To keep cheese fresh you should only leave the cheese out of the refrigerator for up to 2 hours.
If you're not using the cheese within 2 hours then refrigerate it to prevent any problems with the cheese going bad.
I only leave cheese out of the refrigerator if I'm gonna be eating it or using it for cooking within a few minutes and if not I leave it in the refrigerator.
I used to leave cheese out longer until I found some maggots in a block of cheese I left on the counter for 5 hours.
So be aware that if you have flies hanging around your house that the flies could put maggots in your cheese if if left out too long.
