I got glass containers with plastic lids because I figure the lid rarely contacts the food, and I always take it off to microwave... although now that I'm thinking about it, I usually put that plastic splatter guard thing over the container in the microwave which probably isn't much better.

Used to do the same. Thankfully there are glass splatter guards out there, some of them with plastic handles on the outside. More expensive than you would hope though, I suppose because it's such a niche use, but it's not as if you're going to be buying many glass microwave covers in one's lifetime!

I put a paper towel on food in the microwave to stop splatter. As a bonus, I've found a moist paper towel helps when microwaving leftovers that got dehydrated in the fridge.

I usually put a saucer or plate over the top!
