Period-having peeps, how do you deep clean your period underwear? We've a few different brands and we obviously rinse them out and wash them as soon as we take them off but they don't smell as clean as I would like. Online advice seems to advocate bleach or hydrogen peroxide which seems like it would have a negative impact on the materials. I've seen one suggestion for baking soda, borax and laundry powder which sounds more friendly but am open to other suggestions
