I have kitchen utensils made of rubber and silicone (as opposed to plastic). Are they like plastic utensils and don’t require special Kashering for Passover?

I also have knives with ceramic blades. Are they like ceramic pots that don’t require special Kashering for Passover?

Finally, I have kitchen utensils made of bamboo or wood (for stir frying). Can they be Kashered for Pesach and, if so, how do I do it?
