I’ve been a follower for sometime but I never really utilized some of the key cleaning ingredients you tend to recommend. Today I inherited a beautiful swiss army watch but it had years of caked on grossness. I did an initial wipe down with some soap and water and then I laid it in a shallow dish covered it completely with baking soda and poured vinegar over it. I made a watch bomb! I let it do its thing and then rinsed. The watch looks brand new! Thanks UFYH! Vinegar and baking soda rocks!
