Firstly, avoid harsh scratching
 
The caring is as simple as trying to avoid harsh scratching. Other Possible problems apart from harsh scratching seem to be very minimal as stainless steel doesn't leave a stain, tarnish, and discolor. Stainless steel ring resists oxidation, rust, and corrosion, they will not bend or break, besides, it also doesn't scratch that easily, so avoid putting your stainless steel ring in your pocket without a jewelry bag or a sealed plastic bag. For stainless steel earrings, simply avoid putting the two earrings in the same bag as it may scratch each other.
 
Secondly, cleaning
 
Cleaning is simple, there are few tips when clean it.
Always clean your stainless steel jewelry lengthwise, and not in a circular motion.
Clean with warm soapy water and very gently. Use a soft cloth such as 100% cotton and gently wipe it. In case of brushed stainless steel, move your cloth along the grain of your stainless steel jewelry with shiny spots. You shouldn't soak you stainless steel jewelry in water.
For dirtier pieces, just use 'plain' white non-silica toothpaste and soft cloth. And again, follow the grain of your piece.
 
Thirdly, storage
 
Although stainless steel jewelry doesn't tarnish, it's always best to store it in a sealed container for utmost protection.
