This may have been mentioned earlier. I don't have time to read this
whole string. When I see people grate orange and lemon peel, I get
concerned if the peel looks perfect. These perfect looking fruits are
usually sprayed with coal tar (cancer causing) dyes. They are used
legally here because it's assumed that no one eats the skins of citrus
fruits.

This is why a rational person scrubs their citrus with steel wool,
then thoroughly washs then, and finally wipes them clean with alcohol.
