Things You Should Know

  • Put your glass pipe in a resealable plastic bag with rubbing alcohol, hydrogen peroxide , or distilled white vinegar so it’s completely submerged.
  • Add coarse salt or baking soda to the bag to help scrub hard-to-reach places inside your pipe.
  • ​​Shake the bag for 2–3 minutes to quickly clean out your pipe. For stubborn residue, let your pipe soak in the bag for 12 hours.

  1. If there are still any large chunks still inside your bowl, use a pipe cleaner or a toothpick to scrape them out.
    • Try rinsing your pipe with plain warm water since it can remove some of the buildup trapped inside.
  2. Bring a small pot of water to a boil . Use enough water to completely submerge your pipe. As soon as the water is boiling, turn the heat down to medium-low. [1]

  3. Warm up the pipe in your hands or under warm water to ensure the temperature change doesn’t break it. Set your pipe in the pot so it’s completely underwater. [2]
    • Keep your eye on the water level to make sure it doesn’t evaporate since the heat could cause it to crack. If the water level starts to get too low, add more warm water to your pot to cover your pipe.
  4. Take your pipe out of the pot with a pair of tongs and hold it with an oven mitt. Run a cotton swab or pipe cleaner through your glass pipe to wipe away any resin that’s still trapped inside of it. Then, let it dry completely before using it to smoke. [3]
    • Avoid rinsing your pipe underneath cold water since the quick temperature change could cause the glass to shatter.
    • If you still see residue inside of your pipe, try boiling it again for another 20–30 minutes.

Rubbing Alcohol, Vinegar, or Peroxide

  1. Hold your pipe upside-down over a trash can and gently tap the bottom so any loose particles fall out. Then gently scrape any stuck-on residue with a pipe cleaner , cotton swab, toothpick, or needle.
    • It’s okay if there’s still some residue left on your pipe. Getting rid of the larger loose chunks will just make the cleaning solution work more effectively.
  2. Use rubbing alcohol for the fastest, most effective clean since it breaks apart resin the best. If you want to clean your pipe without alcohol, then use hydrogen peroxide or white distilled vinegar instead. [4]
    • If you’re cleaning a bubbler pipe that has multiple pieces, take them apart and put them in separate bags to clean.
    • Use 99% rubbing alcohol if you have some since it’s the strongest cleaner. It’s okay to use a lower concentration, but it may not strip all the resin and tar off of your glass pipe.
  3. Use coarse sea salt or Epsom salt if you have it since it will scrub away the resin easier. Otherwise, table salt will work if you need to clean your pipe quickly. [5]
    • Salt acts like an abrasive on your pipe to clean out buildup that’s hard to reach inside your pipe.
    • If you’re using vinegar, try adding baking soda instead of salt. It will still act as an abrasive, but it will also make a bubbling reaction that can help loosen residue on your pipe.
  4. Start by gently shaking the bag so some of the salt goes inside your pipe. Then, put your fingers over the openings and vigorously shake the bag for 2–3 minutes so the cleaning solution breaks apart the resin. [6]
    • Hold onto your pipe firmly so it doesn’t slip out of your hands and break.
  5. If you still see buildup inside your pipe, leave it inside the bag and let it sit in the cleaning solution for about 12 hours. The next day, shake the bag to get rid of any buildup that’s still stuck on your glass pipe before dumping the cleaning solution out down the drain. [7]
  6. Hold your pipe underneath hot water from your faucet to clean out any resin and leftover solution. Keep running water through your pipe until it comes out clear. [8]
  7. Dip the end of your pipe cleaner or cotton swab in your cleaner and gently rub it into any leftover stains. Give your pipe one final rinse when you’re finished and let it dry completely before smoking with it again. [9]

Alternative Cleaning Methods

  1. Try denture cleaning tablets for a quick clean. Put your glass pipe inside a plastic container and fill it up with enough hot water to submerge the bowl. Then, drop 2-3 tablets into the water and let your pipe soak for about 30 minutes. Scrub off any leftover residue with a pipe cleaner before rinsing the pipe with warm water. [10]
    • Denture tablets may also help get rid of surface stains on the glass.
  2. Use a dedicated pipe cleaning solution made for glass pipes. Read the instructions on the cleaning solution you get since they may vary between brands. Some will have you fill your pipe with the cleaner and shake it for 1–2 minutes to remove the residue. Others may have you soak your pipe in the solution for a few hours before rinsing it out. [11]
    • Avoid using other household cleaners on your pipe since they could leave the taste of chemicals inside your pipe when you smoke from it.
  3. Put your pipe in the freezer for 30 minutes to an hour so the residue hardens up. Then, quickly scrape at the resin with a toothpick or needle to break it apart. Try to remove as much of the resin as you can within a few minutes before it starts feeling gummy again.
    • If the resin becomes sticky or hard to work with again, put it back in your freezer for another 30 minutes.
    • Freezing your pipe might not be enough to completely clean it, but it will help remove large pieces of residue to make other cleaning methods more effective.
