POLISHING CLOTH DESCRIPTION:
The cloths get dark right away as you start to use them, but they keep working for many months, and even years. At some point, when you are tired of looking at it, get another one, they inexpensive as it gets. You never want to wash the magic fairy dust out of these cloths, just use them! If your fingers get a little funky looking, imagine how my hands look after hours in the studio with polishing wheels spinning day and night! (That is actually an overstatement, but it makes being a jeweler seem more macho to say it out loud!)

NORMAL TARNISH NOTES:
You can get some pretty badly tarnished pieces to come right back to life with a little rubbing, and this is one of the great joys of sterling silver. TIP: For flat designs, lay the cloth on a table edge and hold cloth tight with thumb and index fingers on one hand, and move the piece across the tentioned cloth with the other hand. But on the other hand, do what feels right! Yes, sterling will naturally tone in with oxidation, but getting back to a high shine is not that big of a problem IF you are equipped with a Hand Sewn One of a kind Sean's Celtic Creations Sterling Polishing Cloth! Well... OK.... these are a manufactured item that I have silk screened with my endorsement, since I believe you will be very happy to get all that formerly gorgeous jewelry, now tarnished and sad, out of the jewelry box, and back on your body and into the real world where it belongs! 
Shine on Brothers and Sisters!

HEAVY TARNISH NOTES:
Note that there are types of tarnish that are more difficult to remove, like that which is caused by perspiration and higher acidity in some folks. That more intense "chemically induced" oxidation is harder to polish off with a mere cloth than the "atmopheric tarnish" normally associated with sterling silver jewelry. You can be extra aggressive with polishing cloths and get some results. 

ONE SOLUTION TO CONSIDER
There exists a very fine form of steel wool, graded as "000" grit, hiding on a shelf in the paint department of your local or BigBox hardware store, which will effectively remove "edge, back & chain" tarnish very easily, following up with a polishing cloth can bring back the high shine. This is not the best method to use on the "face" of a design, but for those folks (usually guys) that like a bit of duller satin finish, steel wool of this grit can be used gently on the entire piece.

CHAIN CLEANING
Take care when cleaning chains NOT to pull hard on the ends. Pinch the chain itself instead of the clasp and connections to reduce stress on these parts when cleaning. There are enough people in the world who have broken chains when cleaning them for me to mention this tip...Chains are subject to heavier tarnish due to perspiration. See Heavy Tarnish notes above.

CLEANING DONT'S!
No ultrasonic or dip cleaners please! I work hard to get all the contrast in the lower areas of the patterns, which is the main contrasting element I have as a silversmith artisan. Most of these methods can reduce or make irregular the antiquing I have done during the finishing process.
IF YOU DIPPED YOUR PIECE, AND NEED HELP, LET ME KNOW, DON'T DESPAIR!

RINGS ARE A SPECIAL CASE!
All manner of odd debris can become lodged in the lower engraved portions of the pattern on rings in particular, and on pendants and earrings as well at times. Block the drain on your sink to avoid taking your sink apart, get a soft bristled toothbrush, and gently brush the offending debris (hard hand soap, playdough, bread dough, suntan lotion etc). If you need a little liquid soap, that's ok if needed.
