- 1 cup hot water (boiled but don’t place the brushes in boiling hot water as it may damage the handle)
- 1 tablespoon baking soda
- 2 drops lemon essential oil
Combine ingredients, and mix the brushes around a glass jar/cup.
If they’re really bad, soak over night, rinse with warm water, pat dry and let them air brush side up in an empty cup. Fresh, clean, soft brushes without the residue.
