So, Google tells me that the black marks on my clothes near my armpit are probably caused by deodorant with aluminium in it. And white marks on clothes are caused by deodorant too.
Does the Holy Grail of deoderant exist: one with no aluminium, which doesn't cause white marks? Do you use such a deodorant? I'm not very very sweaty, so don't necessarily need the most powerful deodorant, just fed up with white and/ or black marks in my clothes!
Any recommendations?
