How to Care for a Lambswool Hot Water Bottle

Quick answer

To keep your lambswool hot water bottle in great shape, hand-wash the cover in cool water with a gentle wool detergent, air-dry flat away from heat, and always remove the rubber insert before cleaning.

Step-by-step care instructions

1. Remove the rubber insert before cleaning: Always take the rubber insert out of the lambswool cover before washing either part. This prevents the cover from stretching or trapping moisture inside. Never wash the cover with the insert inside.
2. Hand-wash the cover in cool water: Fill a basin with cool water and add a small amount of wool-specific detergent. Submerge the cover and gently swish it without rubbing or twisting. Rinse thoroughly in cool water until no soap remains. Hot water and agitation cause lambswool to felt. Always use cool water.
3. Dry the cover flat, away from heat: Gently squeeze out excess water without wringing. Lay the cover flat on a clean towel, reshape it, and let it air-dry away from radiators, direct sunlight, and tumble dryers. Heat shrinks lambswool. Drying flat preserves its shape and softness.
4. Rinse and dry the rubber insert separately: Rinse the inside of the rubber insert with cool water and a drop of mild soap. Rinse again, then hang it upside down to dry completely before storing. Do not submerge the insert or use harsh chemicals. Moisture trapped inside the rubber can lead to mould or odour.
5. Store both parts loosely and dry: Once both cover and insert are fully dry, place the insert back inside the cover. Store the hot water bottle in a cool, dry place away from direct heat or pressure. Avoid folding the rubber insert tightly. Storing while damp or under weight can cause permanent damage.
