Cleaning your oil painting with picture cleaners demands time, effort, and concentration, as a silly error can lead to substantial damage.

Also, your painting will be protected from the dripping or spillage of picture cleaners throughout the process.
It is suggested that you create a soft and firm support underneath the canvas so that while applying the cleaners, it creates a strong grip and does not slide, damaging the canvas.
Pour the picture cleaner into a jar; it could be Winsor & Newton Artists’ Picture Cleaner.
Then dip the swab and dampen it until the edge turns liquid, though it shouldn’t be dripping.
Start rolling the swab across the canvas; do it slowly but firmly.
Repeat the process, but make sure you don’t overdo as much as it takes to take the dirt off the canvas.

What To Never Use To Clean An Oil Painting
Paper Towels
Sometimes it is not about intentions or techniques but about the product that you use to clean an oil painting.
They don’t work in your favor because they were never meant to act like that.
One such oil painting cleaning product, which was promoted oftentimes, was paper towels.
Paper towels tend to take a significant amount of paint off your canvas if not used properly.
The scenario can be different if you gently use it across the surface to catch the dust.
Oftentimes, it is used to take out dirt that has formed on the colored part, and in order to wipe it out, we press the paper towels harder against the surface.
Instead of picking up dust and dirt, it leaves its own pieces, forming grains on the surface of the oil painting.
This attempt rips off any textures and certainly pulls some of the paint away.
Feathers or Stiff Brushes
Feathers and stiff brushes are considered great products for oil painting dusting, but they have barbs, which can create an issue.
What if the barbs strike the painting, especially on those parts covered with dark hues?
The chances are very high that it may take some paint off because of its sharpness.
Only an unprofessional or novice can use them for dusting, as they don’t help in any way.
You can either pick up soft bristles, dusters with no features, or fluffy ones that can dust your oil paintings.
Water solution
Water or any water based solution can’t be used for cleaning an oil painting.
It can negatively react to it, and its effect can be detrimental—you should avoid using it at any cost.
If used, it can reduce the intensity of colors and make the art lifeless.
If overused, it can seep from one part of the canvas to another and peel the color off.
Flake the pigments and perhaps lose their grip on the wooden canvas.
The common issue that can occur is that it can shrink and separate the color and create a wet section, spreading the color across the canvas.
Vinegar, Lemon Juice, Alcohol or Household Detergents
In most DIY oil painting cleaning projects, these products are commonly endorsed but, in reality, have drastic negative effects.
Pouring or rubbing some of these can smear the paint or peel the paint off.
These are acidic in nature, which has immediate effect on any color of oil pigment and professionals recommend because they are easily available at any home
You can instead use saliva, but avoid these cleaners.
Baby Oil
Baby oil can produce a sticky layer on the surface where it is applied.
It is seen as adding a shiny look, making the color look more vibrant and prominent.
It does make it look brighter and glossy, but as time goes on, it catches dirt and dust faster.
Baby oil is never used to get grime off the canvas; perhaps dust can be removed to some extent, but eventually it tends to catch more dust or airborne dirt.
Bread
Breads is often used to dab on the surface with the intention of getting unwanted dust removed from the oil painting
Although some dust gets off, it leaves some minuscule pieces of itself.
This can also leave crumbs on the surface if not brushed off properly, and while reapplying the coating of varnish, it can create its own layers by mixing up with the existing pigments.
It results in the distortion of colors and textures and with time, it attracts airborne particles and contributes to mold growth
These are the products you need to avoid when cleaning an oil painting.

When To Seek Professionals To Clean An Oil Painting
It is suggested that you seek professionals or art restorers when in doubt.
You can’t start cleaning your oil painting right away.
You need to consider a few things and plan your approach.
Whether it is flaking, cracking, or has yellowed varnish, you can have it removed on your own.
As an art owner, you must ensure that whatever you plan does not go overboard, as a slight change or incorrect technique may cause irreparable damage.
It is suggested that you carry the right oil painting cleaners and follow the instructions carefully.
Here are some reasons that tell you that you need an art restoration specialist.
- Shows cracking
- Flaking and peeling off
- Forms an unnatural layer of dirt
- Excessive mold and stickiness
- Unsure about results
- Lack of time
- Lack of knowledge
How To Keep Your Oil Painting Away From Dirt In Advance
Many reasons contribute to the formation of grime, making an artwork look dull and shabby.
Whether you have cleaned your oil painting by following the above shared techniques or just mounted a new painting, here’s how you can keep your oil painting away from dirt in advance (Two Important Tips).
1. Routine Dusting
Routine dusting is a must and can also be useful if your oil art doesn’t have a stubborn sticky layer or unfixable dirt.
Dusting your painting can have a significant effect if done properly.
The bristles of the brush shouldn’t be sharp; they should be soft because barbs can cut some paint off and hamper its essence.
You can even start from the bottom or top, or perhaps tilt the painting upside down (towards you) and start brushing from left to right in a way that dusts it off in the air.
It is suggested that you sweep the canvas attentively and not indulge in an abrasive movement to alter it.
Once it is done, you can add a coat of varnish, which extends its shelf life.
2. Correct Placement
The location of the painting determines its future.
If it is mounted in a cramped place, it will catch up the dirt presently because of the corners, or if the space between two pieces of furniture is less, it’ll accumulate spiders and dust very early.
Also, the painting should be kept far away from direct sunlight or a source of moisture, as the rays can immediately affect the pigment.
It is recommended to keep it away from steam or smoke; it can yellow the art very soon.
Keep it away from open windows and air, as outside elements can cause the formation of the grime.
Mostly, it is kept in an open space where people can see it and rejoice in seeing it.
By following these techniques, you can keep any artwork—custom, pet, or family portrait—away from potential threats.
The Bottom Line
When you take up the job of cleaning your oil paintings, you learn several things.
For example, the nature of colors used in the art, different oil painting cleaners and techniques, and others.
Cleaning an oil painting on canvas is a painstaking process. But with each attempt, you get closer to mastering the art of cleaning oil paintings.
Whether you own a cat picture, a horse portrait, or a reproduction of famous art, you need to put it down on a flat surface and clean it promptly.
The above-shared process helps you remove dust, dirt, and all sorts of grime, keeping your art evergreen
