How to clean a glass sherlock pipe
The best way to clean a sherlock pipe
is either with rubbing alcohol or some sort of 420 cleaning solution. If the situation is a matter of light residue build up, it may be possible to fill the interior of the pipe with your choice of solution and then shake it around while sealing off both ends. Be careful, but q tips and other similar cleaning tools can be used to aid in your pipe cleaning process.
If needed, you may have to soak the pipe in a cleaning solution in either a plastic bag or some shallow bowl of some sort. Especially with an airway and bowl piece covered in heavy residue, this may be the best option. But again, various tools can be used to help clear the resin out from the sherlock pipes. The cleaning solution will not harm the actual glass, but depending on what is used exactly, overtime logos not blown into the glass may fade or be impacted in some way.
Some will recommend putting the sherlock glass piece in boiling water. Although it has been done many times, especially with the boiling temperature, if you have a sudden change to a colder temperature, the glass has the higher potential to crack right in half. If you prefer a more natural way around some sort of cleaning solution, you don't need to boil the water, but can soak the unit in warm water to loosen the resin particles and help the pipe cleaning process.
