There's a huge difference between cleaning and disinfecting.

Spraying and wiping is cleaning ... soaking with a disinfectant for 15 - 30 minutes is disinfecting.

We clean every single cage, water bowl, and hide box every single week. Each month we rotate through portions of the shop disinfecting so that every 4 - 6 months every single thing in the shop is disinfected at least once (more often for quarantine cages or if a sick animal is found).

I use shop rags too ... I get them cheap enough that I can use 1 rag per box ... when we're done, they are soaked and then washed in hot water, soap, and a heavy amount of bleach.

Hope this helps.
