Introduction: Clean Peanut Butter Jar for Recycling

Intro:

So, you used up the last of the peanut butter and it is time to recycle the jar. However, there is still a film of peanut butter inside the jar. You don't want to put dirty plastic into the recycling bin and you don't want to just throw it out. The peanut butter is difficult to clean out. Sure you can use a lot of hot soapy water to get it out, but that is just wasting more resources than you are saving by recycling the jar. I humbly present the following solution.

Step 1: Tools Required:

Heavy duty kitchen shears or another cutting implement.

A Ruby. More on this later.

Step 2: Cut Jar

Cut jar in half with shears or other cutting implement. Obviously, be careful not to cut yourself. The middle of the bottom of this jar was pretty thick so I had to cut around it. Don't leave any real sharp or jagged edges.

Step 3: !Caution!

!!WARNING!!

Do not attempt this with glass jar, unless your name is Wang Chi. Even then, you should probably think twice about it.

Step 4: Cleaning

Now it is time to use your Ruby. This is Ruby. If you do not have a Ruby available to you, borrow someone else's. If you cannot borrow a Ruby, consider adopting one from a local shelter.

Step 5: Intermission

Grab yourself a beverage.

Step 6: Cleaning Progress

Dog tongues are very efficient.

(bonus points if you can spot one of my other instructable projects)

Step 7: All Clean

Remove the peanut butter jar from your Ruby before it begins to chew the plastic. Place in recycle bin.

You get clean plastic for recycling and the dog gets a treat. Win-Win.

Props and respect to my ex-wife who came up with this idea.

The be-your-own-Ruby idea: Heat some milk, put the hot milk in the almost empty jar, close the lid & shake it well, enjoy a tasty hot peanut-butter-milk (works well also with marmelade or honey jars).

I've tried the hot water but it didn't really work for me.

Good idea. That would probably be great on a cold winter night.

I love this idea, too! You should make this into an Instructable.

I always do the "fill it with hot water and let it soak in the sink" method, but I do feel bad because almond butter — which is what I usually buy — is really expensive and there's still some usable almond butter in there!

I like how you think Pumuggel!

In what kind of Peanut Butter are you finding Palm Oil?? Or trans-fats? I just checked all the most popular brands and three generic, and didn't find any palm Oil at all. Ruby is adorable! However, I think fzumrk could use a new spatula. Where I live, there are at least 2 more pieces of toast worth of peanut butter in that jar!!

I leave the spatulas on the sink or stove and then Ruby steals and destroys them. :)

I also use the spatula, but I see that a lot of people don't like to use that last part. I take it out with a spatula and put it in a container for cooking or baking. A little PB improves the flavor of Mole Poblano and there are several other recipes besides PB cookies.

It may not be from palm oil, but any hydrogenated oil is a trans-fat and is unhealthy for dogs. And about 2/3 of peanut butters list hydrogenated oil as an ingredient. Particularly the cheaper supermarket brands that tend to come in plastic jars.
