Hello - I would run this under the hottest water you have from the tap, then when it seems the wax and/or other stuff is coming off, use a soft toothbrush on the hard bits. Give this a few minutes - the hot water will work if you give it time. If you have scalded your hands in the meantime, put the sharpener in a small bowl with really hot tap water, let sit, brush gently with a soft toothbrush, rinse as best you can under hot water. A bit of dish soap might cut the wax/oil in the product. The hot water will dry quickly with a shake.

I'm a bit of a fanatic about cleaning the blades each time i use the sharpener. I remove the top and bottom, then wipe each blade with a tissue. I use the included attached pick to clean out the corners as much as possible, then I use q-tips for the final sweep. I've had my sharpener for years and have never had an eye infection.
