How to Get Rid of Hard Deodorant Under a Shirt Sleeve

When your shirt rubs against your skin, your deodorant oftentimes will stick to the fabric. If you have to apply deodorant again later in the day, the antiperspirant builds up under the shirt sleeve. After the deodorant dries, it remains hard and crusty. Ignoring a deodorant stain can make it difficult to remove later, especially if you wash and dry the shirt without treating the stain first. Remove the hard deodorant stain as soon as possible to prevent it from becoming a permanent addition to your shirt.
