basslover, you really go all out!! soaking vine in crossbow sounds great but in a big area that is a lot of zip lock bags!!
My .02 on tecnu. Read the label, active ingredient says: "deodorized mineral spirits" They put a fancy web page up, give it a fancy name, charge $12 per bottle. They tell you to wipe down everything that has oil on it as it 'separates the oil from your skin or clothing' (clothes, shoes, skin, pets etc)
I say save your money and just use mineral spirits instead. You can get about 4 gallons for $12.
