I wear woollen jumpers a lot and hand wash them. As I haven't seen Woolite for years, or Stergene (loved the faint smell), I've been using Tesco Wool and Silk detergent, which doesn't have a lingering smell. Then I rinse and spin in the machine and hang them on the line, doubled over with with a peg on each cuff as well as the body so that the sleeves don't stretch. If it's a very, very delicate garment, like a shawl, I would lay it out on a towel on the floor.
As I hate the smell of fabric conditioner I never ever use it.
Now that I know that Woolite still exists, I shall hunt it down. Thank you! (Don't suppose anyone has seen Stergene?)
