**Résumé :** **In short:** laundry soaked by a flood (river flood, leak,
sewer overflow)? **First: insurance claim** + photos BEFORE
sorting. **Identify the nature of the water** (clear rain,
river, urban sewer) to scale your response.
**4-level triage**: simple recoverable / hot wash +
disinfectant / specialized dry cleaning / discard.
**Hot wash 60-90 °C (140-194 °F) + bleach** on white cotton per
CDC. **Discard soaked foam mattresses, pillows, and plush toys**
— the contaminated water stays trapped. Drive-up laundromat 18 kg (40 lb) +
pro dryer for large volumes.

## At a glance

- **Photos BEFORE sorting** for the insurance claim (gouvernement.fr).
- **PPE required**: nitrile gloves, FFP2 mask, boots (possible sewage water).
- **Identify the nature of the water**: clean rain vs. river vs. urban sewer.
- **Hot wash 60-90 °C (140-194 °F)** per care label + diluted bleach on white cotton (CDC).
- **Complete immediate drying** in a high-temperature tumble dryer (anti-mold per Anses).
- **Soaked foam mattresses, pillows, plush toys = discard**, deep disinfection is impossible.

## First: insurance claim + safety

Flood = disaster. **Priority order**:

1. **Safety**: cut the electricity in flooded zones, do not walk barefoot, do not enter a room with deep water without PPE.
2. **Photos BEFORE sorting**: document the entire state of the home and belongings for the insurance. The French government explicitly recommends this.
3. **Disaster declaration** within the deadlines of your contract (typically 5 days for the flood/natural disaster coverage).
4. **PPE** for handling: nitrile gloves, FFP2 mask (minimum), waterproof boots. Flood water can contain pathogens — see below.

> **Warning:**
> - **Do not turn on the washing machine** if the outlet or electrical circuit was touched by water — electrocution risk.
> - **Do not mix** bleach with any other household product (acid, ammonia) — toxic gas per Anses.
> - **Pregnant women, children, immunocompromised people**: have a third party handle the contaminated laundry.

## Identify the nature of the water

Not all flood water is equivalent. Contamination determines the protocol:

| Nature of the water | Health risk | Approach |
|---|---|---|
| Pure rainwater (roof, cold water leak) | Low | Normal wash + complete immediate drying |
| Clear river water (rural flood) | Moderate | 60 °C (140 °F) wash + percarbonate, hot drying |
| Basement water / old leak | Moderate to high (likely mold) | Sanytol pre-treatment + 60 °C wash + hot drying |
| Urban flood water / sewer overflow | High (possible pathogens) | Hot wash 60-90 °C + bleach on white cotton, or discard |

According to **Santé publique France** and the **CDC**, urban flood waters can contain **pathogens** (bacteria such as E. coli or salmonella, viruses, parasites) from sewer overflow or household wastewater. The risk is invisible but real.

## Sorting the laundry

Before any washing, **sort**:

| Textile type | Clean / river water | Sewage / contaminated water |
|---|---|---|
| Cotton/linen/sturdy polyester (sheets, towels, t-shirts) | 60 °C wash + percarbonate | Hot wash 60-90 °C + diluted bleach on white cotton |
| Wool, silk, cashmere | Specialized dry cleaning, inform them of the disaster | Dry cleaner or discard (depending on value) |
| Soaked foam mattresses, pillows, plush toys | Discard (trapped water, unavoidable mold) | Discard without hesitation |
| Valuable garments / one-of-a-kind pieces | Professional dry cleaner | Premium dry cleaner or disposal depending on contamination |
| Baby / immunocompromised laundry | 60-90 °C + textile disinfectant | Discard as a precaution if heavily soiled |

## Washing protocol (CDC)

For recoverable laundry:

1. **Pre-rinse** in cold water outside or in a dedicated tub (not directly in the machine — mud + sewer residue)
2. **Wash**: cotton program **60 °C (140 °F) minimum** per GINETEX care label (ISO 3758). **90 °C (194 °F) on durable white cotton** if heavily contaminated.
3. **Detergent**: your regular laundry detergent, normal dose
4. **Diluted bleach** per the manufacturer's instructions for **white cotton only** — discolors colored items and degrades synthetics per Anses
5. **Sodium percarbonate**: alternative for colored textiles (2 tbsp in the drum, active from 40 °C / 104 °F)
6. **IMMEDIATE drying**: high-temperature tumble dryer (recommended) or hang in a well-ventilated room outside the damp zone. No wet laundry sitting in a basket.

**Disposable nitrile gloves (box of 100)**

Essential protection for handling laundry flooded by sewage water. Latex-free, standard size, suitable for sanitary use.

## Special cases

### Complete bedding

Sheets, duvet covers, duvets flooded as a batch. Too bulky for the home machine. Head to the 18 kg (40 lb) laundromat: a single cycle at 60 °C + professional high-temperature dryer. Transport in closed garbage bags to avoid contaminating your route or trunk.

### Children's plush toys

If the stuffing is foam OR if the plush toy is heavily soiled with urban flood water: **discard** without hesitation. Child safety. If washable fiber stuffing and clean water: 60 °C machine wash in a mesh bag + hot tumble dryer + inspect the seams afterward.

### Rugs and carpets

Outside the laundromat's scope — specialized professional disaster cleaning OR disposal if the carpet is soaked with sewage water.

### Branded clothing / one-of-a-kind pieces

Head to a **premium dry cleaner**, clearly informing them of the disaster. If the value doesn't justify the cleaning cost (€300-500 for heavily contaminated pieces), accept the loss (home insurance often covers it).

## The post-flood mold risk

According to **Anses**, mold develops in damp, confined conditions — exactly the post-flood context. Any poorly dried textile will mold within a few days. Consequences: persistent odor, stains, triggered allergies/asthma.

**Anti-mold measures**:

- **Complete immediate drying** after washing (tumble dryer or ventilated room)
- **Ventilate the home** for several days after the flood
- **Dehumidifier** if possible in affected rooms
- **Monitor** the textiles for 2-3 weeks: if the musty smell appears, take them out and rewash at 60 °C + percarbonate

## When to use the laundromat

This is typically when the laundromat becomes indispensable:

- **Large volume**: complete bedding + a family's clothes in one batch
- **Home machine unusable** (water in the basement where it sits)
- **Reliable hot wash 60-90 °C needed**: our machines guarantee the actual temperature (no eco mode cheating)
- **Professional high-temperature dryer**: essential to neutralize residual mold
- **Detergent and softener included**: nothing to bring

Transport in a double sealed bag (sewage water). Wash your hands thoroughly after loading the machine.

## Mistakes to avoid

- 🚫 **Sorting before photos** — Insurance requires proof of the initial state. Photograph EVERYTHING before handling.
- 🚫 **Handling with bare hands** — Sewage water = possible pathogens. Nitrile gloves + FFP2 mask + boots required.
- 🚫 **Loading the machine without pre-rinsing** — Mud + sewer residue straight into the drum = contamination of the machine and the next load.
- 🚫 **Trying to save soaked foam mattresses/plush toys** — Contaminated water stays trapped in the core of the stuffing. Deep disinfection is impossible. Discard.
- 🚫 **Air drying in a damp room** — Immediate recontamination by environmental mold. Tumble dryer or ventilated room outside the affected area.
- 🚫 **Mixing bleach + another product** — Anses: risk of toxic chlorine gas. Bleach alone on white cotton, never mixed.
