Never used egg white but I have used gelitine.
I find that I very rarley have to clear it. I usually leave it somewhere cool for a week after fermentation, a concrete floor is a good place as it acts as a heat sink, dropping the temp and any yeast with it. If you try to clear to early I probably wont as if the yeast is still active then they are surrounded in co2 making them buoyant. Even if fermentation seems to have stopped yeast is still active for a few days after metabolising by products of fermentation. :thumb:
