Works better than could have expected

If you have silver jewelry, these cloths are an absolute necessity. A couple (at least) years ago I put most of my 100+ pairs of earrings into open plastic bowls and lidless boxes temporarily while we painted and spruced up the bedroom. As it tends to do, life interrupted our plans, and my earrings stayed in the cupboard in the bathroom for for a very long, unplanned length of time. Since silver is my preferred metal, when I finally pulled out all the various containers and started to put them back in the holders, they tarnishing was appalling. Some of the pieces were almost black and I was in tears. I tried some small squares that had been enclosed with a few pairs I had bought over the years. They helped a little, but since none of them was less than several years old, I think they had lost a lot of their cleaning capability. I bought one of these hoping it would do a better, easy job, and OMG! What I had begun to think might take years to do now will be done in a few days. Earrings in silver (mostly), copper, and even a little brass are coming clean beautifully. I also did some favorite bracelets, necklaces, and yes, chains (isn't perfect, but helps a lot), and the results have been amazing. I will be ordering more of these and doing the silver pieces I've been hiding in the buffet for years because I so hate using silver polish next. Then they can go in the china cabinet where they can be admired. Somewhere, that will make Grama very happy!

Great product. Will definitely purchase again

[2016 Edit] I've been using these for years, now. I'm about to order approximately the 20th cloth, give or take a few. I've used them on brass, copper, bronze, nickel-silver, silver, gold, and unidentified alloys. I use it extensively on cloisonné items, and it brings out the luster of the metals around the enamel. I try to use clean portions of the cloth on items with stones, paint, cloisonné, etc., then I polish it a little with the blue portion of the cloth to remove any excess tarnish that may have rubbed off the cloth.

I've used them on museum quality pins and jewelry, musical instruments, tableware, copper pots, Christmas ornaments, and everyday metal objects. I'm not going to tell you that it is effortless, but I've used a lot of cloths, and this one is by far the easiest I've used. I discovered these by accident, thought they were probably junk, tried them, loved them, and they're all I've used since.

Less pressure is better. Give the chemical time to penetrate the tarnish. Once it gets in, the tarnish starts coming off easily. Rather than scrub harder, just keep lightly stroking. You'll figure out the ideal pressure, like Goldilocks: not too little, not too much, but just right. I like laying it out on a table with a small pillow under it, then hold the object and drag it back and forth on the surface. For crevices, double-fold the cloth and use something moderately tapered (letter opener, ballpoint pen, wooden dowel) to lightly twist the cloth into the crevice, but with great care not to let the helper stick penetrate the cloth! Whatever works for you. Just take care not to scratch. The cloth hasn't scratched anything of mine, despite reviews here which say it will, so I just say be careful and take it slow, and you'll surely be happy with the results.

Use nitrile gloves (box of 100 from Walgreens) to keep the tarnish off your fingers. Otherwise, you will get blackened fingertips, but I do not see any way around that; no rag could entrap all the particles while presenting a treated surface to the object, so rather than complain about something that's probably impossible to fix, just wear gloves. Nitrile gloves are comfortable without smelling like latex. (soap works, too, if you prefer bare hands)

I'll probably order about 5 cloths, which will last me about two years (I clean a lot of little things). They keep in their bags. If needed, dampen the cloth a little on the first use. New cloths for jewelry. Slightly used cloths for more utilitarian items. Older blackened cloths for copper pots and pans. At least, that's my order of succession.

[Original review follows]
When cleaning silver, you've got a few choices. Cloth, cream, or liquid dip. The liquid is out of the question for fine silver. It eats it up, changes its color, and leaves pits and other artifacts. Creams may be a lot better; I hear of people using them for fine silver, but it's messy and takes a long time when you've got 50 or 60 items that need cleaning. Cloths are more efficient, in my opinion, but take some work. Therefore, you want one that works quickly. This one did the trick for me, and the fine items I polished with it are still shiny and in mint condition, look great.

This is the best cloth I've used, ever. I've had a number of them, but this one really got the tarnish off quickly without scratches, pits, streaks, or any other artifact that I can see. I'm going to order some more, though I suspect that they work best when fresh. Leaving the bag zipped should preserve them for a while. I just want cloths available when I need them, that will do the job and do it well. I think this is one you can depend on.

I bought this for my silver necklaces cause I had used something in the past from Pagoda at the mall. This works the same. I don't think it'd work well on small pieces but necklaces you just run the cloth up and down the length of the necklace and I used the ENTIRE towel from black soot and oxidation as it came off easily onto the cloth. I would only recommend it for necklaces only or something with large or long surface area. It's supposedly made of 100% cotton and I don't think a real jewelry store uses cotton. Do 5 minutes of research and see. But this worked better then baking soda/ vinegar mix and also better than the tin foil with baking soda and salt mix that works by electrolysis or something. Glad I bought 2 cause one necklace killed the first cloth and not sure if it's washable yet. Pieces of cotton sometimes get caught on the side of the necklace that has diamond cuts because it's not smooth. Which was expected. But this worked better than everything else I tried and I used it on stainless steal watch and bracelet too and it took the dirty spots right off with a bit of elbow action.
