Question about Semi white and stain cleaning

I'm fully aware that white skin is a PAIN to deal with once stains come into play, My saber alter unfortunately has a lot of said stains, and after realizing that treating them from their stains results in the vinyl giving off yellowish marks , it basically has put me off from buying any other WS DD.

 

Now lately some SWS DD's have caught my interest, but before I decide to pull the trigger I want to ask SWS owners if de-staining them with benzac hasn't caused the vinyl to react like in white skin's case? I've heard that they work well with the cream, but I'm not completely sure and would want clarification from other SWS owners ^q^

I don't know about other owners, but it was fine on my Miku.
