Rusty canning rings - ? reuseable

Posted by Han123 none (My Page) on

So, my canning rings have got specks of what I suspect are rust on them. I thought I had put them away dry, but obviously not dry enough.

Question: As the rings don't actually touch the product, and its a new sealing lid (obviously :) ), can I use my old rings, or do I need to get a whole new set.

As long as they aren't rusty around the lid part they should be OK.

If you have something like a Brillo or Scotchbrite pad clean them up and coat them with some veggie oil.

RE: Rusty canning rings - ? reuseable

They will rust in time, I've used them until they feel like they are not holding well.

Just the moisture in the air will allow them to rust, no matter how 'dry' you get them.

RE: Rusty canning rings - ? reuseable

Agree. I use them until I feel like I'm scratching the jar while screwing them on.

After that they get recycled or turned into some craft project!

I've pretty much decided the protective coating on the rings just won't stand up to automatic dishwasher detergent, so I hand wash all my rings now.

RE: Rusty canning rings - ? reuseable

Thanks for all the advice. Also the point about dishwasher soap, that could explain a lot!

RE: Rusty canning rings - ? reuseable

dishwasher detergent is much harsher than regular dish soap. Even with only hand washing, the rings will rust eventually, but usually after 5-10 years, depending on your humidity levels.

RE: Rusty canning rings - ? reuseable

I agree, hand wash only, but then air dry thoroughly and store in zip top bags.
