A stiff towel does not feel dirty. It comes out of the machine clean, smells of nothing much, and still has the texture of something pressed flat and left to set. That is not the cotton giving up. Terry towelling goes stiff because it is holding something the rinse should have taken away - and in most Irish homes it is holding two things at once.
A towel is a trap, by design
Nearly everything else in your wash is flat. A towel is thousands of raised loops, which is precisely why it dries you and precisely why it keeps whatever survives the rinse. Anything left behind has far more surface to cling to in terry, so towels tell you first.
The first thing is your water
Uisce Éireann puts it plainly on its own hard water page: "Hard water can also reduce the effectiveness of detergents and soaps, meaning you need to use more." The same page notes hard water is very common in Ireland's drinking supply, is safe to drink, and that Uisce Éireann neither softens it nor recommends softening units.
The chemistry underneath that sentence is what reaches your towels. Hardness is dissolved calcium and magnesium, and those ions go looking for anionic surfactants, the cleaning molecule in almost every detergent sold. They bind and drop out of solution as an insoluble scum, so part of your detergent becomes a deposit instead - and a towel is the best deposit-catcher in the drum.
Roughly two thirds of Ireland sits on limestone bedrock, and limestone produces the hardest water - Galway, Clare, Tipperary, Kilkenny, Offaly, Laois, Meath, Kildare and much of Dublin sit at the harder end. Check your own supply by Eircode on the Uisce Éireann hard water page before you change anything else, and see how hard water affects washing clothes for the full mechanism.
The second thing is what you bought to fix it
Fabric softener works by depositing a thin film on the fibre. That is not a side effect, it is the mechanism. It coats. For the first few washes it feels lovely. Over months the coating builds, the loops mat together underneath it, and the towel ends up both stiffer and worse at absorbing water. Most people respond by using more of it. Towels are the load where softener does the most harm, because absorbency is the entire job.
Before it is a chemistry problem, it is a dosing problem
Hard water means you need to use more. That is a dosing instruction, and most formats cannot follow it. A pod is one fixed size, sealed, so it cannot be sized up for Galway limestone or down for three towels. Hard water is the situation a pod handles worst, and it is most of this country. Pods solved dosing for a soft-water world and kept the plastic. A sheet tears along a perforation instead: half a sheet for a small load, a full sheet and a torn extra piece for heavy towels.
What is not in our sheet, and why we say so
Powders and pods usually carry a builder - zeolite, sodium carbonate, citrates - whose only job is to grab hardness minerals before they reach the surfactant. Our sheet has no builder in it and no water softener. Sodium dodecyl sulfate is 58% of the formula and it is an anionic surfactant, so hard water affects it exactly as it affects everything else. On hard-water chemistry alone, a built powder has a real advantage over us, and we are not going to pretend otherwise.
The builder's fix carries its own cost, though. Zeolite builders are water-insoluble by design, and the industry's own patent literature documents white deposits that adhere to fabric, show more on colours than on white, and interfere with stain removal where they settle. It is worst in cold washes, which is where Irish households have been pushed to save energy. Dark towels washed cold with a built powder are close to the worst case, and one of the four causes of white residue on clothes after washing.
Getting a stiff towel back
- Run them on their own at 60C, no detergent and no softener, with about half a cup of washing soda straight into the drum. It softens the water and lifts old deposits rather than adding to them - here is what laundry soda does, and what it cannot do alone.
- Run a second cycle on plain water, nothing added, to carry the loosened deposits out. Use the extra rinse if there is one.
- Shake each towel out hard before it dries. Wet loops mat together, and shaking separates them while they still can be.
- Dry with movement in it: ten minutes in a tumble dryer, or a line on a windy day. A towel dried perfectly still dries stiff even when spotless.
Keeping them that way
Wash towels on their own and do not pack the drum - a load that cannot move cannot rinse. Stop using softener on them entirely. Size the dose to your water rather than to the packet, tearing extra in the limestone counties. Then run the machine empty on its hottest cycle monthly, to keep limescale out of the parts that would otherwise hand it back.
If you tried sheets before and got residue
That is almost always a loading error. The sheet goes into the empty drum first, before the laundry - never in the detergent drawer, where there is not enough water flow to dissolve it, and never on top of a full load, where it sits dry against the fabric. The guide to where to put laundry detergent covers every format. The other cause is overloading.
On cleaning power: for a set-in mark, wet a corner of the sheet and rub it on the stain before the wash. That beats any pod, for the simple reason that a pod cannot be applied to anything. And since towels sit against skin - our sheets contain 1% fragrance and there is no fragrance-free version. If fragrance is your problem, that is a real limitation of ours.

Common questions
does fabric softener make towels stiff
Yes - over months, softener is one of the main causes, because it works by depositing a thin coating on the fibre, and on terry towelling that coating accumulates in the loops, mats them together and leaves a towel both stiffer and worse at absorbing water.
how do you soften towels without fabric softener
Wash them on their own at 60C with about half a cup of washing soda in the drum and no detergent, run a second plain rinse cycle after it, then shake each towel out hard and dry it with movement - ten minutes in a tumble dryer, or a line with some wind.
does hard water make towels stiff
Yes - hard water is dissolved calcium and magnesium, and those minerals bind to the anionic surfactants in your detergent and drop out of solution as an insoluble scum, which lodges in the raised loops of a towel far more readily than in flat fabric.
how much detergent should i use for towels in hard water
Use more than the packet says and size it to the load rather than guessing: a full towel wash in a limestone county typically wants a whole sheet plus a torn extra piece, and the way to find your own number is to add a little more each time until the stiffness stops returning.
