When using any type of butt plug, you will want to use a water-based lube. This allows for easy clean up and only requires warm water and mild soap to clean. The tail part of the butt plug can be a bit trickier. If you can, find a model that detaches for easier cleanup. If you need to clean the tail, again use warm water and a mild soap. Let the tail air dry and, if possible, brush it out, so it keeps its shape.
