1. I use Lysol wipes after my silicone doll dries. I give her a good powdering and she’s good to go. Been doing this for 4 years with no ill effects. I clean her full body every 2 or 3 months. Spot clean as needed.
2. Sponge and warm water is pretty much all it takes. You can use a little soap in the water and clean her in bed no problem if you put her on some towels.
