**Résumé :** **In short:** microfiber doesn't wash like cotton.
**No fabric softener** (it clogs the capillaries and kills
absorbency — Vileda and 3M rule). **40-60°C maximum** per the
GINETEX label. **Separate from cotton and wool** (velcro effect
\= lint). **Low-temperature drying** or air dry. To reduce
**microplastics**, ADEME recommends a wash bag (Guppyfriend) +
low temperature. 18 kg laundromat washer for large loads (clubs, pro
detailing).

## At a glance

- **No fabric softener** — clogs the ultra-fine capillaries (Vileda, 3M).
- **40-60°C max** depending on use and ISO 3758 label — melting risk beyond that.
- **Separate from cotton and wool** — microfiber attracts lint.
- **Low-temperature drying** or air dry per the care label.
- **Microplastics**: Guppyfriend wash bag + low temperature (ADEME).
- **Lifespan**: several hundred cycles; replace when absorbency drops.

## Why microfiber needs special care

Microfiber is a synthetic textile (typically polyester + polyamide) with **ultra-fine** fibers. This fineness creates a **capillary structure** that:

- **Traps particles by electrostatic effect** (dust, lint, fine particles)
- **Absorbs water inside the capillaries** (up to several times its weight for quality microfiber)
- **Dries faster than cotton** thanks to the high surface area

The problem: anything that **clogs the capillaries** destroys these properties. That's why **care rules are strict** and different from cotton.

## Table by use

| Use | Max temperature | Bans / precautions |
|---|---|---|
| Pool, beach, sport towels | 60°C (check label) | No softener; separate from cotton |
| Kitchen / household cloths | 60°C | No softener; percarbonate OK |
| Microfiber sportswear | 30-40°C | No softener; synthetics cycle |
| Auto detailing cloths | 40-60°C | Strict separation: grease vs polish |
| Microfiber mop heads | 60°C | Wash separately (chemical residue) |

## Microfiber towels (pool, beach, sport)

The most common use:

1. **Pre-rinse** in cold water if heavily loaded (pool chlorine, sea salt)
2. **Cotton program at 40-60°C** depending on the label
3. **Regular detergent**, normal dose
4. **NO fabric softener** — pour a dose of **white vinegar** into the softener compartment instead, to neutralize limescale
5. **Separate** from any cotton terry towel (lint)
6. **Low-temperature dryer** or air dry on a line

**Guppyfriend anti-microplastic wash bag**

Wash bag that captures microplastics released by synthetic fibers. Recommended to reduce the environmental impact of washing synthetic textiles.

## Microfiber household cloths

- Wash at **60°C** (cotton program) with regular detergent
- **2 tablespoons of percarbonate** in the drum if cloths are greasy or stained (active oxygen from 40°C, without the clogging effect of softener)
- **Separate kitchen cloths** from **bathroom/sanitary cloths** to avoid cross-use
- Air dry or low-temperature dryer

## Microfiber sportswear

Running shirts, leggings, technical garments:

- **Synthetics program at 30-40°C** (high temperatures degrade the fibers)
- **Light detergent dose** (body odors are handled by frequency, not by dose)
- **NO fabric softener**, ever
- **Air dry** or **low-temperature dryer** (high heat = deformation of technical membranes)

## Auto detailing cloths

The most demanding use:

- **Absolute separation** between polishing cloths (paint, clear coat) and greasy cloths (wheels, engine)
- Wash at **40-60°C** in a dedicated machine if possible, otherwise an isolated cycle
- **NO fabric softener**, ever
- **Basic, fragrance-free detergent** (fragrances leave visible residue on paint)
- Air dry, **no tumble drying** for premium polishing cloths

## Microplastics: the ecological side

**ADEME** warns about microplastics released when washing synthetic textiles — microfiber is one of them. The practical solutions:

1. **Microplastic wash bag like Guppyfriend** that retains fibers during the cycle
2. **Low-temperature washing** (40°C instead of 60°C) — less friction, less release
3. **Don't overload** the machine — less friction between garments
4. **Air dry** whenever the use case allows

## When to use the laundromat

The laundromat becomes relevant for **professional or club volumes**:

- **Swim club**: pool towels after a session
- **Diving / surf school**: wetsuits and microfiber towels in bulk
- **Pro auto detailing service**: 30+ cloths per polishing session
- **Hair salon**: microfiber towels for client use

The **18 kg machine** handles a large uniform load in a single cycle, detergent included. For 3-5 kitchen cloths or a personal towel, stick with your home machine.

## Mistakes to avoid

- 🚫 **Using fabric softener** — The #1 killer of microfiber. Clogs the capillaries and destroys absorbency in just a few washes.
- 🚫 **Mixing with cotton/wool** — Velcro effect: microfiber attracts lint. Always run a separate cycle.
- 🚫 **Washing at 90°C** — Risk of melting / deformation of synthetic fibers. Respect the GINETEX ISO 3758 symbol.
- 🚫 **High-heat tumble drying** — Same issue: deformation, loss of elasticity, shorter lifespan. Low heat or air dry.
- 🚫 **Ignoring microplastics** — No miracle solution, but Guppyfriend + low temperature reduce the impact (ADEME).
