I wear white cotton/poly shirts to work as part of my uniform. They eventually get yellow stains under the arm and I either replace them or use Soft Scrub to get them out. Well, lately the yellow stains have tiny brown speckles in them, almost like dirt, and I just pulled one out of the wash and the brown spots have multiplied. Super gross.
What could this be? A reaction between my deodorant and the detergent? I recently switched to homemade laundry soap (after the spots started), and I am using the same deodorant that I've been using for years.
And more importantly, what do I do to get rid of it? I'm going to get new deodorant tonight and see if that helps.
