How do you make homemade Tarn-X for silver or gold?

Wanting to remove tarnish from silver jewelry box but don't have any Tarn-X in my cleaning supplies, just wandering if there is a quick,easy, safe way to remove tarnish without going and buying something, it would be a plus if it was a cheaper than Tarn-X...THANKS!!!

If you use the boiling water, aluminum method, you need to use WASHING SODA, not baking soda. Arm & Hammer makes it. It's used in for laundry. Everyone writes baking soda, that is incorrect.

Baking Soda works good enough for me.

As a specialist in silver restoration, conservation,
and preservation, I have many years of knowledge about chemical dips,
especially Tarn-X. I routinely receive objects for refinishing due to damage
from this horribly destructive product.

Tarn-X works by dissolving the tarnish (and silver!) on an object at an
accelerated rate.

Tarn-X will quickly remove factory-applied patinas (if left in the solution for
more than a few seconds) or gradually (if dipped quickly each time the object
requires cleaning). You'll notice a soft white surface develop over time.

Tarn-X will quickly strip the shine from silver, leaving a dull, lifeless
appearance.

Tarn-X will cause pitting of the object's surface. These surface defects will
act like a sponge and more readily absorb tarnish-producing gases and moisture.
The object will eventually require professional polishing to restore the
original finish.

Tarn-X is made up of acidified thiourea (a known carcinogen). Acids are
corrosive and will damage silver, niello, bronze, stainless steel knife blades,
and organic materials such as wood and ivory.

Tarn-X, when used on objects that have sealed components, such as candlesticks
and trophies with hollow feet, or teapots with hollow handles, may leak into
the cavity through small holes or imperfections in the joints. At this point,
it becomes virtually impossible to wash the chemical out. If you're working on
a baby cup with this type of rim, do you really want an infant drinking from it
after using Tarn-X?

And these are the results from using Tarn-X:

This is how I do it... - line a bowl with alluminum foil - fill the bowl with boiling water - add 2 tablespoons of salt - put the silver into the solution and watch the tarnish disappearing... - rinse carefully! Although this removes the tarnish, to get a good shine on the silver you have to polish it...
Just finished using your formula and I am very happy to inform you that it worked perfectly. I had an American Silver Eagle Bullion that was tarnished - not any longer - It turned out absolutely Brilliant.
Salt, or baking soda works as well. For gold, you can clean it with ammonia, but that doesn't usually bring it up to "high shine", your best bet for either is definitely polishing. Stainless steel, too. A jewelry supply store may have a cloth impregnated with jeweler's rouge, that might be enough to get it a little shinier, but for any more than that, you'll want to take it to a professional polisher. If you have a lathe, you could always polish it yourself, though that can get tricky depending on what it is.

I wouldn't ever put silver in boiling water. It will eventually loosen knife handles and damage it because water gets inside and corrodes it. The only silver cleaner we use in my restaurant is Silvermate liquid silver cleaner. Its 96% water, very mild, and cleans and polishes in less than 30 seconds. You don't have to scrub the tarnish off at all and scrubbing it what wears the silver plate off your utensils. If you want to, check them out: www.silvermatecompany.com
A safe method of cleaning solid silver, (or silver plated items without removing the silver), is to use a chemical dip. Completely line, or lay, aluminium foil in a GLASS, CERAMIC, or PLASTIC bowl and place the item(s) to be cleaned on it, ensuring that the silver is in contact with the aluminium foil. N.B. DO NOT USE A METAL SAUCEPAN ! Wearing protective gloves, dissolve half a cup of sodium carbonate (washing soda) in two pints of very hot water and pour it over the item(s). The solution will bubble as the corrosion is transferred chemically from the object(s) to the aluminium foil. After a few minutes, remove the object(s) from the solution using plastic or wooden tongs or spoon, and rinse item(s) under hot water, dry and burnish immediately. If, for example, cleaning a single, small item of jewellery like a ring, don't drown it with 2pints of solution, just scale it down to a small bowl or cup, and a heaped teaspoon or a dessert spoon of sodium carbonate. As long as the water is very hot and solution is bubbling away, you'll know it's doing its job! Cool ! It really does work a treat ! This same dip method can also be used for copper and brass, but do not clean different metals in the same dip and never dip inlaid or enamelled pieces.
