It was only a very feint residue and I have had the shellite for a long time for general household use which is why I assume its the inside egde of the bottle that has been dissolved.

Sce@#ys toluene also leaves a very feint residue but again this was an old can (but metal) and was at the end of it. Tests much earlier came out better.

I wouldnt be surprised if all the diggers napthas are from the same source just relabelled for targetting different consumers.

Im starting to think the cleanest way for Aussies ( as localy sourced fumaric acid isnt available here) is a double or triple acid base with thorough filtering and liquid reductions at the acid stage then either a water crystalization (if after just dmt) or a sodium carb and dry ipa freebase and extraction.

Timely and requires much work but should yeild a very clean non toxic end product.

Just did 2 test with zi@#o premium and both times evaporated without a trace will try undu again and give it more time to completely evaporate.

Edit: ok so undu this time left no trace maybe it was something from the tap water used to clean the dish that showed up.

With the weather so hot its a great time to test these products.
