Some producers do not peel the garlic, which may have mites or other insects. Therefore one should rinse the sour pickles if the processor doesn't peel the garlic. The Aida Yerushlaim insists that all of their garlic is peeled. CRC Hisachdus allows unpeeled garlic.
Flaum's is starting to use peeled garlic for their sour pickles, even though CRC Hisachdus doesn't require it. CRC ah!.... only the "litvish" eat sour pickles so who cares about them.
