Hey peeps, I recently purchased a 148cm irokebijin in S-TPE and have been enjoying her recently. She has picked up some grime here and there. I attempted to shower her and could NOT get her clean enough for my liking. I used hand soap, body wash, mineral oil ( this sorta worked but I could not get it to run off her body and she ended up getting dirtier in new places.) Is there anyway to get her looking factory fresh, or am I just gonna have to keep cleaning her in vain? 90% of posts I search say warm water and soap is enough but is it?
