I have done this to a fridge once...was so filthy and mold and things i could not recognize, so i used a power washer on it, and boy did it sparkle, but had to leave it out in bright sun for 2 days to dry completely out, kept rotating towards the sun, turned out to be an excellent machine, and worked perfect and quiet, if your going to do this I recommend also spraying underneath to clean the coils, just have to let it dry out for a few days....
