Try adding salts and other chlorine or halogen-containing compounds.
I will add a bit of salt, right now. Thank you. Iām not sure I can add Clorox with salt, so I will not do that, yet.
Try chlorine. Pool chemical stuff should work.
OK. Sooner or later, I will proove these pins rust. However for as long as the are taking to rust, I could probably be able to trust their longevity in a cross stitch over time.
