I must be overly sensitive to wool. I’ve tried DIY recipes to soften my wool sweaters but none worked so I thought I would try this. I used it twice by soaking my sweaters and both times I had to take the sweaters off after 5 min of wearing them. Then I tried to use it in the washing machine and that helped a little bit. I guess I’ll keep using that method and hopefully once the whole bottle is gone my sweaters will finally be wearable. I gave it 2 starts because directions on the bottle are clear and it smells nice.
