Never had taste or burn issues - i do the hot water wash first , then a cold water final . Dunk and twist in water by STEM ONLY . Hang to drip dry then on mesh rack ... lots of variants to this .
I modded a slightly different step ( if small amount if PM is found ) i mix water / peroxide spray bottle ... spray buds before dunk , then proceed to bud wash. It really cleans off that shit without much effort. End product looks picture perfect .
Just looking at the leftover wash water will convince anyone . I dont do all grows just once in awhile if i notice issues.
