Can I put jar lids in the dishwasher?

Asked by KatawaGrey (21350 points ) May 9th, 2011

I’ve recently had this idea to decoupage bright bits of paper onto jars to use as containers for odds n’ ends, candles or whatever I feel like. I was going to buy a bunch of jars until I realized that I buy food in jars all the time so it would be easier and cheaper to clean these out, remove the labels and just use them. Well, I’ve discovered that the easiest way to clean out the food, remove the labels and remove the glue from the jars is to just stick them in the dishwasher.

Can I do the same with the jar lids? I feel like I can’t clean them as thoroughly with just a sponge and dish soap so I’m wondering, can I put them in the dishwasher without damaging them?

I’m pretty sure you can for most jar lids. Just be sure to take them out immediately and make sure that they are dry (for metal lids so that they won’t rust, you may have to wipe them dry) and pay careful attention t the rubber gaskets that are usually stuck to the inside part of the lid. If the gaskets get damaged (melted or get cuts or cracks in them) your seals won’t be very good.

@Kardamom: Thank you! For the most part, I’m now worried about the seals too much since I won’t be holding things that need to be kept fresh, but I would want my lids to be intact enough to stay on. :)

Yes, I have washed jar lids and they have had no damage.

I’ve done it. Most are fine, some rust and some lose their seal. Seems to be a trial and error thing… go for it.

I haven’t had any trouble with it.

I wash jar lids in the dishwasher all the time.

Even tho they come out clean, there’s nothing that will get the red stain from spaghetti sauce off of the rubber gasket part. It’s clean but that sauce stain won’t come out no matter what :)

But all other jars should work out fine for your purpose.

I also put a large bowl or colander over the area where I put them to keep them face down and prevent them from ending up all over the place or falling into the bottom spinner blades.

No problem. However, please understand that you can not re-use jar lids for shelf stable caning. The seal on jar lids are designed to slightly melt at canning temperatures to form a seal. They are only designed to seal once.

That being said, I see no reason that they can’t be cleaned in a dishwasher and used for the craft projects you describe.

Yes, you can put them in the dish washer, just make sure they are thoroughly dry or they can form rust spots.

As long as they’re not made of heat sensitive plastic, you should be fine, and like @YoBob said, the hermetic seal will be gone, so don’t try to put jams or other preserves in them.

@AmWiser has a good idea to take them out of the dishwasher right away and dry them well or any exposed tin will rust. Dish washing powder is highly caustic.

I’m going with @ANef_is_Enuf‘s answer. I put jar lids in the dishwasher and some of them seem to rust with repeated dishwasher washings and some of them don’t but if you are cleaning them just once and then using them for dry storage it shouldn’t be a problem, though it might be a good idea if, when the dishwasher cycle ends, you pull the lids out and dry them by hand then let them sit until they are entirely dry.

I’m doing that now with all of my baby food jars. I feed my daughter and then at the end of the day, the baby food jars and lids all go in the washing machine. I use goo gone to get rid of the annoying glue stripe.

I’m making a magnetic spice rack. I like the decoupage idea too, though.

I washed my jar lids and they came out fine.

@keobooks: Keep me apprised of your spice rack and I’ll keep you apprised of my decoupaging!
