Says what? Degummed? The same oil used for say industrial, chemical, or other purpose will say noting about gum. It is a long standing model hobby marketing hype. May have been used for castor motor oil also. There is no actual gum removal. The gum you get from sitting up is simply oxidized castor. Blown castor is partially oxidized, it may seem to have gum. Bakers A may have gum, but it is actually not removed from Bakers AA, the first press has no gum to removed. It actually is a poor way of expressing the truth. There is no gum in the oil, but there was actually no process to remove the gum. I guess gumless didn't sound right. Sounds like it has poor dental work.
