Luffa sponges are great for washing items like large pots and other containers. I use them for cleaning almost everything, including cars, boats, plastic buckets, and anything that needs scrubbed but can't withstand steel wool. Non stick cookware is one example. A large loofah or a smaller piece on a handle or rope makes a great back scratcher. They can be cut into many shapes for scrubbing pads, padding, and other craft uses. The loofahs can be cut lengthwise with the core removed to make sheets of sponge material. These sheets of luffa material can be sewn into items like table hot pads, sandals, bath mats, hats, or anything else you can imagine.
