How to Clean Grease Off Painted Walls – How to Remove Stains from Painted Walls

Last Updated on May 7, 2022 by Bright Calister

A grease stain on any surface could be an unsightly and difficult stain to remove, thus, leading to frustration and intimidation. The kitchen, however, is a major area in the home, most likely to experience this kind of stain because meal preparation involving cooking, frying, and sauteing takes place there.

Also, those fine mists gradually collected on walls, and other surfaces are mostly experienced in the kitchen.

When this grease stays longer than it should on the wall surface, especially cooking grease, it gradually gels and bonds with the host surface, making it quite difficult to get rid of.

However, it’s no challenge beyond control. This article on how to clean grease off painted walls has been structured to help you find your way out of this mess as we’ve been about to provide you with some common household items that’d help on how to clean grease off painted walls. You want to relax and follow through with this piece for a brilliant understanding.

Remember that the more porous the grease surface is, the more difficult it to remove. But even after the stickiness is gone, you’d often get some discoloration on the surface, which usually requires repainting.

So, I’d always advise people to prime their walls with a KILZ paint to ensure that the stain doesn’t show through the new paint another time since no one can show whether or not the grease has been removed.

Below are some household items that’d help eliminate grease stains from painted walls.

Household Ammonia

Ammonia, as a gas, is a chemical compound that is intense and dangerous. On the other hand, this nitrogen-based super cleaner in its dilute household form is a must-have in the war on common household dirt and grime.

This chemical compound is versatile and can tackle a slew of chores ranging from achieving streak-free shine on glass down to making the greasiest of stains disappear. This is how it works:

Before you fully embark on this project, you want to ensure that there is proper ventilation and you’re as well safety cautious.

It is a must when working with ammonia that you always put on your chemical resistant gloves as pure chemical ammonia can result in severe burns and respiratory issues if it comes in contact with the skin.
In a container, mix two cups of household Ammonia with one gallon of water.

Get your spray bottle to apply this solution and scrub with your brush or a nylon sponge to remove the stain.

White vinegar

It’s also important to remember that vinegar should only be used on non-porous surfaces like glass, metal, or sealed countertops. The reason why vinegar is used as a grease removal solvent in the first place is that it contains acetic acid. This acetic acid tends to eat through the grease and break up the stain, saving you scrubbing time and frustrations.

Vinegar, however, is dirt cheap. Almost everyone uses it at home, so you do not need to go out and get one for this purpose. And although vinegar is safe when ingested, the acid in it can be quite irritant to sensitive areas. So you also want to avoid all contact with the eyes and prolonged contact with the skin.

Perhaps you’re allergic to scents; removing grease off your painted walls using vinegar is a very good option.

How it works:

  • Mix a part of the vinegar thoroughly with hot water while you use your spray bottle to apply the solution to the grease.
  • Allow it some time to set well, after which you wipe off with a clean rag.
  • Work in small sections and repeat the same process as often as possible until you’re sure the grease on the wall surface has been removed. Perhaps the area is large; use several rags to get rid of the grease.

Baking soda and water

Baking soda is inexpensive, non-toxic, easy to use, and remarkably effective when removing grease. Baking soda neutralizes acids and breaks down the grease, allowing you to wipe it up without a lot of elbow grease. It sure destroys grease without having to destroy your hands or the wall surface you’re working on.


  • In a container, mix about three tablespoons of the baking soda in a little quantity of warm water(a cup precisely). It gives you a paste-like texture, roughly the consistency of the pancake batter.
  • After that, you work the paste into the grease stain and rub the area gently with a nylon scrubber until you’re sure the stain has completely varnished.
  • Then, you wipe the surface clean using a clean piece of cloth.

Trisodium phosphate

Tsp is a strong cleaning agent capable of causing burns and even irritation if not managed properly. So you want to ensure safety precautions such as putting on your rubber gloves, long sleeves, and safety goggles to protect your eyes and skin.

Areas aside, the affected surface should be protected from Tsp splashes as the paint, wood, or metal can be discolored or de-glossed.

A solution of 1/4 cup Tsp per gallon of very warm water is absolutely a good place to start. However, you can increase the ratio to 1/2 cup Tsp per gallon of water for a heavy grease buildup.

Use your nylon sponge to apply the solution while wringing out the sponge to avoid dripping. Ensure working from the bottom up, as this would reduce streaking.

Then you allow the solution to penetrate deep into the wall for about two minutes to soften the grease before you proceed to scrub with a nylon scrub pad.

Lastly, rinse the affected surface thoroughly to eliminate any residue left on the wall, as this could prevent paint from adhering.

Other methods of cleaning either a painted or non-painted wall.

Cobwebs, pollution, and dust affect even the cleanest homes. Though knowing how to clean walls actually may not be on your essential cleaning list, however, if your walls are beginning to look grimy after several years, or maybe they’ve been scribbled on by enthusiastic toddlers. You may want to give them a good scrub.

And while painting a wall seem much easier to do, most walls can be cleaned if you follow these simple rules and tips below.

Dust your wall:

Before you start painting your wall surface, the first thing to always do is dust off any excess dirt. By doing this, you’d avoid the grime spread over the area you’re about to work on.

Use a lint-free cloth to get through areas you can reach while using a soft broom with a rag over its bristles or, better still, a dust mop for fixing the high areas

If there are no stains on your walls, then just dusting the surface should.

Cleaning walls with detergent

You’d often need for this is just your soap, warm water, and mop(A quality one, though).
Using water and your mildest cleaning detergent, make a cleaning solution in a bucket.
Using your soft sponge, apply the solution to the wall. Be sure not to oversoak the sponge, and if you do, wring it out properly before applying it to the surface, as drippings from the sponge can leave water stains on your walls. Leave for about 5-10 minutes. Before it gets dried, you should have your second bowl of clean water ready to rinse off the soapy solution once it’s time. As simple as it seems, this process would clean up the most painted walls.

Use baby wipes

Baby wipes practically amount to removers. They are good for removing the odd and dirty spots from your walls. However, ensure to choose biodegradable ones and be careful not to flush them down the toilet to be environmentally friendly.

Use a vacuum cleaner to clean Matt’s walls.

When your delicate matt paint is beginning to look grimy, this is where your vacuum cleaner comes in handy. While glossy paint can be easily cleaned with just a soap and water solution, the matt would require you to clean it with your vacuum cleaner. For the greatest results, use a light brush attachment.

Conclusion – How to Clean Grease off Painted Walls

While cleaning grease out of or off of anything is a pain, it is an indispensable ingredient in the kitchen. However, knowing how to effectively and safely remove it is crucial in keeping your home or working place looking its best.

If you followed all of these simple yet outstanding methods explained above, I can assure you that you’d have your wall looking as fresh as ever again.
