I have been sterilizing my Advent Bottles parts with the Microwave Sterilizer. I got a new Playtex Ventaire bottle today and I read the instruction, and it said the nipple should not be put in the steaming sterilizer. if I just wash the nipple in soap water but not sterilizing it, I feel that it's not "clean" enough. Does anyone know if I can put the Playtex nipples in the sterilizer? Would it destroy the parts?

Thanks in advance,
