citrus salt scrub: 1 cup sea salt, 1/4 cup oil (olive, almond, or coconut), 1/2 tsp lemon juice, 1/2 tsp lemon zest (optional). Mix oil a little at a time with the salt. Add the zest. Drizzle the lemon juice over the mixture, making sure not to get it watery. Store in an airtight container.
This is excellent to use on kitchen cabinets or any wood surface before painting... gives a "tooth" to the surface so paint adheres. Use in well ventilated area, smelly but very effective to prevent paint from chipping.
