Be careful about joking like that. Some folks have actually cleaned computer keyboards in the dishwasher. You can't really do that with lenses because you'd end up with water spots on the internal elements, but somebody might not realize you're kidding and might actually try it. That would translate to one really expensive cleaning, particularly given that Canon would no doubt disclaim any warranty coverage because of "water damage".
good that i dont live in the USA

Im using my t-shirt to clean the lenses
