8. Boiling
Before you boil it, you should attempt to remove and save as much kief as possible. Any kief that goes into the boiling water will no longer contain the potency to get you high. So first freeze the grinder to make the residue less sticky. Then hit it with the brushing technique from the previous step.
Get as much of it out of the grinder and transfer it into a nice smell-proof container for future use. Once you feel you’ve got most of it, you can boil the grinder for five to ten minutes.
Use a paper towel to remove any residue that survived the boiling. Q-tips work great for getting between the teeth. For those strapped for time, there’s a way to make use of your remaining kief without having to do the freezing and brushing.
It doesn’t sound too sanitary, but some people boil or simmer their grinders in milk. The fat from the milk helps extract the THC from any kief or plant matter in your grinder.
Then, they remove the grinder, pour the remaining milk into a glass and let it cool. Once it’s cool enough, drink it to get an intense edible high. Make sure you lick your milk stache so no THC goes to waste.
If you don’t want to drink milk that contained your grinder or bother with the extra steps to save your kief, there’s another way.
