How to clean naptha to resuse it

[Shea25]

I have some used naptha I used to clean some morning glory seeds, its all I have right now is there any way I can clean it to re use it

 

[memo]

I don't know what would be in it after washing morning glory seeds. I was thinking that you could probably wash alkaloids out by shaking with acidic water then separating that out. Oils would be another matter and to do a proper job you would probably need a Rota-vap or the like.
