This method works great on sterling, silver, gold, costume jewelry metals.. But do be careful if you’re got a lot crystals glued into a setting and limit soaking to no more than 90 seconds – or you might melt the glue. Also, don’t immerse natural pearls in this solution – it’s too caustic. It is however, fine for most gemstones and this homemade jewelry cleaner works wonders on cubic zirconia (CZ stones)! And in case you’re wondering ….it also works fab for cleaning silverware, silver frames or any silver home decor!

i work in precious metals so i have used rubbing alcohol, just put gold or silver in a jar, with the rubbing alcohol and wait overnight. there should be a drastic difference in shine and clarity. it does work for all types of jewelry and precious metals except for pearls and rhodium. definitely do not use this stuff on rhodium. it may cause an explosion, just maybe with rhodium.
I tried this and it worked great for some of my pieces (all are 925 silver from Tiffany) but one of my necklaces actually turned darker. Tried the solution two more times and left it to soak, tried to use a polishing cloth after the solution under running water and no change. So bizarre because it worked like magic on all my other silver. Thoughts?

If the jewelry is very dirty or very tarnished – like silver or gold – then you may need to repeat the process so just add a little more baking soda and more boiling water – but make sure it’s boiling, that’s key!  You can also use a toothbrush to get in all the nooks and crannies of detailed jewelry. Be careful with precious gems, stones and metals.
