I did laundry by hand and I learned that my baby's wool onesies get cleaner this way than in the washing machine with wool program.
At home we only use lin oil soap, here's the link of the one we actually use, which is produced in Sweden:

There are two items "missing" from the folded piles because i wanted to dress both me and baby with some warm wool. Balancing this lack: even though I only washed one sock by hand, there are two lilac socks in the last picture! This is because the other sock had being waiting for months to find back its old companion which had been missed under couch. Now they found their place together again and thy can share their different washing adventures.
