When I first noticed rust spots appearing on one of my favorite sets of silverware, I thought I was doomed. Or that my expensive silverware might actually be cheap. Either way, I wasn't keen on replacing them.

And then I remembered the rust eraser the vendor had given me the last time I had my knives sharpened. I'd accepted this unlikely-looking nugget of gritty rubber with thanks and promptly forgotten it in my junk drawer.

Would it work on my silverware?

I am now convinced that everyone needs one of these magical rust erasers in their kitchen tool kit. The eraser worked like a charm, burnishing out the rust spots with hardly any effort on my part. Once I washed and dried the silverware, I couldn't even tell where the rust had been.

Rust erasers are made of a rubber compound mixed with a mild abrasive material. They work by scouring away the rust to reveal the shiny metal beneath. They're much softer than sandpaper, and I didn't notice any scratches on my silverware. It just took away the rust and was done!

The erasers gradually wear down with use, but one will last you several years. Besides silverware, these work on chef's knives, cast iron, sink faucets, and other metal kitchen utensils. It works best if there are only a few spots of rust; if it's completely covered with rust, check with a hardware store on the best way to proceed.

You can find these erasers at almost any hardware store for just a few dollars. You can also get them off Amazon (a packet or two are great for bumping up your order to get free shipping!).
