Cleaning up hardware store naphtha?

[VoyagerGrey]

It's getting harder to find readily available to the consumer where I am. There was a paint supply shop I got a gallon form last time, it worked well and I still have some, but they no longer carry it. I found another source, bought a gallon to test, evap test doesn't look good.

While I was searching for suitable products / brands to use I remember reading a thread on here about sourcing naphtha and at some point the discussion turned to a a process for potentially cleaning up impure naphtha, with a series of washes- acid, base, water...something like that. I didn't read too carefully because it would be much easier to just find a clean product. Now it doesn't look like I can. and I can't find the thread! Does this ring any bells for anyone? the title of the post was something like "washing hardware store naphtha" but I can't pull it up in search.

You can extract with xylene as well, and it actually works better ( extracts more) than naptha, but its awful smelling stuff and evaporates more slowly. I evaporate it outdoors and use a fan over it to evaporate it more quickly. It takes out more matter from root bark that give the yield more of a dark effect when used unless it's purified.

I remember the thread too. Wait a few days and I may yet dig it up again. An alternating series of acid and base washes, ideally followed by distillation, would clean up some non-naphtha ingredients/impurities. The exact course of action would depend on what you're trying to remove.

Use a mini A/B to recover product from xylene - that way you get to re-use the xylene, and cause less of a stink.
