Particular attention should be paid to the electrochemical corrosion of the silicone material—when salt adheres to the surface, it creates a galvanic cell effect, accelerating material aging. The solution includes weekly cleaning with deionized water and applying a single-molecule anti-corrosion coating to the surface. While these maintenance procedures of the fat sex doll are tedious, they can extend the product’s lifespan by 2-3 times.
