Make sure that you rinse the glassware, strainer/terry cloth,
chopping board, and knife with EtOH before starting the
extraction procedure. Detergents utilized in cleaning things
may leave chemical residues on the utensils,
invisible in most cases. These residues may interfere
with the process, and the resulting extracted psy.
