A washable pad fails in one of two ways. It stops absorbing, or the backing gives out. Both are caused by how it gets washed, and both are avoidable.
The wash, step by step
Nothing here is fussy. Every step exists because skipping it costs the pad something specific.

1
Shake the solids off outside, then pre-rinse cold
Rinse until the water runs clear. Cold first matters: heat sets a stain into the fibres instead of lifting it out.

Machine wash warm, below 40C
Temperature is the part that matters, not the cycle length. Heat is what degrades the waterproof layer.

3
Use less detergent than you think
Residue builds up inside the absorbent core over months, and a pad that has slowed down is usually carrying soap, not wearing out. Independent care guides for the category all say the same thing.

Skip fabric softener and dryer sheets
They coat the top layer, and that coating is exactly what stops liquid getting through to the core.

Tumble dry low, or hang it
High dryer heat is the single fastest way to ruin the backing.

What actually wears a pad out
Not use. Pads rarely die from being peed on. They die in the laundry.
Heat, from hot washes and hot dryers, breaks down the waterproof backing.
Bleach attacks the same layer.
Softener residue stops the top layer absorbing, so the pad looks fine and stops working.
The anti-slip backing is the part that goes first. Once it starts to split, the pad is finished, and no amount of careful washing brings it back. That's worth knowing before you buy rather than after.
How often to wash it
Independent care guides across the category recommend washing every two to three uses, for bacteria and odour rather than for absorbency.
Those are two different questions, and it's worth being clear about which one a number is answering. How much a pad can hold before it stops absorbing is a capacity figure. How long you should leave it down is a hygiene one. Capacity is not permission.

Both pads from one 2-pack on a drying rail side by side, daylight, one clearly still damp.
Air drying takes hours, not minutes, because the core genuinely holds liquid. That is the whole reason it ships as a 2-pack: one stays down while the other dries.
If it starts to smell
Odour is almost always a timing problem, not a cleaning one.
Wash it soon after use rather than letting it sit. A pad left soaked for days is the one case where smell genuinely lingers.
Add a splash of white vinegar to the rinse. Category guides put this at about a tablespoon for normal use, up to half a cup for stubborn odour.
Skip the softener again. It traps odour in the fibres rather than removing it.

Why the size matters more than you'd expect
A bigger dog doesn't just need a bigger pad because it's bigger. It needs room to turn, sniff and pick a spot before it goes, and it stands wider while it does. Give it too little room and the pad gets missed at the edges rather than soaked in the middle, which reads as a leak when it's really a sizing problem.
Our four sizes and what each one suits are set out on the washable pee pads page, in inches and centimetres.
