Hi all. New here. We have a budgie and we're making fun things for her to play with/on. We want to make a tree play area for her to climb, chew, and hang toys. I looked up safe tree species and chose crabapple. It's winter here in MN, so no leaves or apples to deal with, but wondering how do I clean and disinfect the tree (it's about 6 feet tall) so it's safe for her? I obviously can't put it in the oven, but I can scrub and wash it in the bathtub/shower. Thanks for all advice!!
