I am getting a used bird cage today from craigslist. I would like to know the best thing to use to clean it. I found this online and was wondering if this is good or if there is something better. Thanks in advance! What You Will Need: 1 clean, empty spray bottle 3 cups hot water 3 tbsp Baking Soda 2 tbsp pure Lemon Juice Lemon juice may not seem like an attractive ingredient to all bird owners, but is completely safe for birds and contains natural enzymes that act as a disinfectant to kill bacteria and help break down organic material. It can be purchased at just about any grocery store, or you can juice your own lemons to make your cleaner extra fresh.
