What Laundry & Fabric Care covers
This section covers laundry products and fabric care: detergents, fabric softeners and the questions people have about what each one actually does.
Fabric softener is the product most worth understanding, because what it does is not what most people assume. It does not clean. It coats fibres with a thin lubricating layer, which makes fabric feel softer, reduces static and adds fragrance. That coating is the entire mechanism, and it explains every limitation the product has.
Because it works by coating, fabric softener should not be used on several common fabrics. Towels lose absorbency as the coating builds up, which is why old towels sometimes push water around instead of soaking it up. Microfibre cloths stop working almost entirely, since their cleaning action depends on the fibre surface. Activewear and technical fabrics lose their moisture-wicking properties. And flame-retardant items, including children’s sleepwear, can have that treatment compromised — which is a safety consideration rather than a performance one.
The other recurring question is whether dishwashing liquid can be used for laundry. It can be used to spot-treat a greasy mark by hand, but it must never go into a washing machine, where it foams enough to overflow.

How the guides in this section differ
Cleaning or conditioning. Detergent removes soil. Softener coats fibres afterwards. They are sequential, not alternatives, and softener does nothing to help anything get clean.
Machine or hand product. Products are formulated for controlled foaming in a machine or for hand washing. Hand dishwashing liquid in a washing machine causes an overflow; machine detergent is too harsh for prolonged skin contact.
Fabric type decides suitability. Towels, microfibre, activewear and flame-retardant items should not be softened. Cotton bedding and general clothing are where softener earns its place.
| Product | What it does | Use on | Avoid on |
|---|---|---|---|
| Laundry detergent | Removes soil and stains | Everything washable | — |
| Fabric softener | Coats fibres; softness, static, scent | Cotton clothing, bedding | Towels, microfibre, activewear, flame-retardant items |
| Dishwashing liquid | Cuts grease | Hand spot-treating a greasy mark | Any washing machine |
| Stain remover | Targets specific stains | Pre-treatment | Fabrics its label excludes |

Safety, accuracy and next-step checks
These guides follow product labels and care symbols. Where a garment’s care label differs from general advice, follow the label.
Points worth carrying:
- Never put dishwashing liquid in a washing machine. It foams far beyond what the machine can handle and floods the floor.
- Laundry capsules are a serious poisoning risk for children. They are brightly coloured, soft and resemble sweets. Concentrated contents cause chemical burns to mouth and eyes. Store them sealed, high and out of reach — this is one of the most common household poisoning presentations involving young children.
- Do not use softener on flame-retardant sleepwear. The coating can compromise the treatment.
- Never mix laundry products with bleach-based cleaners unless the label specifically permits it.
- Do not overdose detergent. Excess does not clean better; it leaves residue that stiffens fabric and irritates skin, and residue is a frequent cause of what people assume is a skin allergy.
- Check the care label before washing anything unfamiliar, particularly for temperature and whether it can be machine washed at all.
- Fragrance is a common irritant. For sensitive skin, eczema or infant clothing, fragrance-free detergent and skipping softener is the usual advice.
- If a capsule is bitten or splashed in an eye, rinse immediately and seek medical help, taking the packaging.
If clothes are coming out stiff, grey or smelling faintly stale, the cause is usually one of three things and none of them require a new product. Too much detergent leaves residue that stiffens fabric and traps odour. Overloading prevents proper rinsing. And a machine that only ever runs cool washes builds up a residue film in the drum, which a periodic hot maintenance wash clears. Working through those three fixes more laundry problems than any change of brand.
Frequently asked questions
What is fabric softener actually for? It coats fibres to make fabric feel softer, reduce static and add fragrance. It does not clean, and it does not help detergent work.
Why should I not use it on towels? The coating builds up and reduces absorbency. Towels that have stopped soaking up water have usually been softened repeatedly.
Can I use dishwashing liquid to wash clothes? Only by hand, to spot-treat a greasy mark. Never in a machine — it foams and overflows.
Does more detergent clean better? No. Excess leaves residue that stiffens fabric and irritates skin. Follow the dosing guidance for your load size and water hardness.
Is fabric softener safe for baby clothes? Many people skip it for infants, and fragrance-free detergent without softener is the usual recommendation for sensitive or eczema-prone skin. Never use it on flame-retardant sleepwear.
