Don't use soap!!! Use vinegar and water really really hot boiling water. Get a large trash bag and put the tray or aquarium inside and shake it all inside. Replace the cedar shaving, water and food containers should be cleaned in the same way. Make sure your hamster has something to chew on. Did you know that their teeth keep growing, unless they knawl them down. Also, if he or she has a nest, make sure there are no babies inside it before the trash bag. I had a surprise of 5 hamster babies. Good luck.
Use a hand brush and dust pan and dump the soiled bedding into a garbage bag. Remove food dishes, water bottles, houses,toys, and your pet before cleaning the bedding out. Then use a mixture of vinegar and water to spray and wipe down the cage. Place down fresh bedding. Add in toys, food, water, houses, and of course, your pet :)
