I've used this cloth to polish sterling silver jewelry as well as flatware. They're correct in saying that you can use it until it falls apart. Great product and much less mess than polishing paste.
This polishing cloth is the same as the one my silversmithing instructor has us use as a final hand polish on our finished pieces. The rouge infused in the cloth gives pieces a beautiful high shine polish.

I used the yellow side and the maroon side leaked color all over my hand. It took a lot of scrubbing to get it off. I glad I didn't get it on my clothing because it probably would have stained.
works great...my silver sparkles!
