My question: #44368 – just answered; you could only Kasher metal or glass item’s bought. So what am I supposed to do with the wood, plastic or ceramic utensils bought? How do those get kashered?
There is no need to do anything in regard to toveling them. The reason is because the torah only commanded us to tovel metal, (and the Rabbis added glass, because it has certain similarities to metal), and we weren’t commanded to do it to any other type of material. So then go ahead and enjoy. If the utensils were used by the gentile (bought second hand) then they would need to be kashered, which is a very different process of purging out any absorbed non kosher food from the utensils.
