Your heading suggests you are looking for help in drying the snake gourds......the content of your post is asking about cleaning.
Are you trying to clean your green gourds? If so, a smooth edged knife will work to "green scrape" your gourds.
Otherwise, just leave the gourds outside or in your garage or shed for a few months and they will dry on their own. Then they can be washed and prepared for crafting or whatever.

thankyou Jan, i thought they were dry now, i can hear the seeds, but it's been about 7 weeks since we picked them, maybe they need to dry furthur. beth
