My first extraction I want to be perfect, so, I have two questions for the materials I did found after a lot of searching.

Instead of naptha , I found this:
"White Spirit 100% A3 solvent of middle alyphatic naptha", is this ok?

and about lye I found a local product that they claimed to be pure NaOH (for soap)
BUT it isnt in air-sealed package..
Is there something wrong?

No need to answer this I did the cd evaporation test and it left some tiny white dots so I shoudnt go on with this
