Tried the cleaner on pennies, dimes, nickels and quarters: does not work. Silver coins: works a little. Gold plated coins – I am actually suspecting that the cleaner dissolves gold (from looking at the residue left on cotton swab). The product is very toxic and started dissolving my fingertips. Overall, I am very disappointed – also because of Amazon’s policy when you cannot return the item because of it being a toxic chemical (or something). I am not recommending this product to common coin collectors.Read more

Let me explain. If you are collecting coins as an investment, never clean them with a solvent/chemical. You can run some warm water on them and lightly brush them with a cotton gloved hand. I bought this to check the dates on some common copper coins that I knew had little to no value. It works pretty well without scratching the coin, but the really REALLY muffed coins will still be difficult to read.Read more
I have to say that I was very skeptical. I have a lot of 1970’s proof sets that I cracked open to grade some otherwise beautiful coins. Many of the silver and clad coins had acquired an unattractive “haze”. MS-70 is flat out amazing. Haze gone instantly. Wear exam gloves and be sure to rinse coins _thoroughly_ after treatment. NGC did not return a single Details grade on 13 coins. I have not tried on gold coins, as I don’t own one.Read more
As a lifelong numismatist, I am constantly looking for ways to keep my coins in pristine condition. I’ve tried every kind of cleaner known to man. Mostly, coins should be kept in their original condition. I have many of those. However, some coins have been buried or abused through the years or neglected. These problem coins need a different kind of help. However, I received three proof coins recently kept in poor condition. One had fingerprints all over the surface. I chalked it up to another bad auction and decided to try this solution. The ’99 San Francisco silver proof improved immensely. Under magnification, MS 70 removed all traces of the fingerprint before it etched into the surface. MS 70 changed the value of the coin by several grades. While the product does not work in all cases, it helps to have every weapon in the arsenal against corrosion. So I changed my rating and my mind. I recommend the product, especially under these circumstance. I stand corrected. I’m including pictures of before and after. As you can see, the coin’s alteration is significant.Read more

This stuff sucks. Do not waste your money. You are probably better off using Acetone. I applied a lot of this to various test coins that had varying dirty surface issues. I suppose it is good for removing dirt, but I had just as good results under a running faucet.Read more

I send a lot of coins to PCGS for grading. I use MS 70 regularly to “properly” clean MS coins. MS70 and a couple of Qtips is all that is needed. I’ve had some coins returned MS-70 as result of using this product. It won’t turn a circulated coin into a gem, but it will bring out the beauty of a quality specimen. Highly recommend.Read more

I’ve used this solution for years to clean brilliant,uncirculated ‘BR UNC’ coins. It doesn’t work as well with any other condition of coins. I’ve been using this product for years but it has undergone a formula change, recently. It is thin, has a different odor, and color is different, and is not quite as effective at making a coin gleam. It use to have the consistency of olive oil. It’s thinner than water now. I still have a nearly full 8 OZ container of the original formula and I have used the old and the new and compared for results. The new formula is about a 6 on a scale of 1-10, the original is a 9 or 10. Too bad they changed the formula. By the way, they won’t admit they changed the new and ‘un’improved product. It will work, TO A LIMITED DEGREE, but don’t expect GREAT results anymore, just “fair.”.Read more

The packing was so-so. It was on its side and had no foil seal, so minor leakage happened. It was also a really big box for the size with some air bladders around it. The product on the other hand works great. Many cleaners on the market leave a residue or clean in some areas but not others. I only use this on coins I’m keeping for myself in albums, and then I will only try to remove debris like resin or roadway tar that has become stuck to the surface. In that, this product excels at loosening and removing the gunk.Read more
