Looking to buy one ... to clean clad and other objects.

Does anyone have one? If so how well does it do on cleaning coins? Would you use it to clean older coins like Wheaties?

Any suggestion on a good one to buy?


If you died today are you prepared for where you will find yourself tomorrow?

I have bought 2 of them over the years and if i am honest they have been the biggest waste of time and money ever,totally useless and these had not been el-cheapo ones either,one was a normal one and the other was from my wife's business that cost a 4 figure sum,they have been sat out in the garage for years gathering dust.Maybe great for gleaming up jewellery etc but for cleaning finds i certainly would never buy another one.Just my opinion of course.

Deus and Nexus MP main everyday detectors

Displays on a Detector are really the equivalent of relying on sub-titles,give me a Analogue machine anyday.

Some of my site specific use machines.

The couple I tried did very little in cleaning coins. Now for clad coins you need a rotary tumbler and for cleaning wheaties I have a vibrating tumbler which take a while, but come out looking natural, or close to it.

Great for cleaning jewelry but coins....... no. A rock tumbler is needed for that and what medium you use in it is pretty much "anything goes" My favorite is sand but rocks right out of my driveway works as well. I have used aquarium gravel to commercial rock tumbler medium which is a bit too aggressive for coins but still works. Just keep an eye on it for "doneness" Be sure to clean your pennies separately or all your silver colored coins will have a copper color.

I tumble found coins a couple times a year and this is how they come out after tumbling 12 hours per batch in a handful of sand, a couple drops of dish washing soap and vinegar.Good enough to take to the bank anyway. I might add that a mist of WD40 will bring the shine back and it helps them slide right through the banks coin counter too.:biggrin:

Bells and whistles are nice, but nothing will substitute for the basic understanding of the hobby.

An ultrasonic cleaner is Not adequate to clean the majority of clad coins that I find. I bought one and even after hours of running my coins were still too dirty and discolored to run thru the coinstar machine. Get a tumbler.

For most of your clad coins, tumbling them works best! I have years experience with ultrasonic machines. Don't use them on copper oxidized coins, as they will pit them. Do use them on silver coins. For iron rusted parts, use full strength vinegar, and run for long periods.

Here is the formula for an ultrasonic cleaner solution I use. As I don't use it on Pearls or Opals but its fine for most jewelry and non copper coins.

1/4 cup Mr clean
1/4 cup liquid ammonia
1/2 cup water

It was recommended to be used hot.

What I do, depending on what I am cleaning, is put the piece in different containers, and just fill the tub in the ultrasonic cleaner with water, preferably distilled water.

Also, do no overlook "Stainless steel shot tumbling." Tumbling is an easy and effective way to polish your finished metal jewelry pieces. You just buy some commercially available stainless steel shot, put it in the tumbler. Add just enough water to cover the top of your shot, add one drop of Dawn dishwater soap, your jewelry and rings and start tumbling. Mix silver only with silver. If you add copper, the silver will stain a copper color.

Below is a video I made on stainless steel shot tumbling...called the "3rd Way To Polish Coins and Jewelry."
