if by clean evaping you mean putting all the solvent into a plate, let it breed for hours so it evaporates completly without any contamination on it, yes, it was a clean evap. it was my first zippo lighter pulls from my mimosa solution. It smell id say like zippo lighter fluid ( i guess the smell remains on the plate) and a lot like the mimosa solution. I dont have a scale to weight. but putting it together is less than a drop of water. i'll post a picture later for you bro.
