Summarize the following:
Moisten your skin first with warm water. Then massage 1 to 2 tbsp (14 to 28 g) of bath salts into your skin to sooth and exfoliate it.  You can also sprinkle aromatherapy bath salts onto the floor of your shower. This will exfoliate your feet while infusing the steam with fragrance. Try using bath salts as a foot exfoliant in combination with a foot soak. Whether you’re packaging up your homemade bath salts as a gift or storing them for your own use, store them in a lidded jar or tub. Make sure the container is made of a non-porous material such as glass or PET plastic to keep the essential oils fresh and fragrant.  The container should be closed tightly while the bath salts aren’t in use. If stored properly and kept dry, aromatherapy bath salts should last for many years as they don’t contain ingredients that will go bad.

Summary:
Use a handful of bath salts to exfoliate moistened skin in the shower. Store aromatherapy bath salts in an airtight, non-porous container.
