substances safely.
Tyndale USA notes that industrial laundering may be the better option for workers whose garments get severely soiled on a regular basis, while home laundering tends to extend garment life for lighter, routine soiling. Washing heavily contaminated gear at home also risks cross-contamination with household laundry, which raises real fire hazards.
How to Machine-Wash FR Workwear Safely
A standard washing machine works fine for most FR workwear, as long as you use the right detergent, water temperature, and cycle. Skipping the wrong laundry additive matters just as much as picking the right one.
Which Detergents and Additives Should You Avoid?
Plain liquid detergent is the safest bet. Tyndale worked with Procter & Gamble to identify Liquid Tide and Liquid Tide HE as detergents that clean well without harming FR finishes, according to Tyndale USA.
Avoid these laundry additives entirely:
- Chlorine bleach or any oxidative/non-chlorine bleach
- Hydrogen peroxide-based products
- Fabric softener, including detergent with softener built in
- Starch
- Natural soaps not designed for FR fabric
Bleach can degrade FR characteristics and reduce protective properties, based on findings shared by Tyndale USA. Starch itself doesn’t break down flame resistance, but it’s a flammable substance that shouldn’t sit on the fabric surface. The same goes for insect repellents containing DEET, which can propagate flame during an arc event.

What Water Temperature and Wash Settings Should You Use?
Warm water, generally around 140°F (60°C) for heavily soiled loads, works best for FR clothing. Hot water isn’t necessary for routine washing and can add unneeded wear.
Wash FR garments inside out and in small loads. This reduces abrasion and helps the detergent rinse out fully.
Keep FR clothing separate from regular household laundry. Mixing loads risks transferring contaminants onto the FR fabric, undoing the safety benefit of washing it carefully in the first place. Hard water areas may need a water softener added to the wash to help detergent perform properly and rinse clean.
How Can You Remove Oil Stains Without Leaving a Fire Risk?
Spot-treat oil stains with detergent before the wash cycle starts. Rubbing a small amount directly onto the stain and letting it sit for a few minutes helps break down the oil before the machine cycle begins.
Check the garment after washing. If an oil or grease stain remains, that’s a flammable residue that can ignite during an arc flash even if the FR fabric self-extinguishes elsewhere on the garment. A garment with a stain that won’t wash out should be pulled from service rather than risking body burn on the job.

Drying, Inspection, and Replacement Decisions
Tumble drying on low heat is safe for most FR clothing, and a quick inspection after every wash catches problems before they become safety risks. Getting drying and inspection right extends the life of the garment and keeps its protective properties intact.
Can You Tumble-Dry or Line-Dry FR Clothing?
Tumble dry on low heat, or line dry when possible. High heat causes most of the shrinkage FR garments experience, and pulling a garment out while still damp helps avoid over-drying.
Two-thirds of a garment’s total shrinkage happens within the first five washes, according to Tyndale USA. Skip dryer sheets entirely, since they leave the same kind of coating that fabric softener does.
Our article on how to dry fire retardant clothing covers specific settings by fabric type, and our piece on whether fire retardant clothes shrink breaks down what to expect over repeated washes.
What Should You Inspect After Each Wash?
Check for holes, tears, thinning fabric, and frayed seams every time a garment comes out of the wash. Damaged closures and worn-out fabric both reduce the protection a garment can offer during a fire hazard.
Look closely at areas that see the most friction, like elbows, knees, and pockets. These spots wear thin first and are easy to miss during a quick glance.
When Is Dry Cleaning or Garment Replacement Necessary?
Dry cleaning works well for stubborn stains that home washing can’t remove. FR garments can be dry-cleaned at any point in their service life without harming flame resistance.
Replace a garment once it has permanent flammable staining, exposure to bleach, or structural damage like tears and thinning fabric. To understand typical service life expectations, our guide on how long fire retardant clothing lasts walks through the factors that shorten or extend a garment’s usable life.
