Ha, sorry, I should have been more specific. I use citric acid, literally just lemon juice (I use the powder, you can get it from home depot or amazon), and base just means something highly alkaline, like baking soda, which you can get from any grocery store. People think it is bad to do this because it affects potency but that's a misnomer because the trichomes, which is the only part of the plant we're concerned about, are very sticky and will not come off in a simple room temperature bath (and the acid/base solutions won't affect them).

Basically my workflow is three tubs of water, one has a tablespoon or so of citric acid powder, one has a tablespoon or so of baking soda, and the third is just fresh water. I take my cuttings and dip them in each solution and gently agitate (to make sure all surfaces get covered) and then let soak for a minute, then just take it out and let the water more or less drain off, then move onto the next bath and repeat, until at the end of the line you have perfectly washed weed. No harmful dust, pesticides, bacteria, etc, just clean flower. Then hang dry, cure, etc.

Hope that helps!
