Basically you need a Vit C powder, ultrasonic cleanser and lecithin. Plus some water and a blender. You soak the lecithin granules (I used hot water) and dissolve Vit C powder in water (I put a tiny bit of baking soda there as well, to make it less acidic) and then you blend it and finally run it in the UC for up to 30 minutes. Easy and cheap. :)
