I’ve been using the same bottle of Nature’s Miracle Bird Cage cleaner for 8 years….because I keep refilling with plain water. No difference. Spraying the poops with water and waiting 5 min does the trick for just wiping right off. I take perches, ladders, and washable foot toys in the tub, douse them down. Wipes off easily 5 minutes later with wash rag. No significant elbow grease needed! Have not had a clogged tub drain yet from the poops. We always keep Drano around just in case!
