What Are The Signs That You Really Need To Clean An Oil Painting?
Oil painting is made from one of the most versatile and commonly used mediums—Oil paints.
These paintings can last for centuries; but like everything, they’re subjected to aging.
The surface of an oil painting can accumulate dust, grime, molds and can become stained.
Below are a few signs that you should look for before cleaning oil painting:
- A dull look of the painting.
- Layers of dirt or grime.
If your artwork has flaking paint, cracks, or is warped; it’s a strong sign of aging.
Solution? Don’t try to clean artwork yourself. Take it to Art Conservators.
Also, evaluate the value of the painting before starting the cleaning session. If your painting is a thousand dollars worth piece or is antique, we recommend you don’t go for this DIY oil painting cleaning project.
Instead, go to the professionals! They’ll be able to restore your painting without causing any damage to the artwork.
Now that you’ve decided to clean oil paintings at home, let’s jump right into it.
3 Foolproof Ways To Clean An Oil Painting At Home
Get ready before you start cleaning an oil painting.
- Gather your supplies:
A soft brush, hand gloves, cotton swabs, lights, magnifying glass, easel (optional).
- If the painting is framed, you have to carefully take the painting out from the frame.
- Choose a flat and stable surface where you can keep the painting.
- Cleaning painting will take time. So choose a comfortable spot where you’ll be able to focus.
- Use ample lighting or use a natural source of light.
1. Dry Brushing
Dry brushing is the most preferred method to clean paintings at home.
It involves dusting the painting to get rid of dust and other particles that might have accumulated on the surface of the painting.
Follow these steps:
A. Place The Painting On A Flat And Stable Surface
There’s no problem if the painting is attached to a sturdy position like a wall, but it is beneficial when you keep it on a flat surface for cleaning.
The reason for this is that keeping the painting on a flat surface will let you see the painting from a different angle.
This will let you discover any other flaws your painting might have and will give you more scope for cleaning.
A stable surface is preferred as it will let you work efficiently. Use ample lights so that you can get a clear view of the painting.
B. Choose A Soft Brush
Choosing a soft brush is the key to effectively cleaning oil paintings. Otherwise, you risk damaging the artwork.
When you select the brush, move your fingers over the bristles to make sure that they are soft.
✔ Sable brushes are a great choice for this task.
✖ Feather brushes should be avoided as they can scratch paintings.
Also, make sure that the brush is dry.
A thumb rule: Bigger the painting is, the larger your brush should be —unless you want to spend your whole day brushing the dust off the painting!
C. Dust A Small Section Of The Painting
Now that you’ve chosen the perfect brush for cleaning an oil painting, it’s time to start the process!
Start dusting from the top corner. Work on a small section of the painting with soft up-and-down brush strokes and make sure to work on a few inches at a time.
Slowly move down until you reach the bottom of the painting.
You can use other brushing motions like left-right, circular; but we recommend you to go with up and down motion. This will ensure that dust is removed instead of being tossed around.
Pro-tip: When dusting, always work on a small part first. This will let you see the difference between a cleaned and non cleaned part.
D. Continue Dusting Deliberately
Now, complete the process!
Start cleaning in small sections until every centimeter of the painting is covered.
You can use a magnifying glass to your advantage.
Remember that soft and light strokes are essential, or else you may damage the painting.
Warning sign: if the paint flakes off, stop! It’s a sign of aging and the best you can do is take the painting to a professional art restorer. Don’t attempt to clean such an oil painting yourself, or it might get damaged.

2. Cleaning With Saliva
I know it sounds so odd, but cleaning with saliva is a safe and the best way to clean oil painting at home.
It’s weird to imagine how your saliva can be used to clean an oil painting, but professionals have been using this technique for ages.
Our saliva has enzymes that are strong enough to break down dirt and grime but are too weak for breaking down the paint.
If you’re wondering how to clean an oil painting with saliva, just read on!
A. Moisten The Cotton Tip With Your Saliva
Take a cotton swab and roll it on your tongue so that it is damp with your saliva.
Make sure that the cotton tip is moist and not dripping with your saliva. If it is dripping, dab it with a piece of cotton.
Always choose high-quality cotton swabs as they are softer than regular cotton swabs.
Pro Tip: Avoid eating/drinking (except water) for about 20 mins before you start cleaning an oil painting with saliva as food can mess up with the enzyme activity of your saliva.
B. Do A Patch Test
It is always better to do a test on a small area before proceeding further.
Take the damped cotton swab and swipe a small portion of the painting. Wait for a few minutes to see how the painting is reacting to saliva.
You’d be able to determine if the saliva is cleaning or hurting the painting.
C. Swab In Small Sections
Once you’re assured that this method is working out, it’s time to swab the entire painting!
Work inch by inch with small gentle up-down dabs. You have to make sure that you don’t apply too much pressure.
D. Switch The Tips!
If the tip is worn out or dirty, switch to the other side of the swab. Because you wouldn’t want to spoil your artwork by using a dirty cotton tip.
Also, using a fuzzy cotton tip can smudge the dirt back to the surface of the painting.
Tip: Avoid using a cloth or other soft material for this method, as the cloth can be abrasive and scratch the surface.
This technique is time-consuming but is one of the best ways to clean painting at home.
3. Seek Help Of The Experts
Probably the best way to clean an oil painting— always seek the help of a professional art restorer.
The surface of the painting is delicate and there’s no margin of error when you clean a painting.
One wrong move and your precious painting is ruined forever.
That’s the reason why you should consult a professional conservator or restorer before attempting to clean old oil painting at home.
There are two ways to do it.
A. Take The Painting To Art Conservator Or Restorer
If you see flaking paint or cracks in it, it’s a strong sign of aging. What it means to you is that you should not attempt to fix or clean the oil painting by yourself.
Take the painting to experts.
Art conservators or painting conservators are the experts who understand the chemistry behind the painting and materials.
So, they are able to restore and recreate damaged or old paintings precisely.
These experts are skilled in their field. They use high-end equipments, chemicals, and follow different conservation processes for every artwork.
So, once you send your painting to an art restorer, be rest assured that your painting is in safe hands.
B. Call The Experts
So you don’t want to take the oil painting to a conservator and want to do the magic yourself?
Cool. You totally can! You can use the methods mentioned above, or you can ask the experts for help.
Here’s how it can be done:
- Consult an art conservator or restorer and ask them how to clean an oil painting at home. You can ask them for tips or ways on how to clean a canvas picture.
Remember This: Many art conservators will tell you to bring the painting to the studio to get it restored. An art conservator will be able to clean or restore your painting without damaging the piece.
- Many art restoration companies sell cleaning products that are specifically designed to clean paintings. You can spend a few bucks to get those products.
Art Restorer Or Art Conservator— Whom Should You Choose For Cleaning Your Oil Painting?
If you look up the internet, people use both terms interchangeably.
Although they belong to the same stream, there is a thin line that separates them.
An art conservator works on slowing down the aging and preserving the quality of the painting, while an art restorer focuses on restoring the painting to its original form.
Many art conservators have formal training in restoring the painting.
So before you choose an art restorer or conservator, redefine your goal first.
Do you just want to clean an oil painting? Do you want to restore it? Or do you want to just slow down its aging?
Defining the goal will let you choose the correct professional for your painting.
Before jumping to other techniques of how to clean a canvas painting, it’s time to address a debatable question:
“Can I Use Water For Cleaning An Oil Painting?”
It’s a widely asked question. People on the internet will say that it’s okay to clean an oil painting with a solvent like water.
But let me ask you, “is the surface of your oil painting a bathroom floor?”
I know it may sound rude, but in reality, an oil painting is a precious artwork that deserves special care.
Although oil paint when dried is water-resistant, it doesn’t mean that it won’t react with water.
When you clean an oil painting with water, it can change the dimension of the fabric (canvas) and may wash out the paint if the painting is aging.
Water can be seen as a home remedy for cleaning oil paintings, but what most people are unaware of is that water can seep the dirt into the pores and stain the painting.
Your simple gesture of cleaning an oil painting at home can ruin the painting more.
Apart from using water, you’ll find many other techniques that netizens recommend for cleaning oil paintings on canvas.
7 Common (But Not Recommended) Methods Used To Clean An Oil Painting
There’s a high chance that when you read some of the blogs on how to clean an oil painting, you would come across some fancy cleaning methods using water, lemon, bread, potato, and whatnot!
The problem with these methods is that they are unreliable.
These techniques may work and you’ll be left with a clean painting, or they won’t work and your painting will be destroyed forever.
And experts believe, latter is true.
For the sake of information, we are mentioning some common methods that may help you clean old oil painting.
If you value “quick fixes” more than your painting, then the following list is just for you.
And if the painting is precious to you, stick to dry bruising, cleaning with saliva, or consider taking the painting to experts.
Word of caution: Do it at your own risk.
1. Using Water And Lemon Juice
Although it is true that mixing lemon juice and water makes a good cleaning agent, we should know that we aren’t cleaning any appliances here.
Lemon juice and water can react with oil paint and cause undesirable effects.
2. Cleaning Oil Paintings With Potato
Cleaning an oil painting with potatoes can be the dumbest thing anybody can do.
Starchy food can leave a residue which can cause molds to grow on the painting.
3. Using Soap Water
Water, whether with soap or lemon, is not recommended for oil painting cleaning.
As said earlier, water can do more harm than good to your oil painting.
4. Cleaning With Baby Oil
Many believe that rubbing baby oil can make the painting shine and make the colors stand out.
But the problem with it is that the baby oil can make the surface sticky, which in turn can attract more dust.
5. Using Bread To Clean Oil Paintings
How to clean an oil painting with bread?
You just don’t!
Some online amateurs will tell you to wipe the surface of the painting with a loaf of bread. Don’t fall for this trap ever!
Using bread can leave tiny crumbs on the painting which can support the growth of molds (fungus).
6. Cleaning With Calcium Carbonate
Another dumb way to spoil your painting is using calcium carbonate to clean it.
The method involves dissolving calcium carbonate crystals in water (duh!) and dabbing the painting with soaked cotton balls.
7. Using Vinegar or Alcohol For Canvas Painting Cleaning
Cleaning oil paintings with vinegar is a bad move. Using vinegar (diluted or undiluted) will react with the oil painting and spoil it.
Similarly, if you use alcohol, it will remove the oil paint from the canvas.
A Few Tips For Cleaning An Oil Painting At Home
Always Do A Patch Test
Before jumping right into the cleaning oil painting, make sure to do a patch test.
Perform the cleaning technique on a small part of the painting and wait for a few minutes to see how it reacts.
If there’s no reaction, then you can proceed with the technique.
Turn On The Lights!
Use ample lighting when you’re cleaning an oil painting on canvas. If possible, use the natural source of light.
Slow As A Snail!
To clean oil paintings surface, you have to be deliberate with your approach.
The surface of oil painting is delicate and using too much pressure while dry brushing can cause the paint to flake off.
Save It From The Sun
Keep the painting away from direct sunlight as sun rays can degrade the surface of the painting.
UV rays can cause discoloration, flaking, and speed up the aging of the oil painting.
If it requires you to hang the painting where there’s sunlight, you can frame the painting with UV-resistant glass.
One of the best ways to preserve the painting after it’s cleaned is to frame it.
Framing the painting will safeguard it against dust, indoor pollutants, and other external factors.
Keep Away From Smoke
Smoking near the painting can permanently damage the oil painting.
Any form of smoke, whether it is from cigarettes or is coming from the kitchen, can stain the painting and change its properties.
Ask The Experts
We can’t stress this enough.
A professional art conservator or restorer would be better able to clean and restore your oil painting.
Bonus Tip: Oil Painting Is The Way To Go
Among all the mediums, oil painting is the most versatile medium ever. No wonder why it is preferred by most artists around the world.
