How to Wash FR + Hi‑Vis Workwear (Protect Flame Resistance + Reflective Tape)

ByDavid Miller Last updated on

FR + hi‑vis garments are common in utilities, oil & gas, rail, and road work. They combine:

  • FR/arc-rated fabric (flash fire / arc hazards)
  • retroreflective trim (night visibility)

The challenge: what’s “fine” for normal laundry can damage one component or the other. This guide shows a conservative routine for FR clothing with reflective trim, based on manufacturer-style rules: FR labels plus reflective trim guidance & NFPA 2112 user-guide warnings.

Safety note: Always follow the garment care label and your workplace safety program. If gear is contaminated with fuel or hazardous chemicals, remove it from service and follow workplace procedures.

Quick Links

1) The “strictest rule wins” principle

Your garment is a system (fabric + trim + thread + closures). When rules conflict:

  1. follow the garment care label
  2. if unclear, follow the strictest compatible rule across components

This layered-care approach also supports employer duties under OSHA’s PPE guidance, which requires that personal protective equipment be maintained in a sanitary and reliable condition.

3M’s reflective trim technical sheet explicitly notes that garment care guidance should consider both the garment fabric and components like retroreflective trim. For the full wash-day routine, see our full FR clothing care guide.

2) Washing settings (safe baseline)

Temperature

3M’s reflective fabric technical data sheet defines home laundering as using consumer detergent at moderate temperatures up to 60°C / 140°F. 

Carhartt’s FR care instructions allow warm washing with caps like:

  • up to 160°F / 70°C for unlined FR
  • up to 140°F / 60°C for lined FR 

Practical baseline: A safe wash temperature is a warm wash at ≤ 60°C / 140°F (if label allows). That’s compatible with reflective trim guidance and lined FR limits.

Cycle + loading

  • normal cycle
  • don’t overload
  • turn inside out
  • wash separately from heavy abrasive items

NFPA 2112 user guidance (example: 5.11) recommends washing FR garments inside out and washing separately. Smaller loads also mean less abrasion on reflective tape from zippers and hardware.

3) Detergent and additives (what to use / avoid)

Detergent

Use a standard consumer detergent unless your employer specifies something else. For help choosing one, see our guide to picking an FR-safe detergent — look for a mild formula without added softener or bleach, and measure carefully, since detergent residue from overdosing can coat fibers and trim.

Bleach

3M’s guidance: If bleach is needed, use non-chlorine bleach only (and avoid high alkaline stain removers). 

But many FR brands prohibit bleach entirely. For example, Ariat’s FR care guidance says bleach must never be used, and explicitly says chlorine bleach and oxygen bleach (hydrogen peroxide) must never be used. 

Practical baseline: Don’t use bleach unless your garment label explicitly permits a specific type.

Fabric softener / dryer sheets

NFPA 2112 user guidance warns against fabric softener use (oil based; can contribute to fabric flammability).
Carhartt FR care also prohibits softeners.

Can you use fabric softener or dryer sheets on FR and hi-vis workwear?

No. Skip fabric softener and dryer sheets entirely. Softeners coat fibers with a waxy film that can mask flame resistance on FR garments and dull reflective tape. Use a plain mild detergent instead, and if static is a problem, line-dry or use a low-heat dryer cycle with no sheets.

4) Drying: the most common “reflective trim killer”

3M warns that tumble drying at high temperatures can limit garment life and should be considered part of the cleaning process. For the step-by-step routine, see our guide to drying hi-vis clothing without heat damage.

Some NFPA 2112 user guidance (example: 5.11) goes further and warns not to use automatic dryers if the garment has reflective trim because dryers can damage trim and negate visibility effectiveness. 

Practical baseline:

  • air dry when possible, or
  • tumble dry low and remove promptly (if label allows)

5) After-wash inspection (30 seconds)

  • reflective tape: peeling, cracking, dulling
  • seams and closure function
  • contamination smell check (fuel/solvent smell is a red flag)

3M notes performance can vary by use/maintenance and that exposure to contaminants may decrease retroreflectivity; reflective apparel exposed to contaminants should be promptly cleaned per care instructions. If tape is already peeling, cracking, or badly dulled, pull the garment from service until it’s repaired or replaced — damaged trim no longer does its job at night.

Can you wash FR and hi-vis workwear together?

Yes, if both care labels allow similar settings. Wash like colors together in warm water with a mild, FR-safe detergent, turning garments inside out. Never add fabric softener or bleach, skip heavy abrasive items, and separate the load if either label demands gentler handling.

What water temperature is safe for FR and hi-vis?

Check the care label first, then default to warm — not hot — water. A practical baseline is a warm wash at or below 60°C / 140°F when the label allows it. Hotter water wears out reflective tape faster and can shrink FR fabrics, so the strictest label setting wins.

How should you dry hi-vis workwear?

Tumble dry low or line dry — high heat is the fastest way to crack or peel reflective tape. Air-dry FR hi-vis garments when possible; if you use a dryer, choose low heat, remove garments promptly, and never use dryer sheets, which can coat fibers and dull reflectivity.
