Uv sterilizer can’t be used with latex, rubber or silicone?

Many websites state that uv rays deteriorate latex, rubber and silicone turning them yellow fast -Is this true? Most pump parts and baby bottles and bottle teats are made from these materials... does this mean we have to replace the pump part and bottles very quickly?

I read in my sterilizer manual that it's fine to use the silicone parts even when they turn yellow. It's not an indication of deterioration. If you UV them every time after wash, it will start to turn yellow by the 2nd week. So I change them according to wear and tear or the schedule recommended by the manufacturer. Some rubber/latex parts cannot be sterilized with UV sterilizer bcos it will harden. Can only boil or steam.
