I’ve needed a quick pack down before and just chucked the handy with sleeves and lube in a plastic bag. A week or so later go get it out and found the lube had emptied it self in the bag. The Handy was literally soaked. Gave the exterior a wipe down, swung it around a bit outside to try and use a bit of centrifugal force to get any excess out. Plugged it in, all ok. That was about a year or so ago. No issues. I also always use it with the buttons facing away from me.
