No, I was looking for it and it looks like the only way it to buy lighter fluid. As I said I finally went food safe teks such as Limtek to avoid nasty residue as much as I can considering I'm not a lab professionnal.

Anyway I bought a small bottle of Zippo fluid lighter wich looks clean after evaporation (no smell, no residue) that I just used to clean something out.

I'm surprised they sell sodium hydroxide in castorama (I use calcium hydroxide as a base, white vinegar as a acid, d-limonene as NPS, and salting out either vinegar or fumaric acid) which I couldn't find.

I'm really up for buying glassware as it is crucial now to work in a more organized setting and so much enjoyable to have proper tool for proper homework !

There are many teks around to try so there is always alternative concerning slovents.

Thanks for the casto advice  SWIM will try the BLAB if he find IPA (any idea ?)
