While isopropyl alcohol is a commonly recommended solution for removing old thermal paste, it is not the only option. Some people suggest using a dry paper towel, tissue, or towel/rag. Others recommend using a lint-free cloth with hand sanitizer, or a cloth with nail polish remover, though this may not be as effective as alcohol. If you do use a liquid cleaner, ensure that the surface is completely dry before proceeding.
How to remove old thermal paste without alcohol
| Characteristics | Values |
|---|---|
| Materials | Paper towel, q-tips, old t-shirt, microfiber cloth, coffee filter, dry tissue, towel/rag, water |
| Steps | Scrape off the majority of the pad with a credit card or similar plastic piece. Use a q-tip with water to clean up the rest. |
| Precautions | Avoid using toilet paper, facial tissue, and most paper towel brands as they can leave behind lint which inhibits heat transfer. Ensure surfaces are completely dry before proceeding. |

What You'll Learn
Use a paper towel or tissue
If you do not have access to alcohol, a paper towel or tissue can be used to remove old thermal paste. It is important to use a dry paper towel or tissue, as water can be detrimental to the process. The paper towel or tissue should be tough to avoid tearing.
To begin the process, detach the heatsink or waterblock from the CPU and remove the CPU from the motherboard. Place both on a clean, flat working area with the thermal surfaces facing up. Next, use a paper towel or tissue to wipe away the thermal paste. It is important to wipe from the inside out to prevent the paper towel or tissue from snagging on the corners and leaving behind fibres.
This method may not remove all traces of the thermal paste, but it will remove the majority of it. It is important to allow the surface to dry completely before reattaching the CPU cooler and reapplying new thermal paste.
It is recommended to use a lint-free cloth, such as a microfiber cloth, to avoid leaving behind any fibres that could inhibit heat transfer. However, in the absence of a lint-free cloth, a paper towel or tissue can be used with caution.

Try a lint-free cloth
If you are looking to remove old thermal paste without using alcohol, a lint-free cloth is a good option. It is important to ensure that the cloth is made of a material that will not leave behind any lint or residue, as this can inhibit heat transfer and affect the performance of your device.
Microfiber cloths are a popular choice for this task, as they are designed to be lint-free and are effective at removing thermal paste. You can also use a cloth made from an old T-shirt, as long as the material is not too fuzzy or prone to leaving lint. Coffee filters, which are designed to be lint-free, can also be used.
When using a lint-free cloth to remove thermal paste, it is important to be gentle and to avoid applying too much pressure. You may need to work the cloth into the crevices of the device to remove all the paste, but be careful not to scratch or damage any sensitive components.
While a lint-free cloth can be effective at removing thermal paste, it may not be as thorough as using a liquid cleaner. Some residual paste may remain, so it is important to inspect the device carefully after cleaning and remove any remaining paste with a cotton swab or cloth before applying a new layer of thermal paste.

Cotton buds with water
Firstly, water is a conductive liquid, and using it near computer components could potentially cause damage if it gets somewhere it shouldn't. Additionally, water may not effectively dissolve the grease base of the thermal paste, leading to smearing and spreading rather than removal.
If you choose to use cotton buds with water, it is crucial to ensure that all surfaces are completely dry before proceeding with any further steps. Leaving the components to air dry for an extended period may be necessary.
However, it is important to note that other methods and solutions are generally recommended over water. These include using a tough paper towel, a lint-free cloth, or cotton buds with an alcohol-based solution such as isopropyl alcohol. These alternatives can provide more effective and safer results when removing old thermal paste.

Nail polish remover
Using nail polish remover to clean thermal paste is not recommended by many, as it may harm your computer components. Acetone derivatives found in nail polish remover can be harmful, and other ingredients such as oils should be avoided.
However, some people have used nail polish remover to clean thermal paste without issue. If you do decide to use nail polish remover, it is best to use a product that is pure acetone, as other ingredients in nail polish remover may negatively impact the effectiveness of the new thermal paste.
To use nail polish remover to clean thermal paste, start by using a dry Q-tip to remove most of the old paste. Then, dampen another Q-tip with nail polish remover and use it for a final clean. Be sure to visually inspect for any stray pieces of lint before reapplying new thermal paste and assembling your computer.
It is worth noting that there are other effective methods for removing thermal paste that do not involve nail polish remover. Some people have had success using dry paper towels or baby wipes to remove old thermal paste without any liquid cleaners. Others have suggested using a dedicated wipe, such as the Kooling Monster KLEAN-01, which is designed specifically for removing thermal paste and comes with protective gloves to keep your hands clean.

White spirit
To use white spirit for removing thermal paste, it is recommended to first scrape off the majority of the paste with a plastic tool, such as a credit card, being careful not to scratch the base of the heatsink. Then, use a cotton bud or paper towel dipped in white spirit to wipe away the remaining paste. After cleaning, ensure that the CPU is completely dry and free of any residue before proceeding with any further steps.
It is worth noting that while white spirit can be used as an alternative to alcohol, it may not be as effective in removing thermal paste. Isopropyl alcohol, also known as rubbing alcohol or surgical spirit, is preferred because it evaporates quickly and leaves no residue. A high concentration of 90% or higher is recommended for effective cleaning.
Some people have suggested using other alternatives to alcohol, such as electronic contact cleaner, which can be found at hardware and automotive shops. Others have mentioned using kitchen roll, paper towels, or soft cloths to mechanically remove thermal paste without the need for additional solvents. However, it is important to avoid using tissues, facial tissues, or paper towels with high lint content, as they can leave behind fibres that can interfere with heat transfer.
