Actually to properly disinfect you need a 1:10 (10%) bleach solution. That's the CDC recommendation so that's what I've always gone with just to be safe. Remember when working with strong bleach mixes you need to wear gloves and protect your eyes from splashes. Repeated rinsing with fresh clear water is required afterwards of course.

When I'm disinfecting I fill the container full with the 10% solution and let it sit at least one hour, then scrub every inch, then start fresh water rinses. Then I usually set the enclosure aside, leave it for 24 hours, then re-rinse in clear water. Then I wipe it dry with clean paper towels. I'm very anal about making sure when it's clean....it's clean!
