How to Get Oil to the Bottom of a Cart

If you’re a vape enthusiast, you might have encountered the frustrating situation of having oil stuck at the top of your cartridge, leaving the bottom dry and unusable. This can be a common problem with vape carts, and it can lead to wasted oil and a less enjoyable vaping experience. In this article, we’ll explore several methods to get the oil to the bottom of the cart, ensuring you get the most out of your vaping sessions.

How to Get Oil to the Bottom of a Cart

Vape cartridges are a convenient and discreet way to enjoy your favorite oils and concentrates. However, sometimes the oil can get trapped at the top of the cartridge, away from the heating element. This can happen due to various factors, such as the oil’s viscosity or improper storage. In this article, we’ll provide you with practical solutions to ensure your oil flows smoothly to the bottom of the cart, optimizing your vaping experience.

Why Oil Gets Stuck in the Cartridge

Before we delve into the solutions, it’s essential to understand why oil might get stuck in the cartridge in the first place. Viscous oils, especially in colder temperatures, tend to move more sluggishly, making it difficult for gravity to pull them down to the bottom. Additionally, improper storage, such as keeping the cart on its side, can also cause the oil to accumulate at the top end. Now, let’s explore the solutions.

Storing the Cart Upright

One simple solution is to store your vape cart upright. By doing so, gravity will naturally bring the oil down to the bottom, where the holes leading to the heating coil are located. This way, the oil will be readily available for vaporization when you use your vape pen.

Submerging the Cart in Hot Water

To encourage the oil to flow down, you can try submerging the cartridge in hot water. Place the cart in a sandwich bag, remove all the air from the bag, and then submerge it upright in a cup of hot water. The heat will help loosen the oil, allowing it to run down to the bottom of the cartridge.

Using a Heating Pad

A heating pad can also be employed to loosen thick concentrates. By gently applying heat to the cartridge, the oil will become more fluid and move to a more localized area within the cart, increasing the chances of it reaching the bottom.

Heat it Up with a Blowdryer

Using a blowdryer is another effective method to get the oil flowing. Warm up the cartridge with the blowdryer, and as the oil heats up, it should start flowing around the cartridge. You can then work it back towards the heating element of your vape pen.

Making a Supercharged Joint

For those who also enjoy traditional smoking methods, you can make a supercharged joint by pouring the leftover oil from the cart onto your next blunt. This way, you can maximize the use of your oil and enjoy it in multiple ways.

Using Small Tools to Separate the Pieces

If the above methods don’t work or if you prefer a hands-on approach, you can use small tools like a flat-head screwdriver or needle-nose pliers to gently separate the different pieces of your cart. By pulling and twisting, you may dislodge the oil and direct it to the bottom.

Watching YouTube Tutorials

The internet is a vast resource, and you can find several YouTube tutorials demonstrating how to get oil out of a cart effectively. These tutorials may include methods like submerging the cart in hot water, using a syringe to extract the oil, and more.


With these methods, you can ensure that your vape cart’s oil flows smoothly to the bottom, making the most of your oil and enhancing your vaping experience. Remember to store your cart upright and consider using external heat sources like hot water, heating pads, or blowdryers to encourage the oil to move down. Additionally, you can explore creative methods like making a supercharged joint or using small tools to dislodge the oil. By doing so, you’ll maximize your vaping pleasure and reduce oil wastage.
