I am trying to improve the kashrut level in my kitchen. The food itself has been kosher for years as best I know (ingredients, separation of meat and milk), but I didn't always know all the other things I needed to do to get this right. Specifically, tevila.
I have some new dishes now and I want to start off right with them. I've found this page that explains what does and doesn't require tevila, but my question is more basic: what exactly do I do? Do I just show up at the mikvah with my box of dishes? Am I supposed to make an appointment? I know that mikvaot for people are time-restricted; how does that interact with me and my dishes? Is there a customary donation or fee?
Assume I've never done this before: what do I need to know?
(In case you're wondering, knowing that my kashrut is deficient I do use disposable utensils when cooking for other Jews. But I'd prefer that my kashrut just not be deficient in the first place.)
