Re: Washing wool in a machine
You don't necessarily have to lanolize every time you wash (I do it, but I hand wash all my wool). As long as you use wool wash (i.e. a soap that won't strip the wool of all it's detergent), then you should be ok. You can use Eucalan in the machine.
The Eucalan won't really replenish the lanolin in the wool, so you will have to relanolize eventually. You can probably use high lanolin wool wash in the machine, too, but it's harder to tell how much you need to use so that everything gets enough lanolin in it...
