Tell us about yourself!
One time when I was travelling, I was running out of clean underwear and needed to rinse some out in a hotel sink. Hand soap leaves a hard to get out residue and they didn't smell as fresh. I used toothpaste. It worked. Easy to rinse out and clean smell.
I seal the egg and put a coat of glaze on it. Then I use an ordinary dremel with the smallest cut off blade that I get at the Golden Egg of Idaho. You can look at their website. I have cut many chicken eggs this way.
