1. I wash as needed. I just do a standing sponge bath with about a teaspoon of Dawn dish soap in a couple of quarts of warm water. Dab baby oil every 3 to 4 months after bathing. Spot treat stress areas with Vaseline every so often. A light dusting with cornstarch after each bath once she’s thoroughly dry or following a baby oil rub, if it was time for that. It will take several hours for baby oil to absorb before she’s ready for powder/cornstarch.
2. Once every two weeks. I use baby oil and a microfiber washcloth to touch up small areas on my dolls. Every three months. I use a spray bottle load an antibacterial soap and water with a microfiber washcloth to give them a good going over. Then spray them off with as little cold water as I can use then dry them off with a microfiber towel. After each treatment, I’ll powder them.
