Since my brother split up from his partner he's been turning up a lot with washing to do. I don't mind but I'm bothered by how much b.o. seems ingrained into the armpits of his jumpers and t-shirts (he has a very active job) and I can't seem to wash it out. I've tried scrubbing in the sink before putting them in the washing machine but I can't lose the smell.
Any brilliant tips?
