Ok, I guess I've found some answers.
As far as I can tell:
Mineral spirits = white spirits, which is what danes call "mineral turpentine" (directly translated)
Turpentine is what danes call "vegetable turpentine".
But Naphtha still gives me problems.
When checking both of the above, the label says they contain some naphtha.
But I haven't been able to find pure naphtha.
Grill-starter liquid was mentioned, but all the grill liquids I can find, seems to be part petroleum, which I presume is not naphtha....???
There's two reasons that I try to get clear answers on this.
One is that citrus solvent is mentioned for cutting tung oil, but I can't find that stuff anywhere.
(only place that might have something similar, is this newagy health shop, which sells some oils, but they come overpriced in rediculously small containers... )
The other is, that naphtha is mentioned for cleaning the wood before applying tung oil, but as stated, I can't find pure naphtha.
So I wonder if I can use mineral spirits instead for both cleaning, and cutting the tung oil.
(I'm a little nervous, 'cause I think I remember reading somewhere, that mineral spirits would dissolve the cellulose in wood.... )
:help:
