Thanx for the info. SWIM don't know from where to buy Limonene or what that is. Also SWIM have bought naphta already (Zippo Lighter fluid).

SWIM will be using Marsofold's tek. Very confused about the measuring units. SWIM living in eastern Europe, did a search about gallons and pints, and this is what came up for example:

Liters per Gallon

There are 3.785411 liters per gallon (US).

4.54609 liters per gallon (UK).

Same with pints...

So , there's a pretty big difference. What type of "gallons" does the Marsofold's tek use ? And why are there so big differences between the teks concerning the water-vinegar ratio. Another tek (Lextek i think) says 1 part vinegar to 3 parts water.

Also, all the white vinegars here, where SWIM lives are 9% not 5%. How should this impact the extraction ?
