Maybe it's my OCD or something but I'm stuck..

I use newspaper or paper towel in all my tubs because I like to clean them out once a week - disinfecting and the works, then lay down fresh paper.. But I'd like to switch to cypress or reptibark and obviously (because of $$$) I can't buy a new bag every week for my routine cleaning spree...

So.. Im trying to compromise... Can I still do my weekly disinfecting and then return the same substrate (spot cleaned of course) or is that just ridiculous?

For those of you who use cypress or reptibark, how often do you replace it?

I've tried using aspen and replacing that every week but I hate the stuff, won't even use it for my rats...

Tell me - what are your cleaning routines?
