i don't do a lot of scale-work, but for chain, i just fill a dish tub with water and a very little amount of soap and dip the piece in and out of the tub for a few minutes. then fill with clean water and dip again (repeat this step if you keep getting more bubbles). i'll then throw it in an old pillow case and put it in the dryer. with anodized scales, you may just want to put it in an old towel and hand tumble it dry so they don't scratch. others may have more experience.
