Here is how to use acetone to clean metal surfaces before painting.
Over time, your metal can get affected by rust, oil, dust, or grease. This can result in the peeling of paint, among other physical damages.
To give your metal a new look, you’ll need to repaint it. Until then, you must take vital precautions to ensure the paint adheres properly and lasts.
Your first step will be to clean and prime the surface for the new paint. If not, the paint won’t stick as expected. Acetone cleaning will wipe away dirt and residue from the surface.
Plus, it will prevent peeling when the new color is added later.
Acetone Metal Cleaner
Now, there’s lots of contemplation as to whether or not acetone can be used for such cleaning. But can this solvent be used for such an operation?
To get an answer to this question, you’ll need to read on. This article will focus on using acetone to clean metal before painting.
But before hitting the nail on the head, let’s briefly review this solvent.
What You Should Know About Acetone
Acetone is a powerful solvent that can dissolve oil, grease, and other contaminants on surfaces. The chemical is clear, colorless, strong, has a sweet odor, and is a highly flammable liquid.
It contains a carbonyl group bonded with two alkyls. You can use it to break down various materials, including rubber and plastic.
Acetone to clean metal before painting is a renowned cleaning technique. It ensures the final coloring adheres appropriately to the surface without any issues.
We refer to peeling or bubbling. Furthermore, its cleaning capabilities make it a perfect solution for addressing stubborn stains.
How to Use Acetone to Clean Metal Surfaces Before Painting
Below is a step-by-step guide on how to use this chemical to clean rusted metal. Going by these procedures will award you with an excellent result.
Sandpaper the Metal Surface
Usually, old metal is composed of loose particles such as rust, debris, and old paint. Before anything else, you’ll need to remove all of these particles.
Adding a new coat of paint to clumps of dirt can reduce the adhesion rate. Therefore, you’ll need to use sandpaper or a wire brush to remove any debris on the surface.
Clean the Surface Again With a Damp Cloth
After removing debris, wipe the surface down with a damp cloth or sponge. Using a wet cloth removes any leftover dirt clinging to the metal surface. While you do that, avoid soaking the metal.
Otherwise, it will increase the rate of rusting if left unattended.
Apply Some Acetone and wipe the surface.
Now, pour a small quantity of acetone into a container like glass or plastic.
Next, you use a clean, soft cloth or sponge and dip it into the solution. Ensure the fabric is properly saturated and wipe the surface. You can apply gentle pressure to remove dirt, grease, or oil.
Repeat the process multiple times to ensure the surface is clear and clean. Meanwhile, it’s not advisable to wear skinny clothes for cleaning.
That’s because they can dry out quickly and most likely catch fire. Moreover, you’re to wipe and wash in one direction and avoid putting too much pressure on it.
Clean Out the Leftover Acetone
Leaving this solution on the metal for an extended period after cleaning is not advisable.
It can damage the surface. Therefore, you’ll need to clean the surface with a damp cloth. Ensure the excess solvent is properly cleaned.
Allow the Metal to Get Dried
Once the surface is explicitly clean, allow it to dry completely before applying paint.
Usually, spraying paint on wet metal surfaces can lead to rust formation underneath the paint film. In other cases, it can lead to bubbling in the coating due to trapped moisture.
Perks of Using Aceton to Clean Metal Before Painting
Several benefits accompany using this solvent to clean metal surfaces before painting. Firstly, the chemical addresses contaminants like oil, grease, and dirt.
These elements often interfere with the adhesion of paint. Secondly, the solvent evaporates quickly. This means it won’t leave any residue behind to prevent the color from adhering correctly.
Furthermore, acetone is inexpensive and easy to get on the market. This makes it a perfect solution for cleaning metal before painting. Most importantly, it’s water soluble and safe to use.
Although it can be toxic, its toxicity is lower than other chemicals.
Dangers of Using Acetone for Metal Cleaning
Despite being a highly effective chemical, it also has some drawbacks. Firstly, the substance is highly flammable, which will require extreme care.
It’s not advisable to use this solvent in an airtight space. Additionally, do not use the substance in areas with heat sources or flames.
Furthermore, acetone can be harsh on some types of surfaces. For instance, it could damage metals that are prone to corrosion. It can also strip away protective coatings or finishes that may be on the metal surface.
Safety Guidelines of Acetone Metal Cleaning
You are to take precautions when using this solvent to clean metal before painting would be best. Remember, this solution is highly flammable.
Therefore, you should avoid heat sources, flames, or sparks. When using acetone for cleaning, ensure your work area is adequately ventilated.
Additionally, you should wear your safety gear when handling such chemicals. Wear hand gloves and eye protection to prevent skin irritation and eye damage.
Alternatives for Acetone to Clean Metal
Having highlighted the dangers of this chemical, you may not be comfortable using it. In this regard, you’ll need to resort to other alternatives.
Luckily, there’re other methods you can use to clean such surfaces without using acetone. They include soap and water, sandpaper, vinegar, and mineral spirits.
All these alternatives are effective and cheap.
They’re also less toxic and can be used in areas with a source of heat and flame. However, not all of these substances can be found in hardware stores.
You must prepare the metal surface before repainting. It will make the surface look smooth, clean, and durable. One way to prepare such a surface is to use acetone to clean dirt and debris.
The solvent is effective and will ensure your operation goes smoothly.
However, there’re dangers associated with the use of this chemical. Therefore, you must abide by the safety guidelines described above.
