Kookaburra Wash

The best laundry detergent for merino wool and the like (although it's also perfectly good for non-wool stuff). It smells amazing and is also great for if you're on a long trip and want to do some laundry while traveling—you can take a small bottle of this, put a bit into the sink and fill the basin, and hand-wash things like socks and underwear in it so that you don't have to pack as much as you otherwise would.
