Please do not use the "hand wash" setting on the machine as this is not the same thing as a genuine hand wash. Please lay flat to dry, do not machine launder or dry. We recommend using a fitted washable mattress protector over top of any wool puddle pad so that the puddle pad will not require laundering as frequently. Using a high-quality specialty detergent with lanolin content such as Eucalan Fine Fabric Wash is a great way to maintain woollen items. The natural lanolin content found in Eucalan will help condition the wool fibres to ensure optimal humidity regulation.
