# 1 You can best clean your water pipe in the kitchen, so you have a working space. First you put some warm water in your water pipe and permit it to soak for a moment. Be careful! Don’t fill your water pipe with water that is too hot, because it can break your glass water pipe. After a while discard the unclean water pipe water.
# 2 Include some sort of cleaning solution, like Formula 420, in your water pipe and blend it with water. Put your thumb on the downstem (and carb hole) and your other hand on the mouthpiece. You can also use plastic cellophane to seal the mouthpiece. Then it’s easier to hold the water pipe with your free hand for better grip. Shake your ice water pipe to ensure the cleaning product reaches every spot. You can also let the mixture sit in your piece for a minute.
# 3 Continue this process of shaking your piece with the mix of water and detergent till all dirty bits are gone. You can hold the water pipe flat, to reach all parts of your percolator, if your piece has percolators. If there are still unclean parts, then repeat the process. You can refill your water pipe with your choice of cleaner and water, if the mix gets too dirty to clean your water pipe.
And after that: ... Shake it again!
# 4 If your piece is clean and tidy, you can fill your water pipe once again time with warm water. This helps to flush out any remaining cleaner.
#5 Last but not least, enjoy smoking!
