Here are the steps that should work fine. Place corks in a Tupperware bowl large enough to hold about 27 corks. You can add some sulfite to the bowl if you want to. Hold your hand over the corks to keep them submerged under water while you are letting water fill the bowl. Pour water from bowl, and invert bowl over a paper towel letting corks fall onto the paper towel to absorb all excess water.
Place corks back in bowl, and place into microwave.
Microwave on high for about 20 to 30 seconds. Leave corks in the bowl and place near bottling area, use them one at a time to cork your bottles. In our opinion, a home winemakers best investment to corking bottles. These corkers are fast and easy. A winemaker can bottle with one hand and cork with the other at the same time.
