I have done several extractions with lye and HCL using my buchner funnel. I am now interested in making a cannabis tincture using my buchner funnel to filter an alcohol/cannabis mixture. Is this safe to do? Can the funnel and vacuum flask be cleaned sufficiently so that i won't be ingesting any lye or acid with my tincture and if so, how should i clean it? Anyone know how harmfull it is to ingest minute quantities of lye or hydrochloric acid?

Any help is greatly appreciated!

Rinse & soak in water, several times. This should take care of it.

there is no need for that, lye and hcl are both well water soluble
As a kemist I never met ILPT in physical form and never talk to him. He share his wisdom, trough my mind, telepathicly only. Please don`t prosecute me, for his possible illegal activities. He is bonkers about chemistry and doesn`t even exist in this primitive reality !!!

As kemist said, wash with warm water, it will easily dissolve any trace acid and base.

If there might be traces of solvents, wash with ethanol/vodka

salt is a safe abrasive for glassware
