What you describe is pretty normal. If you look at the dishes you make, each one has a countdown to when it will spoil. It varies how long it takes different dishes to spoil. If you make several dishes, one after the other, then they'll usually expire within hours of each other. So, it's not unusual to have to clean out the fridge every day or even several times on the same day. The only way to avoid spoilage is not have leftovers in the fridge. But it you take a look at what is in the fridge and eat those that are near their expiration, then you'll cut down on the spoilage.
Hope this helps.
