I have merino baselayers I've worn a lot and after several years the ones I wear most tend to go a bit hard. I gentle machine wash with kookaburra wash. It kind of feels like it's partly a result of repeated washing (after many years) but also maybe that they just get kind of ingrained with bits of me (skin/grease) that doesn't get properly washed out. Was wondering whether there's a way of giving them a deep clean that doesn't damage the wool? Maybe soaking in a bicarb solution before washing or something like that.
If they look otherwise clean, I'd guess it's just felting of the fibres at the surface of the fabric; not sure there's anything you can do about that, especially as most baselayers are so fine.
