How often do you clean out your fridge? And I mean take everything out, clean out the inside, wash the drawers, shelves etc.
I generally wait until it gets pretty filthy before a full, deep cleaning. I do go through weekly and clean out old stuff, throw away leftovers that didn't get eaten, expired stuff etc. And I do try to clean up spills as they happen, but over time it still gets filthy. I just recently did a deep clean on it.
I'm the same as you. I say maybe.. once a year unless there's a big spill or mess, or if the power has gone out for a significant period of time. I get in the mood to do that kind of stuff in the spring, those first couple of weeks where we can open the windows and let things air out after the long winter. Being in Texas though, you might not get that drastic temperature change! That time of year inspires me to do A LOT of cleaning.
Our drastic temperature changes in June, when it turns 100 degrees outside! But spring still inspires me to do cleaning. Winter is mildly cold and usually rain in my region of Texas...so Spring is always welcomed.
Anyways to answer your question. I'm going to say, once every 2 years. Usually when we move out of a place....we've been moving every 2 years for the past 6 years and yep we are gross, we never clean our fridge THAT good. About every other week I do a food check to make sure nothing is going bad. I occasionally wipe surfaces around the food...but I never take out shelves.
When I was freelancing for an interior designer and worked inside her home, which was also her office, she made me clean her fridge once. I've never seen more food packed in a fridge in my life. To put everything back so that it fit, was like doing a puzzle. Ha! We only buy food one week at a time and plan our meals very carefully so our fridge is not usually completely full. Usually on Friday its completely empty besides codiments, cheese, milk and bread.
Oh man, I'm SO bad for this. I'm not even sure I do it once a year. If/when it gets a bit empty, I'll often clean a shelf or two that are easy. Last weekend my mom stayed here while we were camping and she cleaned our fridge for us!!!! SO awesome!
