How do you clean and care for a heavy BBW doll?

The weight is the only real difference. Rolling a curvy doll to wash or dry her is a two-handed job, so lay her on a towel on the bed rather than holding her up. Support the hips and lower back when you move her — that’s where the mass sits — and never drag her by an arm. Otherwise it’s standard TPE/silicone care: mild soap, warm (not hot) water, dry fully before storage, and a light dusting of renewal powder on TPE to keep the skin soft. Storing her lying flat or hung by the head takes the strain off the seams a big body puts on them.
