Water Wash Tek: Clean DMT With Sodium Carbonate

If you’ve ever extracted DMT, you’ve probably heard the term “water wash”. But what is it? As you may know, when extracting DMT certain chemicals are used to complete the extraction process. These chemicals are usually strong base ingredients like Sodium Hydroxide and solvents like Naphtha, Heptane, etc. These chemicals are not safe for human consumption, yet often they can carry over into your DMT during the extraction. Typically, this is due to poor or improper extracting techniques or, lack of care during the extraction.

There are many extraction guides or Teks on the internet, all with various ingredients, tools, and methods to extract successfully. However, in all extractions, there is always the risk of some of these chemicals carrying over into your DMT crystals. That is why cleaning your DMT before use is always a recommended safety step before traveling to hyperspace.

There are multiple ways to clean your extraction; each method cleans the extracted DMT differently. There is a “Re-x” or “Re-extraction” method. This method primarily aims to remove the visible base or microplant material from your DMT. The visible base is often seen as red or black dots in your DMT. Performing a Re-x allows you to separate these microparticles from your DMT, leaving it safer and smoother when smoked.

But what about the impurities you can’t see? Luckily there’s a clean-up step for that as well called a water wash. Water washing involves washing the solvent containing your dissolved DMT in water to remove water-soluble impurities like Sodium Hydroxide or “Lye”. Tiny Lye molecules can bind to your DMT in the freezing process. This is what often leads to harsh DMT. So to make sure you remove those before consuming your spice you’ll want to perform a water wash.

This guide will cover water washing, how to do it, and what you will need to do it. I’m going to walk you through the process step by step to ensure that your spice is nice and clean before you indulge in space travel. As always in my guides I will provide links to everything you’ll need and detailed pictures for the more visual learners.

The water wash we will be doing is a Sodium Carbonate wash. Sodium Carbonate is a food-grade base easily made at home out of Sodium Bicarbonate or “Baking soda”. Carbonate super boosts the cleaning quality of your wash and acts as a magnet for water-soluble impurities like Lye. We will go over how to make it and use it in more detail as we go.

With that being said, let’s get started!

Ingredients needed for water washing

  1. One gram or more of Extracted DMT (how much you plan to clean will determine the ratios of other ingredients)
  2. 100ml of Heptane per 1 gram of DMT (you can use other solvents like Naphtha as well)
  3. 100 grams of Baking soda or you can just buy pre-made Sodium Carbonate 
  4. 3 tablespoons of pickling salt (any salt will do but I prefer pickling salt for its purity)
  5. 1000ml of Distilled water (any type of water including tap water will work too)

That wraps up all of the ingredients you’ll need to follow along with this Tek. As mentioned above, you dont have to use Heptane. You can also use Naphtha. I prefer Heptane for cleaning because it’s a cleaner solvent and targets DMT specifically while leaving out other unwanted plant materials. Also, if you buy baking soda instead of pre-made Sodium Carbonate, You’ll need to convert it to Carbonate before using it in your water wash. I will be showing you how to do that in this guide. Now let’s move on to the tools you’ll need.

Tools and supplies needed for water washing

Tools needed to conduct a water wash.
  1. Three, quart-sized mason jars with lids
  2. A 4-cup capacity Pyrex measuring cup (can also use a deep pot or bowl)
  3. A magnetic stirrer with 4 magnetic stir bars 
  4. A glass beaker set 
  5. A glass pipette with a good hand pump
  6. An electric kettle for hot water on demand (this isn’t 100% mandatory)
  7. A pot with a lid
  8. A milligram scale to weigh your DMT
  9. A Food scale to weigh your Baking soda/Carbonate
  10. A casserole dish for freeze-precipitating your crystals

Now that we have covered everything you will need, let’s start with the first step of this process: converting our baking soda into Sodium Carbonate. If you purchased pre-made Sodium Carbonate you can skip this step and move on to step #3.

Making the Sodium Carbonate for water wash

The first step in this water wash is making the Sodium Carbonate. Sodium Carbonate is used in this water wash because of its ability to clean and remove water-soluble impurities. Think of it like a Magnet for impurities. If you didn’t buy pre-made Carbonate, then you will need to convert your baking soda into carbonate. This process is simple and takes about 5 to 6 minutes to complete and is also cheaper than buying it pre-made.

1. Begin by weighing out 100 grams of baking soda

Using your food scale, weigh out 100 grams of baking soda. We will not use all of this in our water wash but it’s nice to convert extra baking soda into carbonate for future clean-ups.

2. Place your baking soda in your pot and on the stove

Place 100 grams of baking soda in your pot and put it on your stove on medium-high heat. Using a spoon you will continuously mix the baking soda. As the baking soda heats up, you will notice that the baking soda starts to look wet and clumpy. After it starts looking clumpy, you will notice little geysers from the baking soda’s surface.

This reaction is water molecules and carbon dioxide being released from the baking soda. Keep mixing the baking soda until this reaction stops. This usually takes about 5 minutes. Once the reaction is done, you now have sodium carbonate. Cover the pot of carbonate with a lid and remove it from the heat to cool. The lid will prevent moisture in the air from re-entering the carbonate as it cools.

3. Prepare a hot water bath and measure your solvent

Heating up solvent in a hot water bath on a magnetic stirrer.

While your carbonate is cooling, it’s time to start warming up your solvent in a hot water bath. Place your Pyrex measuring cup on your magnetic stirrer and fill it a little less than halfway with hot water. I like to use an electric kettle because it quickly brings the water to a boil and keeps the water hot for the water wash.

If you dont have an electric kettle you can boil a pot of water on your stove for use. However, I highly recommend the electric kettle to keep things running smoothly and to keep your water at a consistent temperature during the water wash process. Once your hot water is in your measuring cup and on your magnetic stirrer, you need to measure out your solvent.

Determining how much solvent you need depends on how much spice you plan to clean up. You will want to use 100ml of solvent per 1 gram of DMT. If you have an uneven amount of DMT to clean like 1.6 grams of DMT to clean, you will round the amount of solvent up. In this example, I’m cleaning 1.6 grams of DMT. using a beaker, I’m going to measure out 200ml of heptane.

After measuring out the solvent in a beaker, place a magnetic stir bar into your solvent and place the beaker of solvent in your hot water bath on the magnetic stirrer. Turn the magnetic stirrer on medium-low to prevent solvent splashing, and cover the top of the beaker with a glass plate to contain the fumes. You want to mix your solvent for about 5 minutes to allow the bath to heat the solvent.

Water washing the DMT

1. Prepare the first water wash solution with carbonate and salt

While the solvent is heating up, use this time to prepare your first water wash solution. Using one of your mason jars, place a magnetic stir bar in your jar and add equal parts of water to the solvent you’re heating up. Since I’m using 200ml of solvent, I’m going to use 200ml of distilled water. With the water measured out, add ½ teaspoon of sodium carbonate to your water and 1 tablespoon of pickling salt to the water and mix thoroughly until dissolved.

By adding the carbonate to the water, the pH of the water will rise to 9.5 to 10. With the water being a higher pH, it is going to act like a magnet for any base that may be present in your DMT and boost the cleaning performance of water-soluble impurities. The Salt will allow your solvent to separate from the water quickly and will protect against emulsions during the mixing steps.

2. Add the DMT to the water wash solution

Now that your first water wash solution is ready, the DMT in your solvent should be dissolved. You may see some solids remaining but that is normal. The solids are micro bark material that you dont want in your DMT. With your DMT fully dissolved, pour your DMT solvent into the first water jar you prepared with the carbonate and salt.

Loosely fit a lid over the jar to contain the fumes. Do not tighten down the lid because the heat from the hot water will cause pressure to build which can led to a broken jar. The lid is simply to contain the fumes and allow any pressure to escape from under the lid.

Remove the Pyrex measuring cup from the magnetic stirrer and place your water wash jar on the stirrer. Turn the magnetic stirrer on medium-high and allow your solvent to mix with the water for 30 seconds. After 30 seconds, turn your stirrer off and allow the solvent and water to fully separate. You will know when the solvent is fully separated because no solvent bubbles will remain in the water. Full separation usually takes about 5 to 10 minutes.

3. Prepare the second water wash jar

While waiting for your solvent to separate, use this time to prepare your second water wash jar. Using another mason jar, fill your jar with equal parts water to solvent. Again, since I’m using 200ml of solvent I’m going to add 200ml of hot water. You want your water to be really hot because this keeps your DMT dissolved in your Solvent during the duration of the wash.

If the water is too cold, I’ve noticed pre-mature crystal precipitation which can lead to an unnecessary loss of yield. This is why I strongly recommend an electric kettle because it allows you to have very hot water on demand.

Add the water to your jar as well as another magnetic stir bar. Then add 1 tablespoon of salt to the water and mix until dissolved. Do not add any carbonate to this wash! Carbonate is only needed for the first water wash, the remaining two washes are just hot water and salt to protect against emulsions. Whatever carbonate you have remaining, place it in an airtight container and save it for future clean-ups.

4. Siphon the solvent from the first water wash

After your second water wash jar is set up and your solvent has fully separated itself from the first water wash, it’s time to siphon out your solvent into your second water wash jar. Using your pipette, begin to siphon off the top layer of solvent into your second water wash jar. Take your time and siphon carefully to avoid sucking up any of the water. You want to siphon as much solvent as you can without sucking up any water because we dont want to carry the dirty water over to the clean water in the second wash.

You will notice that you will not be able to get all of the solvent from the first wash jar. This is perfectly fine because, after all of the water washes, you are going to combine the leftover solvent layer from each jar into a smaller jar to collect the remaining solvent. Cover the remaining solvent you couldn’t recover with a lid and set it off to the side for later collection.

5. Mix the second water wash solution

After siphoning as much solvent as you can from the first jar into your second washing jar, place a loose-fitting lid on your jar to contain the fumes and place it on your magnetic stirrer on medium-high speed. Mix the solvent and the washing solution for 30 seconds, then turn off the stirrer and allow the solvent to separate again.

While the solvent is separating, prepare your last washing jar. Again measure out equal parts of hot water to the solvent being used, add a magnetic stir bar and 1 tablespoon of pickling salt then mix well until the salt is dissolved.

6. Siphon the solvent to the final water wash jar

When the solvent from the second water wash is fully separated, use your pipette to siphon the solvent into your final washing jar. Again be very careful not to suck up any of the dirty water. Collect as much solvent as you can and add it to your final washing jar. Whatever solvent you can’t collect, cover it with a lid and set it off to the side to combine with the leftover solvent from the first wash.

Place your final washing jar on your magnetic stirrer at medium-high speed for 30 seconds and then turn off the stirrer and allow the solvent to separate for a final time.

7. Collect the solvent for freeze precipitation

While the solvent is separating, set up your casserole dish to collect the solvent after it has separated. By this point, you’ll notice that the solvent is a lot cleaner than it was in the first initial wash. This is a great sign that your wash worked and the solvent should now look clear and yellow.

Once the solvent is fully separated in your final jar, siphon off as much solvent as you can into your casserole dish. It’s very important that you dont suck up any water in this step especially because if water is present in your casserole, the water will freeze and when it melts, it can dissolve your DMT crystals while it’s drying. Get as much solvent as possible and leave a little layer behind as you did in the previous steps.

Once you’ve collected as much solvent as you can without collecting any of the washing water, cover your casserole dish with the lid or foil and set it off to the side. Do not put it in the freezer yet because we need to collect the tiny solvent layers left over from our previous washes to add to the casserole dish.

8. Collect the leftover solvent from previous water washes

Pour the leftover solvent from the previous washes into 1 jar and allow it to separate. Once separated, siphon as much solvent as you can into a smaller beaker or shot glass. This is a safety step taken to ensure you dont accidentally put water into your precipitation dish. You will not be able to get all of the solvent. Again the layer gets too thin to collect it all. This little bit left behind will affect your return yield a little bit but not by a significant amount to stress about.

Collecting the remaining solvent from all water wash jars.

Once you’ve siphoned as much as you can into the beaker or shot glass, inspect the beaker to make sure no water is present. Once you are certain that none of the washing water is in your beaker, then you may add the remaining solvent to your dish.

9. Freeze the solvent and collect your crystals

After collecting all of your solvent you are going to freeze precipitate the solvent in your freezer for 24 hours like you did in your first initial DMT extraction. After 24 hours remove your dish from the freezer and pour off any extra solvent present in the dish. You will notice that the DMT precipitates into larger crystals this time because it’s cleaner than it was in the initial extraction.

Large DMT crystals after cleaning that are ready to be dried and collected using a small fan.

Prop the dish against a wall, upside down, and use a small fan to blow indirectly at the dish to help speed up the evaporation of any remaining solvent. You will know when the crystals are dry because there will be no smell of solvent. Once they are fully dry, you are ready to collect them using a razor to scrape them up.

In my example, I started with 1.6 grams of DMT and after the sodium carbonate water wash my final weight was 1.4 grams. This loss in yield is from all of the impurities removed and the tiny layer of solvent I was unable to collect at the end. However, this loss in yield is fine because it was stuff I didn’t want in my final product anyway.


If you made it this far, congratulations on completing a sodium carbonate water wash. This process is very simple and leaves you with a squeaky clean DMT that is now ready to enjoy. Your DMT is safe for consumption and free of any impurities or base that may have worked its way over in your initial extraction.

With your final product ready to go you can enjoy it with the method of your choosing or even make it into a vape juice for carts and mods. I hope this write-up helped clear up any questions you had and gave you the confidence to conduct your water wash.

4 thoughts on “Water Wash Tek: Clean DMT With Sodium Carbonate”

  1. I like to add this step to wash from each pull instead of after. Thanks for the tip on sodium bicarbonate, I was just using warm saline the ph makes a little more sense. To save a precipitation seems effective right from the pull. Simplifying the meticulous siphoning adding a catch phase. Very white and clean batches. Thank you

    1. You can do that but personally I prefer to precipitate my crystals first because I want to wash the crystals that are dissolved in fresh solvent and not solvent that has been sitting in the base layer during the duration of the extraction. If you freeze the crystals first and collect them, you’re only washing away any base that may have stuck to the crystals rather than cleaning base out of crystals and the solvent that was in your base.
      In other words, by removing the solvent used to extract the DMT I get a lot of the base out immediately and have less to clean which means that you have that much less of a chance of base making it through your water wash.
      By adding crystals to fresh solvent, you’re cleaning what little base may have stuck to the crystals, which makes it less likely that base will make it into your final crystals.
      It’s easier to clean something when the thing you’re trying to remove is less concentrated, and most of it is removed beforehand.
      So yes, it’s faster and will save time, but in my opinion, risks the quality and effectiveness of the cleaning process.
