Time before watermelon cleanse works?

Just wondering how long it takes for the Watermelon Seed Tea to work on helping cleanse the kidneys. I also tried the Watermelon (seeded variety) drink that is made in the blender..I would rather just eat the watermelon, and seeds as I didn't care for the blender drink. I did make tea from the seeds though..it was very easy.

Anyone here with some experience on the Watermelon cleanse?
