How to Care for Workwear & Safety Clothing: Washing, Drying & Maintenance Guide

August 3, 2026

Why Workwear Care Matters

Professional workwear — particularly hi-vis clothing and PPE — isn't just about looking the part. Garments certified to standards like EN ISO 20471 (high visibility) must maintain specific performance characteristics to remain compliant. Incorrect washing, drying, or storage can degrade fluorescent materials, damage retroreflective tape, and invalidate the garment's certification — meaning it may no longer legally qualify as PPE.

Beyond compliance, proper care significantly extends garment life, protecting your investment and reducing replacement costs.

How to Wash Hi-Vis Clothing

Hi-vis garments require more care than standard workwear because the fluorescent dyes and retroreflective tape are sensitive to heat, harsh chemicals, and abrasion.

General Washing Rules for Hi-Vis

Check the care label first — always follow the manufacturer's specific instructions. These override general guidance.
Wash at 40°C or below — most hi-vis garments should be washed at 30–40°C. High temperatures accelerate fluorescent dye fade and can damage reflective tape adhesive.
Use a mild, non-biological detergent — biological detergents contain enzymes that can break down fluorescent coatings. Avoid detergents with optical brighteners, which can interfere with the fluorescent properties of the fabric.
Do not use bleach or fabric softener — bleach degrades fluorescent dyes rapidly. Fabric softener coats fibres and reduces the effectiveness of moisture-wicking and flame-retardant treatments.
Wash inside out — reduces abrasion on the outer fluorescent surface and reflective tape.
Wash separately or with similar colours — avoid washing hi-vis with dark or heavily soiled garments that could transfer dye or debris.
Use a gentle or delicate cycle — reduces mechanical stress on reflective tape seams and bonding.

How Many Washes Can Hi-Vis Withstand?

EN ISO 20471 requires garments to maintain their performance after a minimum number of wash cycles — typically 25 washes at 60°C for the certification test. However, washing at lower temperatures and with appropriate detergents will significantly extend this. Many quality hi-vis garments will last 50–100+ washes when cared for correctly.

Inspect garments regularly. If the fluorescent material has faded noticeably, or if retroreflective tape is peeling, cracked, or missing sections, the garment should be retired from PPE use.

How to Wash Flame-Retardant (FR) Workwear

Flame-retardant workwear requires particularly careful laundering, as incorrect washing can permanently destroy the FR treatment.

Never use bleach, fabric softener, or starch — these coat the fibres and can render FR treatments ineffective or create flammable residues.
Use FR-compatible detergents — some manufacturers specify approved detergents; check the garment documentation.
Wash at the temperature specified on the label — typically 40–60°C depending on the FR treatment type.
Do not dry clean — unless the label specifically permits it; many dry cleaning solvents damage FR treatments.
Repair or retire damaged FR garments — holes, tears, or worn areas compromise protection. FR garments should only be repaired with FR-rated materials.

How to Wash Embroidered & DTF Printed Workwear

If your workwear features custom embroidery or DTF (Direct to Film) printing — as supplied by ProAttire — a few additional steps will keep your branding looking sharp for longer.

Embroidered Workwear

Wash inside out to protect the embroidery threads from abrasion
Use a gentle cycle at 40°C or below
Avoid tumble drying on high heat — this can cause embroidery to pucker or distort
Do not iron directly over embroidery — use a pressing cloth or iron on the reverse

DTF Printed Workwear

Wash inside out — this is the single most important step for preserving DTF prints
Wash at 30–40°C on a gentle cycle
Avoid tumble drying where possible; air dry instead
Do not iron directly on the print — iron on the reverse or use a pressing cloth
Do not dry clean

ProAttire's DTF printing uses high-quality film and adhesive for durability, but following these steps will maximise the life of your branded garments. Read more about our DTF printing process.

Drying Workwear Correctly

Air dry where possible — hang garments on a line or airer away from direct sunlight. UV exposure accelerates fluorescent dye fade.
Tumble dry on low heat only — if tumble drying is necessary, use the lowest heat setting. High heat damages reflective tape, FR treatments, and print adhesion.
Do not dry on radiators — concentrated heat from radiators can warp reflective tape and damage waterproof membranes in hi-vis waterproofs.
Ensure garments are fully dry before storage — storing damp workwear encourages mildew and can degrade fabric treatments.

Ironing & Pressing

Most hi-vis garments should not be ironed — heat can melt or distort retroreflective tape. Check the care label.
If ironing is permitted, use a low heat setting and avoid the reflective tape entirely.
For embroidered or printed garments, always iron on the reverse side or use a pressing cloth.

Storage & Maintenance

Store in a cool, dry place away from direct sunlight — UV degrades fluorescent materials even when garments are not being worn.
Hang rather than fold where possible — repeated folding along the same crease lines can weaken reflective tape over time.
Inspect before each use — check for damage to reflective tape, seams, zips, and the fluorescent material itself. A quick visual check takes seconds and could prevent a compliance issue on site.
Keep a replacement schedule — even well-maintained workwear has a finite life. For teams, consider a rolling replacement programme rather than replacing everything at once.

When to Replace Workwear

Retire a garment from PPE use when any of the following apply:

Fluorescent material has faded significantly (hold against a new garment to compare)
Retroreflective tape is peeling, cracked, lifting at edges, or missing sections
Fabric is torn, holed, or heavily worn in a way that cannot be repaired
Waterproof membrane has failed (water no longer beads on the surface)
FR treatment integrity is in doubt due to damage or incorrect laundering
The garment no longer fits correctly — ill-fitting PPE is non-compliant PPE

Faded or damaged hi-vis can still be used for non-PPE purposes (e.g. general visibility in low-risk areas), but should be clearly distinguished from compliant PPE garments to avoid confusion on site.

Bulk Laundry for Teams

If you're managing workwear for a team, consider establishing a simple laundry protocol:

Label garments with the wearer's name or number to avoid mix-ups
Set a wash frequency — weekly as a minimum for most site environments
Designate a responsible person to inspect garments and flag replacements
Keep a log of garment issue dates to track age and wash cycles
