Here is a simple homemade produce wash. You probably have all of the ingredients on hand. You can find a spray bottle at Wal Mart for under a dollar (look in the cleaning aisle-mops, soap, brooms, ect.) or I found a cool looking yellow one at Michaels in the dollar section. I also found it located in the wreath making aisle on the bottom shelf--little odd.
Anyway, here is the link for the wash.
