How can you keep homemade bath salts from hardening I use 4 parts epsom to one part baking soda with some essential oils added in....they seem get rock hard even tight jar tops?

To prevent your homemade bath salts from hardening, you can try the following tips:

1. Reduce the amount of baking soda: Baking soda can contribute to the hardening of bath salts. Try reducing the amount of baking soda you use to about 1/4 part baking soda to 4 parts Epsom salt.

2. Add a moisture-absorbing agent: You can add a small amount of a moisture-absorbing agent, such as cornstarch or arrowroot powder, to your bath salts. This will help prevent them from clumping and hardening.

3. Store in an airtight container: Make sure to store your bath salts in an airtight container to prevent moisture from entering and causing them to harden.

4. Keep in a cool, dry place: Store your bath salts in a cool, dry place, away from direct sunlight and heat sources.

5. Add a little bit of oil: Adding a small amount of oil, such as coconut oil or jojoba oil, can help to keep the bath salts soft and prevent them from hardening.

6. Use fresh ingredients: Make sure to use fresh ingredients when making your bath salts, as old ingredients may be more prone to hardening.

By following these tips, you can help keep your homemade bath salts from hardening and enjoy them for a relaxing and luxurious bath experience.
