I have a small potable steam cleaner I got from my brother for Christmas one year,I'm not sure of the make,I will check and let you know. It came with a variety of snap-in-place brushes,it heats up quickly and gives off great steam! I love it,it loosens birdy doo-doo pretty quickly on the birdies cage bars. I also use it for cleaning the inside of my car and crud on my motorcycle lol.
I use a Mc Cullough Heavy-Duty Steam Cleaner. Its perhaps overkill but it works great for cage cleaning and household cleaning both. I'm really happy with it.
