Cool it in the fridge for a few minutes and wipe off the
dampness. No more humidity in this air. Now a small clean fire
uses up all the oxygen in the airtight glass jar, with your
silverware sealed in it.
Your silverware stays bright and shiny.
This is a nice looking glass jar or box,
A small remotely controlled zippo lighter does the job. sealed
air tight, but no need for a vacuum because the pressure
inside is the same or nearly the same as that outside.

You can buy transparent plastic boxes with an in-built vacuum pump. You just close the box (in this case, with your silverware in it), then pump the handle until you get a decent vacuum. They would work nicely for this application. |

Hydrogen. Flush the box with hydrogen, a strong reducing agent. |
|
| |
There will need to be a top-up mechanism as hydrogen diffuses through most things quite quickly. A small electrolysis unit would work fine. |
|

Or surround your precious silverware with things
which will successfully compete with your silverware
in bonding with Oxygen. For example, lumps of red-hot
iron will be much readier to oxidise than
room-temperature silver. |
|
| |
Powdered metallic Potassium. |
|
| |
Lumps of red-hot potassium must logically be even better. |
|
| |
Argon. Displaces oxygen, non-reactive, doesn't diffuse away. Relatively easy to acquire. |
|
| |
There's your problem, right there. |

Editing in answer to Max in particular but also to all the
others... |

It's occurred to me before to preserve newly-minted coins by covering them in candle wax and then leaving them at the back of a shelf for the rest of my life. |
|
| |
Then, when I'm old and penniless, I can dig them out and melt off the wax. Hopefully they'll still be nice and shiny, making them worth far more than face value to collectors. |
|
| |
So, this shelf with all the coins on ... where might it be, exactly ? |
|
| |
Right behind the pile of half-melted candles. |
|
| |
Aren't dirty old coins worth more than clean old coins?
Whenever somebody posts an old coin or gun to
/r/whatisthisthing, everybody is all "don't clean it!"
because apparently that would destroy the collectibility
value. |

Rubber. This is in regard to consuming O2: rubber is great at that as the double bonds just beg for that O. |
|
| |
Used rubber items that would otherwise be thrown away would be perfect for this application. |
