Washable incontinence underwear and pads are practical, cost-effective, and a good deal kinder to the planet than disposables. In most cases they die earlier than they should, and it is almost always down to how they are washed. Fabric softener is the single most common cause of premature absorbency failure. So before anything else, understand what the product is actually made of and what it needs.
How washable products work
Most washable incontinence products use a three-layer build: a wicking layer that pulls moisture away from your skin, an absorbent core that holds the fluid, and a waterproof outer layer that stops it reaching your clothes. Each layer does a job, and each can be wrecked by the wrong wash.
The wicking layer depends on specific fibre structures to move moisture against gravity. Fabric softener coats those fibres with a conditioning agent that lowers surface tension, which is exactly the mechanism wicking relies on. One wash with softener measurably reduces wicking. Keep using it and you progressively, permanently destroy it.
Washing: what to do and what not to do
- Never use fabric softener of any kind, and that includes in-drum conditioner beads.
- Use an antibacterial laundry detergent, which is better than a standard one at killing the bacteria a cooler wash can leave behind, at the temperature your manufacturer recommends (typically 40 degrees Celsius).
- Rinse the product under cold water before it goes in the wash, to stop urine setting into the fibres.
- Wash them inside a mesh laundry (delicates) bag. It stops the products snagging, stretching, or catching on zips and fastenings, and keeps the set together in the drum.
- Do not exceed the maximum recommended temperature. High heat can peel the waterproof layer apart (delaminate it).
- Do not tumble dry above the manufacturer's stated maximum, if they give one. Many products should not be tumbled at all.
- Air dry where you can. It is gentler and it extends product life significantly.
Rotation and how many you need
Keep a minimum of three to five products per day in rotation, so each one can be washed and fully dried between uses. Wearing a product before it is properly dry encourages bacterial growth in the fabric and shortens its life. The practical target is a rotation that gives each product 24 hours of drying time between uses.
When to replace a washable product
- Absorbency has noticeably dropped: moisture reaches your skin faster than it did when new.
- Odour lingers even after you have washed it correctly.
- The wicking layer no longer pulls moisture off the skin surface.
- Any physical damage to the waterproof outer layer.
Most quality washable products are rated for 200 to 300 washes with correct care. Use fabric softener and that can collapse to 20 to 30 washes before performance falls off a cliff. The maths makes the case on its own.
