So, I have this hoops I use daily and I shower with them also, they should be rhodium plated but they started oxidising very fast. I already tried the aluminum foil/baking soda hack, I also tried dipping them in cola but nothing. Using a silver cleaner did something but very little, is there any way I can save these? I really like them and I would hate to throw them away so any advice is very welcome ❤️
Ps. There is no buildup, just ox
