The Extase La Métropole is, as mentioned before, plastic and aluminum, making it safe with any oil, water or silicone based lubricant you desire. It is not water-proof, but is splash-proof, making cleaning a little easier than with some other designs. There is actually a small rubber protection ring attached where the battery compartment closes. I usually use wipes when cleaning this toy just to be on the safe side, but you may want to take caution with the bottom of the toy where the LED lighted control button is. Otherwise, I think you will be fine when cleaning. So, there are some precautions to take when cleaning, but this is not a high-maintenance toy by any means. This also can be stored in the box it came in (which is very sturdy), or in the satin pouch that is included at the bottom of the box. Either way, I claim this to require cautious cleaning, but easy to store.
