Don't you love small glass spice jars? They are refillable and you can see what is inside. They are a PAIN to clean though! Let me show you an easy, quick way to get them tidied up!
Step 1: What you need
You most likely have everything you need already in your kitchen!
A small dirty jar that needs to be cleaned
Warm tap water (not pictured)
Liquid dish soap
This technique is also fantastic for cleaning bud vases or salad dressing cruets as well.
If you do not have plain rice on hand, coarse salt or quinoa may work. I have not tried them for this purpose but they seem small enough and should be abrasive enough to do the trick.
