Here are a few tips that might make the job a little easier
Tip 1 Remove bird from cage to fun play area with lots of things to keep him occupied before beginning. Some birds do not like anyone messing with their stuff. If your bird is not tame, or is fully flighted and may get into trouble if left unattended, place your bird in a carrier or small travel cage with fun stuff while you clean.
Tip 2 - Remove all bird toys and perches from cage prior to cleaning. Good time to inspect all toys for wear and tear and throw out anything that might not still be safe. Check bells, texture toys, bird beds, and links closely.
Tip 4 - If your cage is easy to move, roll outside and make great use of a sprayer hose to clean. If your cage is small enough to fit into the shower or bathtub, you may prefer cleaning indoors. (DO NOT LEAVE BIRD IN CAGE IN SHOWER - drowning can happen)
Cages can be washed with vinegar and water, or a mixture of gentle dish detergent and water. Always rinse well after cleaning. NatureChest.com carries several different products specifically made to clean and are bird safe.
NEVER use cleaners such as Mr. Clean, Lysol, Soft Scrub, Windex, 409, etc. to clean anything your bird can come in contact with, as almost all household cleaners can be deadly to your bird. Bleach is not recommended for cleaning as it is toxic if inhaled by your bird, is very caustic to cage finishes, and can burn skin if splashed accidentally.
Tip 5 - Once everything is nice and clean, add a few new toys before returning your bird, because he or she is going to know you have been messing with their stuff, and new toys may help soothe things over for you.
