Every month or so, I take my cages outside, remove all fleece, etc., and spray with a hose on jet stream setting. If you do it at the right angle, the wodent starts spinning like mad and flinging nasty water everywhere. Repeat until it flings clean water. Dry. Take back inside.
Wow, you must have clean gliders! If I leave a Wodent in my cage for a WEEK, its totally nasty! I have to take it apart!
I always take it apart, handwash the tiny pieces & put all the big pieces in the dishwasher. I don't use the Nail O Matic anymore, but when I had them, I put those in the dishwasher too & just made sure they were dry before using them again.
I like to do it in the dishwasher because then I know its sanitized. With the hose, I can't get hot water, no matter how hard the spray is.
