How to Run an In-House Food Processing Coat Laundry for Your Food Business

Buying washable coats is the easy decision; running the laundry that keeps them food-safe is the actual program. And it's a decision with real money on it: a food worker's coat typically needs washing around five times per week — a fresh coat every shift plus splash replacements — which is ~260 washes per worker per year. Hand that volume to an outsourced commercial laundry and you'll pay their per-garment rate on every one of those washes; run it in-house and you pay detergent and energy instead. Done right, an in-house wash operation is simple, cheap and auditable. Done vaguely, it's the weak link an inspector finds first. Here's the practical setup.

First: In-House vs Outsourced, at Real Volumes

At five washes per worker per week, the arithmetic per worker per year (illustrative — slot in your actual laundry quote):

Outsourced commercial laundry: commonly priced per garment per wash (~$2–3 including collection and return) → $520–780 per worker per year, every year, forever
In-house washing: ~$1–2 per wash all-in (energy, detergent, water, labour share) → $260–520 per worker per year
The difference: a few hundred dollars per worker per year — multiply by the team

Outsourced laundry earns its price when a business has no machine, no space and no staff minutes — it's genuinely the right call for some small sites. But if you already own a commercial or heavy-domestic machine, you are paying a service to run it for you. The five-rules setup below is what makes in-house work.

Rule 1: Three Coats Per Worker

Five washes a week means the rotation has to be robust. The number that makes in-house laundering actually work:

One on the worker
One clean in the cupboard (ready for tomorrow, no morning scramble)
One in the wash cycle

Two coats per worker is survivable; three removes the day the machine breaks or the shift runs long. For a 20-person line, that's 60 coats — which is one Purchase Order (free shipping over $100, 24-hour dispatch on stock, no minimum).

Rule 2: Wash to the Care Label — and Within the Fabric Spec

The coat's protection depends on laundering that stays inside the spec:

Hot wash at the hottest the care label permits — for our coats the fabric is rated for hot washing with dimensional stability of 3% maximum, so a proper hot cycle doesn't compromise the fit (details in our shrinkage article)
Ordinary detergent plus chlorine bleach does the job — the bleach is the sanitiser your food safety auditor expects to see on the wash procedure. Food handling regulations require a chlorine sanitiser cycle on staff coats; it's not optional. An oxygen-based soaker can be added for the grey drift white coats develop over time (see the stain guide for treatment specifics), but it supplements the chlorine cycle, it doesn't replace it
That's exactly why we recommend plain coats (no printed logos) for food processing. Chlorine bleach will fade a DTF print well before it fades the fabric — so a printed coat in a food plant is a coat that will lose its logo. Plain coats take the chlorine cycle every wash with nothing to degrade but the fabric, which is built for it. The 220gsm poly-cotton is rated for repeated hot wash-and-bleach cycles; follow the dilution ratio on the bleach label and stay within the care label's temperature guidance
Air dry or low heat. Repeated hot tumble cycles are the fastest way to retire a coat early

Rule 3: Segregate the Wash

Food processing coats from the production floor wash separately from other site laundry — never with cleaning cloths, never with personal clothing, and never mixed between high-risk and low-risk areas if your site operates zoning. Dirty coats go into a closed bin at the gowning point, not carried through the plant under an arm.

Rule 4: Inspect at Fold-Up

The single most valuable ten seconds in the program: every coat gets a two-minute-style check as it comes off the line (the full checklist is in our replacement guide):

Seams and shoulders intact, no thin patches or pinholes when held to the light
All press studs present and gripping
Elastic cuffs still snug at the wrist
No persistent chemical or grease staining

Anything failing goes to the rag bin or replacement stock — never back to the cupboard. Budget ~10% coat replenishment per year for damage and turnover; it's a standing line, not a surprise.

Rule 5: Keep the Paperwork the Auditor Asks For

When food safety asks about staff clothing, the answers that satisfy them are: a written laundering procedure (temperature, frequency, segregation), a coat-issue record per worker, and an inspection/replacement log. That's one page of SOP text and one spreadsheet — an afternoon to set up, and it converts "we wash them somewhere" into "here is our controlled process."

Why This Beats Disposables — In One Line

A controlled in-house wash is a process you own and can prove; a bin of disposables is a consumable cost you can't audit after the fact. The full cost comparison — including the per-worker arithmetic — is in Washable vs Disposable: the real cost comparison.
