You don't need to use vinegar full strength, or even soap. Here's a good regime:
Dry brush before shower, or in the shower, use those 'scratchy gloves' or 'scratchy scarf'; no soap is ok, even for garden dirt. But if needed, a good but gentle exfoliant is:
Exfoliant Recipe
In a small container, or the palm of your hand, mix about 1/2 each of pure coconut oil and cornmeal.
For shampoo, a vegan bar soap (I like Lush, but would love a recipe if anybody has one). You can get bar shampoos wrapped in tissue paper, negating purchase of product in plastic container half filled with water that gets trucked for gazillions of miles.
Deoderant Spray Recipe (here's where the vinegar comes in)
1 part vinegar
1 part water
a few dropps essential oil, optional
put in spray bottle
Skin Cream coconut oil, or any best quality food oil, like almond or olive. Keeping an aloe vera plant is ok too, as you can slit the leaf and rub the gel that's inside it, on any area that needs a bit of extra attention.
