• How do I clean my piece?

    1) Cleaning Glass with Alcohol Solution:

    If you’d like to make your own pipe-cleaning solution from scratch, you’ll need salt and rubbing alcohol. A small bottle of isopropyl alcohol and coarse, kosher salt (used to brine) work best, and both should be available at your local grocery store. Mix equal parts of the alcohol and salt in a bowl or tupperware large enough to fit the piece you’d like to clean. Depending on the strength of the solution, it may be powerful enough to fade the label on the outside of your pipe. To protect your label, simply cover it with a strip of blue painter’s tape. Remove the tape when you’ve finished cleaning and rinsing your pipe. Let the piece soak in the saline mixture for anywhere between 1 hour and 1 day. The longer it soaks, the easier it will be to break up any tar and resin. Take the soaked pipe and fill it halfway with the solution using a funnel or measuring cup. If you’re cleaning a water pipe, consider blocking any joints with a GRAV® cleaning plug, available in 14mm and 19mm. If you’re cleaning a bubbler or hand pipe, simply block the necessary openings with your fingers. Shake the pipe vigorously but carefully. It’s best not to shake too close to any hard surfaces in order to avoid accidentally hitting the pipe against something and breaking it in your hand. Also, just in case your fingers slip and solution leaks out, you may want to avoid shaking near any fabrics or items that could be stained. As you shake the pipe, the solution should break up the tar and expose clean glass. Shake for 3 minutes, then empty the pipe down your kitchen sink while running hot water. You may need to refill the pipe and shake again multiple times until the piece is satisfactorily clean. If you find a particular spot is not getting clean, use a Q-Tip or pipe cleaner soaked in the solution to reach the spot and scrub it manually. When you’ve finished cleaning, rinse the pipe, first with hot water to remove any layer of remaining solution and then cold water to prevent the piece from fogging. Let it dry before using it again.

    2) Cleaning Glass with Soaker:

    Soaking your pipe in a cleaning solution is the simplest and most thorough cleaning method. There are several pipe cleaning solutions on the market. The most important aspect to consider is whether the solution could leave behind any chemical residue that would be harmful if smoked. We recommend Grunge Off, both for safety and efficacy. Grunge Off is citric acid-based and can be found at most head shops and several online retailers. Whichever cleaning solution you decide to use, just make sure it’s intended for use with glass pipes or stemware. Depending on the strength of the solution, it may be powerful enough to fade the label on the outside of your pipe. To protect your label, simply cover it with a strip of blue painter’s tape. Remove the tape when you’ve finished cleaning and rinsing your pipe. If you’re cleaning a hand pipe or bubbler, find a container that will fit your piece. Place your pipe in the container and fill it with your chosen cleaning solution. Submerge the piece entirely and rotate it to allow any air bubbles to escape. Let the pipe soak anywhere between one hour and one day. The longer it soaks, the more tar will be dissolved and removed from your piece. Once you’ve finished soaking it, rinse your pipe over your kitchen sink with hot water. Most of the tar should have broken up and will be washed away. If there are any troublesome spots remaining, use a Q-Tip or pipe cleaner soaked in solution to scrub it manually. Rinse the piece again with cold water and let it dry before using it again. The same process applies to water pipes, except instead of filling a container with solution, simply fill the pipe itself. Block the pipe’s ground joint with a GRAV® Cleaning Plug available in 14mm and 19mm, and use a funnel to fill it with solution.

    3) Cleaning Glass with Shaker:

    A shaker solution is the fastest way to clean your pipe. Fill your pipe a little more than halfway with the solution and seal off all openings. Joints can be sealed using GRAV® cleaning plugs, available in 14mm and 19mm. You can cover smaller openings, like mouthpieces and carbs, with your fingers. Shake the pipe vigorously but carefully. It’s best not to shake too close to any hard surfaces in order to avoid accidentally hitting the pipe against something and breaking it in your hand. Also, just in case your fingers slip and solution leaks out, you may want to avoid shaking near any fabrics or items that could be stained. As you shake the pipe, the solution should break up the tar and expose clean glass. Shake for 3 minutes, then empty the pipe down your kitchen sink while running hot water. You may need to refill the pipe and shake again multiple times until the piece is satisfactorily clean. If you find a particular spot is not getting clean, use a Q-Tip or pipe cleaner soaked in the solution to reach the spot and scrub it manually. When you’ve finished cleaning, rinse the pipe, first with hot water to remove any layer of remaining solution and then cold water to prevent the piece from fogging. Let it dry before using it again.

    4) Cleaning Grinders:

    The most important thing to remember when cleaning your GRAV® Grinder is that certain components should never get wet. Ideally, the only pieces to wash are the lid and the bottom row of teeth. You can scrub the teeth under hot water using a spare toothbrush or other firm-bristled brush. Dry these components thoroughly before reassembling your grinder or your whole life will just be clogs. The central chamber can be separated from the assembly and wiped clean using a damp cloth or paper towel. The magnetic kief screen can be gently cleaned with a spare toothbrush or other firm-bristled brush. The bottom-most component - the kief compartment - should never be cleaned. Its purpose is to store the kief that accumulates from grinding plant matter, and it should only be emptied using the curved GRAV® Scraper included with the grinder.

    5) Cleaning the Fire-Button™:

    The original Fire-Button skillet was removable, but not designed to be disassembled for cleaning. If you have this single-piece skillet, you can clean it using a Q-Tip. Heat the skillet until red hot, then let it cool to a point that the plant extract is still soft but no longer smoking. Gently clean the surface of the skillet with the Q-Tip until it’s free of excess material.

    The current Fire-Button skillet can be disassembled for easy cleaning. Each pack of replacement skillets comes with one titanium housing assembly and five ceramic skillet cores. Unscrew the lid of the titanium housing to access the skillet core. Remove the core and wipe it on all sides with the end of a Q-Tip to remove excess material. Also clean out the inside of the titanium housing before reassembling the skillet. Regardless of what version of skillet you have, we recommend regular users replace their Fire-Button skillet every 30 days. Replacement skillets are available for purchase here!

  • Helix and Glycerin Multi Kit Issues

    Our Helix and Glycerin Multi-Purpose kits are excellent for smokers who want versatility from their hand pipe.  Both kits can be converted from simple hand pipes to bubblers or vapor straws for use with plant extract.  Assembling and reassembling your multi isn’t too tricky, but there are a few things to keep in mind.  Each multi has a mouthpiece component.  The Helix Multi’s mouthpiece is the characteristic Helix Venturi chamber.  The Glycerin Multi’s mouthpiece is the marble-capped chamber filled with dyed vegetable glycerin.  The mouthpieces can be used with any of the three accompanying heads, but only one head at a time can be used.  The mouthpiece and head are secured by a joint clamp.  To remove the clamp, simply pull it off with your thumb and forefinger.  The clamp requires moderate pressure to snap the clamp on and off of the joint, but if for whatever reason you’re experiencing difficulty getting a clamp on, please don’t force it.  Excess pressure can break the joint, and it’s possible the clamp is too small.  Reach out to our Support Team and we’ll help you resolve the issue safely.

  • Glass Blunt Issues

    The most common problem with our glass blunt concerns the heat-shrink tubing that connects the two glass components.  If the tubing gets wet, it can lose its snug fit.  To re-fit the tubing, assemble the blunt as desired and then heat the tubing with a blowdryer.  This solution should both dry the wet tubing and re-shrink it to fit more snugly around the glass.

  • Grinder Issues

    Be mindful of sharp edges when handling our grinders as their teeth are very sharp, intended for shredding raw plant matter. Occasionally, our colored grinders can lose some of their superficial dye coating during the grinding process. This material is non-toxic but can affect the flavor of your plant matter. We recommend you twist the grinder several times before the first use to shed any excess coating.


    If your grinder becomes stuck, use a jar opener (the rubber variety) to help loosen it.  If this continues to happen, consider cleaning your grinder referring to the cleaning section of our FAQ list for guidance.

  • Fire-Button™ Issues

    Because the Fire-Button™ is electronic, please read its guidelines (included in the box) before using it. The Fire-Button™ can only be used with the charger with which it’s sold.  Otherwise, the battery can explode from an excess of unregulated charge. If over time, the charger doesn’t glow green and you believe it’s defective, please reach out to our Support Team for further assistance. You shouldn’t use your Fire-Button™ while it charges as this can cause the unit to overheat which degrades its lifespan. Because the battery is sensitive to temperature, you shouldn’t expose your Fire-Button™ to excessive heat, such as leaving it in a car or outside.


    When using the Fire-Button™, always be mindful of the skillet as it can burn you on contact if you touch it before it cools down. Also, be careful how much plant extract you load. The recommended load is about the size of a BB.  If you load more than this, you may flood the skillet. To avoid this, try rolling your product into an oblong shape and slowly touching it to the skillet.

  • Helix™ Issues

    The most common issue with Helix™ products is the airflow.  If you don’t think your Helix™ is spinning the smoke properly, test its function using a small piece of paper about the size of a BB.  Place the ball of paper in the Venturi chamber mouthpiece.  If you’re testing a hand pipe, cover the carb with your finger.  If you’re testing a water pipe, make sure the bowl is in place.  Inhale from the mouthpiece as you would during use, steadily but firmly pulling air through the Venturi chamber.  The ball of paper should spin around inside the chamber in a consistent clockwise motion.  If it doesn’t, please reach out to our Support Team for guidance.


    The purpose of the Helix™ design is to aerate and cool smoke.  However, this can sometimes result in hits that are too light for veteran smokers.  Please be aware of a product’s intended use before purchasing anything from GRAV®.  If you have a Helix™ but want to occasionally take more traditional hits, you can cover one or more of the air intake holes temporarily with a small segment of clear tape.  The more holes you cover, the denser the hits will become.  Be advised: doing this will disrupt the spinning action until the tape is removed.

  • Downstem Issues

    The most common issues with downstems are issues with fit.  Sometimes the bulb of a downstem might not fit through the opening of the ground joint.  Sometimes the downstem is too long, and its tip hits the base of the water pipe.  In either of these cases, please reach out to our Support Team for a replacement.


    Downstems can get clogged, limiting airflow through the pipe.  If the downstem is removable, simply take it out and clean it.  You can refer to the cleaning section of our FAQ list for guidance.  If the downstem is fixed inside the pipe, you’ll need to clean the entire pipe to unclog it.


    Downstems can get stuck inside a ground joint, such that it feels like they can’t be removed for cleaning.  In this case, try heating the joint with a lighter or torch to loosen the seal.  If this doesn’t work, try taking something that vibrates - such as an electric toothbrush - and hold it against the side of the joint.  The vibrations should loosen the seal between the downstem and joint, allowing you to retrieve the downstem.

  • Is it possible to suffer from GRAV addiction?

    Yes, and it’s very serious.  There is no known cure.

  • Can I tour GRAV’s facility in Austin?

    In March of 2017, we moved to a new warehouse in South Austin.  We’re still in the process of building out the new space and making it presentable for visitors.  As soon as we finish construction and save up enough for a tour guide and golf cart fleet, we’d be happy to send you an invitation.  Until then, you’ll have to content yourself with exploring our site and, if you’re lucky, the beautiful city we call home.

  • Where can I order GRAV products outside the United States?

    There are a number of online retailers that ship internationally, some of which are located outside the U.S.  Please check out our Store Locator page for the retail partner closest to you.

  • What is American Helix?

    The Venturi chamber mouthpiece featured across the Helix line was developed by a Texan glassblower named Will Menzies.  Will partnered with Dave Daily, GRAV’s founder, to rebrand the V-Tech hand pipe as the Helix Classic, and together they created several new designs to form the basis of the Helix family.  As the popularity of Helix grew, Dave became more interested in production and development of new designs, while Will focused on artistic variation.  They parted ways, and Will created a new company called American Helix.  They make Helix pipes in a more heady style and only employ American glassblowers.  Our two companies have different styles, audiences, and products, but we share a common origin story.  GRAV pays royalties to American Helix to continue using our GRAV Helix designs, and we’re proud to support Will and all our amazing and talented collaborators.

  • Where are GRAV products made?

    GRAV sources most of our raw materials and finished products from a factory in Tianjin, China, with whom we’ve worked closely for years. We consider the glass artists there to be part of our family, and we’re deeply invested in their success and well being. Members of our Product Development and Leadership teams visit Tianjin regularly to maintain an efficient flow of ideas and communication. We’re proud of the partnerships we’ve built overseas, and they’ve allowed us to more than double our American team, support local glass artists, and bring exciting new products to market at an accessible price.

    Every piece we sell is designed, prototyped, inspected for quality, and shipped from our headquarters in Austin, Texas. The fact that most of our production is done overseas makes it possible for us to elevate our American staff into 21st-century careers, invest in new ways of doing business (including this site), and focus on our strengths - product design, thoughtful marketing, and impeccable customer service.

    Select products or batches of products are produced in Austin at our state-of-the-art hot shop, where we rent glass-blowing stations to several local glass artists. If you'd to know the manufacturing life cycle of a specific product, please reach out to support@grav.com.

  • Does GRAV make carrying cases for any products?

    GRAV doesn’t currently make carrying cases for any of our products.  However, one of our team members has an incredible idea in the works that may be the perfect solution for transporting scientific glass.  If you subscribe to our newsletter, we’ll let you know as soon as any new products - including cases - are about to launch.

  • How can I find replacement components for my GRAV product?

    Many replacement components are available through GRAV®.  If you’re having difficulty finding a specific piece, just ask our Support Team and they’ll work with you on finding the right component. Hit that chat box in the corner if you need help right away!

  • What is GRAV’s replacement policy?

    Here’s the short and sweet answer. If you receive a broken item, we’ll replace it. If something is missing from your order we’ll replace it. If you receive an incorrect item, we’ll replace it. And if a GRAV product is defective and you report that defect in the first 6 months of owning it, we'll settle the issue with store credit. For a full explanation of our replacement policy, please visit the Replacement Policy Page. All claims questions can be sent to support@grav.com

  • What kind of glass does GRAV use?

    GRAV uses the finest borosilicate, a type of glass with a high silica content that’s heat-tolerant and chemically inert.  These qualities make borosilicate perfect for pipes, as it can withstand and disperse heat from a lighter or torch and doesn’t pollute smoke in any way.  Some of our components, namely our nails and bangers, are made from quartz.  Quartz is 100% silica, making it even more durable than borosilicate.  However, it’s more expensive than borosilicate, which is why we only use it for smaller pieces.

  • Does GRAV offer custom products?

    GRAV currently doesn’t offer customization on any products.  We’re still a relatively small company, and keeping up with the demand for our current catalog is a hefty task.  We look forward to growing to a point that customization can be part of our product offering.

  • Does GRAV® offer repairs?

    As a result of the cost of shipping back and forth between Austin and our customers, GRAV® does not offer repairs. If you think a defect in your piece might have some kind of work around, check out the Diagnostics Section of our Support Page for troubleshooting tips.
