Put Epsom salt in your large bowl.
Add baking soda and sea salt together.
Mix everything with your whisk or fork.
Make sure there are no lumps remaining.
This base creates the fizzing action later.
Slowly add citric acid to your mixture.
Stir it in very carefully and gently.
Citric acid makes the salts fizz nicely.
Don't skip this important ingredient at all.
Add your favorite essential oil drops now.
Lavender, eucalyptus, or peppermint work great here.
Mix it in really well throughout.
If you want color, add food coloring.
Use just a few drops at once.
Mix until the color spreads evenly everywhere.
Lightly spray water into the mixture once.
Mix quickly after each tiny spray only.
The mixture should feel like damp sand.
Don't add too much water at once.
Too much moisture starts the fizzing early.
Put your bath salts in glass jars.
Close the lids very tightly right away.
Store them in a cool, dry place.
They last for several months this way.
