People with some experience can certainly do this, but if you haven’t used tpe sex doll at all, it definitely isn’t. Due to toxic fumes, etc., precautions must also be taken. I’m a newbie, so please think twice. I have never experienced this look on a doll before, but I want to know … When you clean the doll’s private area, do you use boiling water?
I remember mentioning in a tutorial that TPE can melt or slightly liquefy at 200 degrees Celsius … if you use boiling water above that temperature to clean private areas and then let it air dry, it may be really fast to heat and Cooling may be the cause of structural cracking.
Once again, you got more experienced sex dolls user suggestions before me, I just made a guess based on what I saw that looks like too dry, which may be caused by high temperature or rapid evaporation and material deterioration . Another thing to note-dishwashing soap (I know you only mentioned “mild soap”, so I’m not sure) and similar soaps tend to be “oil solvents” when mixed with water. This is the main idea used when washing dishes with a lot of grease or oil.
