I keep a lot of used things to re-use them later. I hold onto all sorts of aluminum cans for gardening and office organization, old egg cartons are also used for seeds, bottle caps to make matching/memory games for my little guy and glass jars for various baking/kitchen goods.
Sometimes I find that glass jars keep the smell of what they were originally holding. Even though I wash them, sometimes by hand AND in the dishwasher, they still smell like pickles, salsa, or worse...green olives! (My husband loves green olives!)
So if you are also saving glass jars, here is a little trick to get rid of the smell. Baking Soda!
Clean your jar thoroughly and then put about 1/2 Tablespoon of baking soda in the jar. Put the lid back on and voila! No more smell!
So far my glass jars contain baking powder, salt, candy, brown sugar, chocolate chips and raisins. They all taste like what is currently in the jar and not pickled.
