Real silver jewelry which is made of more than 92.5% silver tarnishes in the elements, perCosmopolitan.
But the silver itself is not what reacts, rather the remaining metals in the piece, notesHero Bullion.
Perhaps the tarnish is slightly more significant.

Line a bowl with aluminum foil and softly place your silver jewelry on top.
What happened in that bowl?
Science, of course.

Rub the polish on your pieces then rinse them off in the sink.
Buff the jewelry with a clean cloth and voila!
For starters, know that silver polish is only meant for silver jewelry.

Definitely do not use toothpaste or any other abrasive household product like bleach on your jewelry, either.
Your pieces will reward you with their shimmering beauty!
But cleaning your pieces with soap and water to cleanse them of bacteria can bedone more often.
