Cleaning a Drinkwell pet fountain is easy, but there are some areas that can't be reached with a sponge. The Drinkwell Cleaning Kit includes new and improved features such as a plastic molded handle, a flared sponge tip for deep cleaning, and a vinyl wrap to protect the wire shaft from rust. Works with all Drinkwell fountains. Keeps the Drinkwell fountain running smoothly and providing your pet with delicious, healthy water.
