How often should you change the water in a glass bong and why?

If you enjoy smoking herb or tobacco from a glass bong, you probably know how important it is to keep your piece clean and fresh. Not only does a dirty bong look and smell unpleasant, but it can also affect the quality and flavor of your smoke, as well as your health. In this blog post, we will explain how often you should change the water in your glass bong and why, as well as how to properly clean your bong using simple household ingredients.

Why you should change the water in your glass bong

Changing the water in your glass bong is essential for several reasons:

  • It prevents mold and bacteria growth. Water is a breeding ground for microorganisms, especially when it contains organic matter such as tar and resin from your smoke. If you leave the water in your bong for too long, it can become contaminated with mold and bacteria that can cause respiratory infections, allergies, or worse. Mold and bacteria can also clog up your bong and make it harder to draw.
  • It improves the taste and smoothness of your smoke. Fresh water helps to filter out some of the toxins and impurities from your smoke, making it smoother and less harsh on your throat and lungs. It also preserves the natural flavor and aroma of your herb or tobacco, without adding any unpleasant or stale tastes. Dirty water can ruin your smoking experience by making your smoke taste bitter, sour, or musty.
  • It extends the lifespan of your glass bong. Water is corrosive and can damage your glass bong over time, especially if it contains chemicals or minerals. Changing the water regularly can prevent your glass from cracking, chipping, or staining. It can also prevent the buildup of resin and tar that can make your bong look dirty and reduce its functionality.

How often should you change the water in your glass bong

The general rule of thumb is to change the water in your glass bong after every smoke session. This will ensure that you always have fresh and clean water for your next session, and that you avoid any potential health risks or unpleasant tastes from dirty water. However, depending on how often you use your bong and how much you smoke, you may need to change the water more or less frequently. Here are some factors to consider:

  • The frequency of use. If you use your bong every day or multiple times a day, you should change the water at least once a day. If you use your bong occasionally or sporadically, you should change the water before and after each use.
  • The amount of smoke. If you smoke large amounts or take big hits from your bong, you should change the water more often than if you smoke small amounts or take small hits. This is because more smoke means more tar and resin that can accumulate in the water and make it dirty faster.
  • The type of herb or tobacco. Different herbs and tobaccos have different levels of potency, moisture, and additives that can affect how quickly the water gets dirty. For example, dry herb or tobacco may produce more ash and dust that can cloud the water, while moist herb or tobacco may produce more sticky resin that can coat the water. You should also avoid adding any flavorings or sweeteners to your herb or tobacco, as they can attract mold and bacteria to the water.
  • The quality of water. The quality of the water you use for your bong can also influence how often you need to change it. Tap water may contain chlorine, fluoride, or other chemicals that can alter the taste of your smoke or damage your glass. Bottled water may contain minerals that can leave deposits on your glass. Distilled water may be too pure and lack minerals that can help filter out toxins from your smoke. The best option is to use filtered or purified water that is free of contaminants but still has some natural minerals.

How to properly clean your glass bong

Changing the water in your glass bong is not enough to keep it clean and fresh. You also need to deep clean your bong regularly to remove any stubborn resin and tar that can stick to the glass and the accessories. You don’t need any fancy products or tools to do this; you can use simple household ingredients such as isopropyl alcohol and coarse salt. Here are the basic steps to clean your glass bong:

  1. Separate all the parts. Take apart your bong and separate the glass body from the slide, the bowl, and the stem. This will make it easier to clean each part thoroughly and prevent any damage from shaking or scrubbing.
  2. Rinse out the pieces in hot water. Use hot water to rinse out each piece and remove any loose chunks of resin or ash. Be careful not to use boiling water or cold water on a hot piece, as this can cause the glass to shatter. If your piece is cold, start with lukewarm water and gradually increase the temperature.
  3. Fill your bong with isopropyl alcohol and salt. Pour some isopropyl alcohol (preferably 90% or higher) and some coarse salt (such as kosher or sea salt) into your bong. The alcohol will dissolve the resin and tar, while the salt will act as an abrasive and scrub away any stubborn stains. Make sure the alcohol and salt mixture covers all the areas that need to be cleaned.
  4. Shake it up and let it soak. Plug the holes of your bong with your fingers, rubber stoppers, or plastic wrap, and shake it vigorously for a minute or two. This will help the alcohol and salt mixture reach all the nooks and crannies of your bong and loosen up any stuck-on resin. Then, let your bong soak for some time, depending on how dirty it is. You can soak it for a few minutes, a few hours, or even overnight.
  5. Clean the slide, the bowl, and the stem. While your bong is soaking, you can clean the other parts using the same method. Place them in resealable plastic bags or containers filled with alcohol and salt, shake them up, and let them soak. You can also use cotton swabs, pipe cleaners, or bottle brushes to reach any hard-to-clean spots.
  6. Rinse with warm water and dish soap. After soaking, pour out the alcohol and salt mixture from your bong and the other parts, and rinse them well with warm water. You can also use some dish soap to remove any traces of alcohol or salt and make your bong smell fresh. Rinse until there are no bubbles or residues left.
  7. Let it dry completely. Before using your bong again, make sure it is completely dry. You can use a towel, a paper towel, or a hair dryer to speed up the process. You can also let it air dry for an hour or so. Make sure there is no smell of alcohol left before smoking from your bong.


Cleaning your glass bong is not a difficult or expensive task, but it can make a big difference in your smoking experience and your health. By changing the water in your glass bong after every smoke session and deep cleaning your bong roughly once a week, you can enjoy smooth, tasty, and safe smoke from your herb or tobacco. You can also extend the lifespan of your glass bong and keep it looking shiny and new. Happy smoking!
