The hot water just makes it quicker to flush them so you're not there all day running water through. Don't need to boil it. Not even necessary, just saves time. I just use as hot of water as my hands can take out of the bathtub spoutNo I am not pouring boiling water on my ladies
I am pouring water that has just barely started to come to a slow boil. Then I pour that on fresh coco in the sink just to be safe lol. Then I rinse with tap water and then buffer in a bucket with 500ppm calmag solution overnight like Jp suggested
