I loved seeing the responses to my "new" clean hoops. I got so behind in cleaning my hoops thanks to moving our home twice in 2 years and the orthopedic issues and vertigo. I am trying to get away from using a lot of chemicals (505 isn't a chemical, right) so was happy to have dishwashing detergent, hot water and vinegar do such a good job after all of the time and the accumulation. I realized we have a lot of folks new to embroidery and thought they might not even know we need to keep our hoops in clean and working order. So Kudos and flowers to all who responded with their helpful hints
