Presto! This works like MAGIC! I’m a jewelry-maker, and sometimes generous friends bestow me with old costume jewelry that I love to take apart and repurpose. I received just such a lot the other day, but the pieces I was interested in were dull and discolored and tarnished. Since I didn’t pay anything for them, and since they were useless to me in their present condition, I figured I’d try this.
You can’t use anything else instead of baking soda. None of the other ingredients are necessary either… It’s specifically the vinegar (acetic acid) and the baking soda (sodium bicarbonate) that react and cause the reaction and hence the bubbles. The water actually inactivates both significantly and the salt (sodium chloride) is totally inert in the presence of the acid and base. As a matter of fact, when you combine the acetic acid and sodium bicarb, you get water and salt. The foil also does nothing…you can use any dish.
I just went on your site this morning because I had a lot of jewellery to cleaned. I found that all glitter like gold. The other things are glittering as well. I always used the commercial brand but it ruined quite a few things.I Used all the things that were called for and it worked out fine. If you have a high piece I just put it in a smaller container.
