How to Clean Walls?
Knowing how to clean walls is the foundation of any successful painting project. Cleaning walls is not necessarily the most interesting thing to do, but there is precision and technique that come with cleaning in preparation for painting.
Remove furniture, wall hangings, etc, and open full access to all. Light cleaning can be just a few drops of dish soap dissolved in warm water in a bucket. A soft sponge or even a microfiber cloth may just be used. Rub gently while working in small sections, taking care to prevent streaks: from top to bottom.
Tough stain or greasy walls that are especially prone to kitchen and bathroom areas require a game-changer: the TSP wall cleaner. Such cleaners cut away dirt and grime with ease so walls are almost spotless and need only rinsed off with fresh water.
TSP Wall Cleaner
TSP wall cleaner, or trisodium phosphate, is the gold standard for a game-changer in wall preparation. It's the gold standard for spotless surfaces before painting, as it's a powerful cleaner that can attack grease, grime, and even stubborn stains. This is a favorite of both professionals and do-it-yourselfers.
TSP is indispensable when dealing with particularly dirty walls, whether in kitchens, garages, or high-traffic areas. Its grease-cutting ability makes it ideal for tackling residues that ordinary soap and water cannot remove. It also preps glossy or semi-glossy painted walls by slightly roughening the surface for better paint adhesion.
To use TSP, dissolve the recommended amount in warm water. Gloves are a must, as the solution can be quite harsh on the skin. Apply the mixture using a sponge or a soft cloth, scrubbing gently but thoroughly. After cleaning, rinse the walls with clean water to eliminate any lingering residue, as leftover TSP can interfere with paint application.
Sanding Walls Before Painting
While cleaning is important, sanding walls before painting is also a critical step that ensures a flawless finish. Sanding smooths out imperfections and also helps paint adhere better by slightly roughening glossy surfaces.
Start with your walls. If the walls have old paint, rough spots, or textured finishes, they must be sanded. General smoothing should be done using fine-grit sandpaper around 120- to 150-grit. In heavily textured or glossy walls, use medium grit to peel off the top layer of paint quickly.
Sanding is particularly crucial in areas that have been patched or after applying a TSP wall cleaner, as it ensures that the spots blend perfectly with the rest of the surface. For high areas or ceilings, consider a pole sander to make the process easier and more ergonomic.
How to Clean Garage Walls Before Painting?
Garage walls often face layers of grime, grease, and dust. Thus, preparing them for painting is a unique challenge. Understanding how to clean garage walls before painting is the key to getting a durable, smooth finish.

Dry brushing or vacuum to remove cobwebs, dust, and loose debris in the walls. For deeper cleaning, mix water, detergent, and vinegar. This combination is effective in dealing with common stains and dirt not damaging the wall.
For garages with oil stains, degreasers or a TSP wall cleaner are essential. Apply the cleaner to the stained areas with a sponge or scrub brush and rinse the walls thoroughly to remove any grease and oil residue. Rinse off any cleaner residue on the walls with clean water.
How to Prep Walls for Painting?
The preparation is the foundation for a successful painting project. Preparation on how to prep walls for painting goes beyond just cleaning's more about preparing an ideal surface so that the paint sticks beautifully and stays longer.
First, inspect the walls for cracks, holes, or uneven surfaces. Then, apply quality spackling compound to the imperfections, and when dry, sand with fine-grit sandpaper. For glossy walls, it's especially important to sand so the surface becomes less shiny and better able to take paint.
After repairs, wash the walls completely. Use a TSP wall cleaner or a mild detergent solution if the walls are highly soiled. Be careful – paint won't stick well to greasy or dusty walls. Rinse with clean water and let dry thoroughly.
Invest your time in detailed wall preparation to set the stage for a flawless, long-lasting paint job that speaks volumes about your attention to detail.
How to Clean Painted Walls?

Should I Wash Walls Before Painting?
If you ever wonder, "Should I wash walls before painting?" the clear answer is yes. Not doing so could jeopardize the longevity and look of your paint job.

Cleaning simply removes debris in order to guarantee a flawless base for a permanent finish.
The method you would use to clean depends on the condition of your walls. A mild soap-and-water solution is enough for light dust and dirt.

Because of these facts, most painters start by cleaning the walls really well. How dirty the walls are determines if they'll just use a soap-and-water solution or use a TSP wall cleaner to remove grease and grime.
In spots such as kitchens, bathrooms, and areas with heavy traffic, professionals pay extra attention to the spots where oil, grease, or mildew tends to collect. These kinds of areas require stronger cleaning agents that are applied to the walls with caution not to damage them.
How to Use TSP Before Painting?
Nothing could be more vital when preparing the walls for painting than knowing how to use TSP before painting, as this provides a clean, smooth surface on which the paint will stick perfectly. Short for trisodium phosphate, TSP is very powerful at cleaning and degreasing in the painting industry. It excels at the removal of grease, dirt, and oil, which often are difficult or hard to clean through other methods.
TSP must be mixed with warm water as stated on the package to be used. It is extremely important to wear gloves and eye protection when using TSP, as it is a chemical irritant that severely damages the eyes and skin.

In some instances, professional painters might add light sanding along with cleaning. Sanding of walls before painting smoothes out the bumps and ensures the surface is ready for painting to stick as well as possible. It's often used when the areas being painted collect dirt, such as kitchens or bathrooms.

How Long to Wait After Washing Walls Before Painting?
After you successfully clean your walls, one essential question remains, "How long to wait after washing walls before painting?" The length of time between cleaning and the time when the paint is applied all depends on your method of cleaning and the type of environment surrounding the walls but make sure they dry completely.
If you have used water and soap to clean, you can expect drying time to take about 1 to 2 hours, which depends on humidity and ventilation. However, in case you use a TSP wall cleaner or stronger cleaning agents, it is always important to ensure that the surface dries before painting so as not to retain moisture underneath. In most cases, you can wait for about 2 to 4 hours after the use of the stronger cleaning agents.

Be it removing stains, or dust, or preparing the surface for a new coat of paint, knowing how to clean walls in the house is one of the fundamental skills. Every room and finish needs a different approach to achieve the best results.
Everyday cleaning may begin by dusting the walls with a microfiber cloth or a vacuum attachment to remove loose dirt and cobwebs.

You would use a sponge or soft cloth, wring it out so that you're not pouring out too much liquid, and clean the area with a circular motion.
In areas like the kitchen, with grease and grime everywhere, a more intense cleaner such as a TSP wall cleaner might be needed. TSP is good at dissolving tough deposits, but walls should be flushed afterward to prevent any remaining deposits from drying onto them.

A solution of warm water and mild dish soap will be enough for walls with minor stains. Gently scrub the surface using a sponge or microfiber cloth and focus on the high-use areas around mirrors, sinks, and shower corners.
If there is mildew or mold appearing on the walls, mix a cleaning solution with one part of vinegar and three parts of water. Apply the solution to the affected areas and let it sit for 15 minutes.
Use a soft-bristle brush to scrub the areas thoroughly. If the mildew is particularly stubborn, add a small amount of baking soda to the mixture. Make sure to rinse the walls with clean water to remove any remaining cleaning agents.
