hello vince and henry!...nice looking birdie he is!...mine had a biting issue upon first receiving him, but has since calmed considerably (after about two weeks for him)...he will still bite on occasion, but nowhere near as often or as hard! ...have patience,he'll come around to you
try some lemon juice in your vinegar water...really helps with 'dried on' poo, and adds a little bit better smell...baking soda works wonders too (i have a small petting zoo in my house, so have been looking into this type of thing as well, lol)...
