Wash towels every three to four uses on a warm-to-hot cycle (around 40 to 60 degrees Celsius) with a moderate dose of detergent and no fabric softener, then dry them promptly. That single routine prevents almost every common towel problem: stiffness, lingering smells and lost absorbency. The rest of this guide explains each step, and why the small mistakes that ruin towels are so easy to avoid.
How often should you wash towels?
Wash a bath towel after every three to four uses, and sooner if it has not dried fully between uses. A towel is damp, warm and covered in dead skin cells after every use, which is exactly what bacteria and mildew need to grow. The three-to-four-use rule assumes the towel dries completely on a rail in between; if your bathroom is humid or the towel stays bunched up, wash more often.
Wash immediately when a towel smells musty, has been used on broken skin or wounds, or has been shared during illness. Gym and sweat towels need washing after every single use. For the full reasoning, see how often to wash towels and our towel hygiene guide.
What temperature should you wash towels at?
Wash towels warm to hot, typically 40 to 60 degrees Celsius, because heat is what actually removes body oils and reduces bacteria. A 40-degree wash suits everyday cleaning and coloured towels; a 60-degree wash gives a more thorough sanitising clean and is useful for white towels, heavily used towels, or after illness.
Cooler washes save energy but clean less effectively and let smells build up over time. If you wash cool for environmental reasons, run an occasional hotter wash to reset things. Our what temperature to wash towels FAQ covers the trade-offs in detail.
| Situation | Suggested temperature |
|---|---|
| Everyday coloured towels | 40 degrees |
| White towels and a deeper clean | 60 degrees |
| After illness or for heavy soiling | 60 degrees |
| Delicate fibres (bamboo, microfibre) | 30 to 40 degrees |
How much detergent should you use?
Use a moderate amount, generally less than people assume and no more than the detergent's stated dose for your load size and water hardness. Too much detergent is one of the biggest causes of towel problems: the excess cannot rinse out fully and builds up in the terry pile, leaving towels stiff, dull and water-repellent.
Liquid detergent rinses more cleanly than powder for towels. If your towels have become crunchy or smelly despite regular washing, detergent and softener build-up is the likely culprit, and a strip wash will clear it. For ongoing stiffness, see why are my towels hard and how to soften stiff towels.
Should you use fabric softener on towels?
No. Fabric softener is the single worst thing for towels. It works by coating fibres in a thin waxy or oily film, which makes laundry feel soft but seals the cotton so it can no longer soak up water. Over time, towels treated with softener feel slick, dry slowly and absorb poorly. Dryer sheets do the same thing.
To soften towels safely, use white vinegar in the rinse occasionally instead of softener; it cuts detergent residue without coating the fibres. The full explanation is in our fabric softener and towels FAQ, and if your towels have stopped absorbing, see restore absorbency and new towels not absorbing.
How should you dry towels?
Dry towels promptly and fully; a slow or interrupted dry is what causes that musty smell. You can line dry or tumble dry, each with trade-offs.
- Tumble drying on a low-to-medium heat fluffs the pile and gives the softest result. Avoid high heat, which scorches fibres and shortens towel life, and remove towels while just dry rather than baking them. See can you tumble dry towels.
- Line drying is gentle and energy-free but can leave towels stiff, especially in hard water; a short tumble or shake afterwards softens them.
Whatever the method, never leave a damp towel balled up in a machine or basket. If a mildew smell has already set in, our remove mildew smell guide explains how to clear it.
What ruins towels?
Most ruined towels are the victims of a handful of avoidable habits:
- Fabric softener and dryer sheets, which destroy absorbency.
- Too much detergent, which builds up and stiffens the pile.
- Overloading the machine, so towels cannot move, rinse or dry properly.
- High-heat tumble drying, which scorches and weakens fibres.
- Leaving towels damp, which causes mildew and permanent smells.
- Bleach on coloured towels, which damages fibre and colour; for whites, use it sparingly and see how to whiten towels.
Washing new towels before first use also matters, because factory finishes can repel water; see how to wash new towels. All of this sits within our wider towel care guide.
The bottom line
For everyday use, wash towels every three to four uses at 40 degrees with a moderate dose of liquid detergent, no softener, then tumble dry on low to medium. For white towels or after illness, step up to 60 degrees. For delicate bamboo or microfibre, keep to 30 to 40 degrees and low-heat drying. If towels have already gone stiff, smelly or non-absorbent, run a strip wash to reset them, then return to the simple routine above to keep them soft and absorbent.
Frequently asked questions
How often should I actually wash my bath towel?
After every three to four uses, assuming it dries fully on a rail between uses. If your bathroom is humid, the towel stays damp, or it has been used on broken skin or during illness, wash it sooner. Gym and sweat towels should be washed after every single use to prevent bacteria and odour building up.
Why do my towels feel stiff and rough?
Usually because of detergent or fabric softener build-up, hard water, or line drying without fluffing. Softener coats the fibres, and excess detergent cannot rinse out, leaving the pile crunchy. A strip wash clears the residue, white vinegar in the rinse helps, and a low-heat tumble or a good shake restores the soft, fluffy pile.
Can I wash towels with other clothes?
It is better not to. Towels shed lint that clings to other fabrics, and they need hotter water and a different drying time than most clothes. Washing towels together, separate from clothing, gives a cleaner result, lets you choose the right temperature, and protects delicate garments from lint and abrasion.
