I haven't used either of them much, but I wiped them down thoroughly with disinfectant wipes. There was slight rust in the battery box, so I removed what I could, but some parts couldn't be removed. Please check the photos. Operation has been confirmed with batteries. It works without any problems. Batteries will be removed before shipping. I cleaned them carefully, but there may be some scratches or slight stains from storage. I hope you will purchase them if you understand this.
