Everything can be cleaned and sanitized. But the plastic stuff should probably be kept separate, simply because it's not worth the cost to have any issues.
Anything metal can be heated in oven to sterilize, or soaked in bleach solution. (except I think you're not supposed to soak Stainless in bleach). But a good cleaning and sanitizing ought to fix most anything that can't go into the oven
If your takin' your girlfriend out tonight
You better park the car well out of sight
'Cos if they catch you in the back seat trying to pick her locks
They're gonna send you back to mother in a cardboard box !
