glaze smells like pickles

I went on the hunt today for free or close to free 5 gallon buckets to store glaze in.
Apparently dunken donuts will let you dumpster dive for 5 gallon buckets that used to have frosting in them. (most buckets still have frosting in them) Firehouse subs will sell you 5 gallon buckets for a dollar a piece. They say the funds will go to the local firehouse. I got 12 buckets from them and in the car I realized that the buckets reaked of.... PICKLES!!! So... I washed them out again and then proceeded in making glazes. They still smell like pickles.
