• 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.

  • nah I think it's ingrained "me"... I mean they've been washed, and they're clean-ish, but they just never get a very vigorous wash, and the rougher they get the more they pick up skin cells and stuff.
    reading up, bicarb might start to eat at the wool protein, but vinegar is suggested.
