Detonox is the recommended detergent for hydroponic and outdoor growers, leaving your crop clean and free of unwanted residue. Especially effective with cannabis / marijuana -- see for yourself!
Or as Alconox would say:
Detonox is a non-caustic detergent for exceptional removal of cosmetic and pharmaceutical polymers, sticky extracts, resins, creams and lotions. Concentrated, highly emulsifying and penetrating formula is free rinsing, and leaves no residues.
