What are some safer products to use to degrease birds? For over 40 years, I have washed my bird skins in Dawn and then degreased them with gas, odorless mineral spirits, or camp fuel. I am starting to have some health problems related to breathing in petroleum products. I work in a well-ventilated area, and I use nitrile gloves, but I need to find a safer way to degrease birds. Any suggestions? I have heard that there is a new "orange" degreaser. Has anyone tried it? Also, does anyone use Napthol to degrease birds? Are there health risks associated with using Napthol?
