Here is an up close picture of the size bar I used its a .6 oz bar
Drop one soap into each jar
Fill with some warm water
Put the tops back on
Here is a closer pic
Flip them upside down after you have shook them all, i have slacked a little and let my collection stack up
Here is one about 6 hours old
The bar stuck to the top
Now let your jars set for a day or even just forget about them for a week when you open them rinse them with hot water and the smell should be gone.
Now what ever food you put in the jars will not have an odor from the jar top.
This here is a very large jar that used to be a pickle jar I got from Costco I used about 5 different smelling soaps and water in this jar and let it sit for a week now I keep smelly free sugar in it.
