Aside from cleaning out the fridge regularly, toss out anything that has not been used over a couple of days unless it is condiments. If too many things pile up, it will take you a lot longer to clean up the mess. Using refrigerator filters or baking soda boxes will also help you keep out the odors. Pay special attention that there are no spills that might have dried up.
A quick clean of your fridge should not take a long time if you have been keeping up with your deep fridge cleaning. Check your owner's manual to see suggested cleaning instructions. If the refrigerator shelves are removable, you may not need to turn off the fridge. However, if they are not, to save the energy bill from racking up for keeping the fridge door open, turning it off will be the best thing to do.
