Pine needles can be a pain to clean, but there are a few ways to do it. The first way is to use a plunger. Put the plunger over the top of the needles and push and pull until all of the needles are out. Then put the plunger back over the top of the needles and push and pull until all of them are out. Repeat this process until all of the needles are gone. The second way is to use a vacuum cleaner with hose attachment. Put the vacuum cleaner over the top of the needles and turn it on. When it starts, hold onto one end of the vacuum cleaner hose and place your other hand overtop of that hand’s grip. Push and pull until all of the needles are gone. Then turn off the vacuum cleaner and let it sit for a few minutes so that all of its suction will have died down. Finally, use a paper towel to clean everything off from under the vacuum cleaner nozzle: The needle tips, around its edges, and any other areas that were missed by using either method above.
