So the other day i picked up my bong to have a toke when i realised the last time i used it i never emptied the water,
It had gone horrible and mouldy and was caked in resin
Being the lazy stoner that i am i had put off cleaning the bong for a while as it's quite tall and impossible to get to the bottom.
After seeing the mold though i decided it's time and hatched a cunning plan
For this you will need some isopropyl alcohol, some table salt and an air pump
Start by adding some salt, then pour in some iso till it's just bellow the hit hole and give it a good shake
Whack the airline through the hit hole and get it right to the bottom of the bong
Leave it for an hour or so and keep re positioning the airline every now and then.
Lovely clean bong
It did take a little bit of rinsing to get the last bit of crud out and the bowls i had to do separately with iso to get them clean but it worked a treat on the hard to reach places on the bong.
If you try this make sure you do it in a well ventilated area and don't smoke or you'll blow yourself to pieces
