How to Wash Carhartt Jackets & Duck Canvas.

Duck canvas is tough. Laundry can still ruin it.

We are a trades-first laundry company building concentrated formulas that pull embedded job-site soil out in one wash — without bleach, softeners, or optical brighteners that wreck FR gear and reflective tape.

Built with input from 412+ tradesmen in our field-trial cohort

Carhartt jackets, duck canvas pants, bibs, and work coats are built for abuse. That does not mean they are impossible to wreck.

The wrong wash routine can shrink duck canvas, fade the color, stiffen the fabric, weaken fibers, and lock oil stains into the weave.

Why duck canvas needs different care

Duck canvas is tightly woven, durable, and built to handle work. That tight weave also holds onto oil, grease, diesel residue, and detergent buildup.

If you use hot water, harsh additives, heavy fragrance, optical brighteners, or high dryer heat, the fabric can shrink, fade, and stiffen.

Step-by-step: washing Carhartt and duck canvas

1. Empty pockets and close zippers

Remove tools, screws, wrappers, earplugs, receipts, nails, and whatever else your pockets have been hoarding.

2. Turn the garment inside out

This helps protect the outer face of the fabric, logos, hardware, and reflective trim if present.

3. Pre-treat grease and oil stains

Duck canvas holds petroleum hard. Pre-treat grease, diesel, oil, and grime before washing.

4. Wash cold or warm, not hot

Hot water can shrink duck canvas and accelerate fading. Use cold or warm water depending on the garment label and soil level.

5. Use a residue-free detergent

Avoid detergent that leaves heavy scent, softener, optical brighteners, or unnecessary coating behind.

6. Air dry or tumble low

High heat can shrink duck canvas and weaken fibers. Air drying is safest. If using a dryer, tumble low.

How to soften stiff duck canvas

  1. Wash with a clean-rinsing detergent.
  2. Skip fabric softener.
  3. Use an extra rinse cycle.
  4. Air dry or tumble low.
  5. Repeat over several washes.

What to avoid on duck canvas
