by Rigoberto Santaella - June 23, 2025

Of all the surfaces in your home that need cleaning, walls are probably far down your list—if they’re on the list at all. However, just like floors, countertops, furniture, and other horizontal surfaces, vertical surfaces also accumulate dust, fingerprints, scuffs, and scratches. That’s why knowing how to clean walls properly is essential for maintaining a clean and healthy home.

With occasional maintenance, your home’s walls—whether painted, wallpapered, or textured—can maintain their best appearance. In this article, Yorleny’s Cleaning Services shares the best way to clean walls using safe and effective methods for every room. We’ll also show you what to clean walls with, including both natural and commercial solutions, and how to tackle common issues like dirt, grease, and even how to remove mold from walls.

Discover how to wash walls made of different materials and keep them spotless year-round. Whether you’re doing routine upkeep or deep cleaning after a mess, you’ll learn how to clean walls quickly and effectively with minimal effort.

Why Cleaning Your Walls Matters (And How Often You Should Do It)

Your walls may not look dirty at first glance, but they’re a magnet for dust, stains, and odors. Knowing how to clean walls regularly is essential for maintaining a fresh, hygienic home—especially in rooms like the kitchen, bathroom, or hallway.

High-traffic areas should be cleaned at least once a month. Less active rooms like bedrooms may only need attention every few months. If you have pets, children, or smoke indoors, knowing how to wash walls more often can prevent stains and buildup from becoming permanent.

How Dirt, Grease, and Mold Build Up Over Time

Dirt, grease, and even mold can gradually accumulate on your walls due to cooking, humidity, and daily activity. Kitchens and bathrooms, in particular, are prone to these issues. That’s why it’s helpful to learn how to remove mold from walls and other contaminants before they become visible or damaging.

Signs It’s Time to Wash Your Walls

If you notice discoloration, smudges, or unpleasant odors near your walls, it’s time to act. These are signs that you need to clean up surface dirt or even hidden mold. Understanding how to clean walls in response to these signs ensures you address issues early—and helps preserve your paint, wallpaper, or finish.

What You’ll Need to Clean Walls Properly

These are the products and tools we recommend if you want to learn how to clean walls without damaging them.

Natural and Safe Cleaning Agents (Vinegar, Baking Soda, Soap)

To efficiently tackle the job of how to clean walls using natural cleaning agents, it’s important to first examine the type of wall surface and the nature of the stain. A mild soap and warm water solution is an excellent starting point for general wall cleaning.

• Most painted walls can be cleaned safely and effectively with a solution of mild dish soap and warm water.
• A 1:1 or 1:2 ratio of white vinegar to water can be used to remove oily spots, fingerprints, and sticky residues.
• A paste of baking soda and water can be used to gently scrub away stains such as crayon marks or grease.

Tools: Soft Sponges, Wall Mop, Buckets, Microfiber Cloths

When learning how to clean walls like a pro, having the right tools makes all the difference. Here are the essentials:

• Use a duster or vacuum with a brush attachment to remove loose dust, cobwebs, and debris from the walls.
• To protect furniture and floors, move them away from walls and use drop cloths or old towels.
• Soft sponges or microfiber towels are great for washing walls without damaging the surface.
• A scrub brush (with soft bristles) might be useful for removing stubborn stains.
• Keep clean cloths or towels on hand to rinse and dry.
• Two buckets are recommended: one for cleaning solutions and one for rinsing.
• Rubber gloves will protect your hands while cleaning.
• Step Stool or Ladder to access upper portions of the walls.
• Spray Bottle to apply cleaning solutions (optional).

Step-by-Step: How to Clean Walls Without Removing Paint

Cleaning the walls of your home, in general, doesn’t require much frequency, but when it does, it’s a job that requires time and dedication. We recommend planning when and how to carry out this task because there are some important factors to consider. Below are some tips to help you clean the walls of your home.

Step 1: Dust and Prep the Surface

A crucial first step in learning how to clean walls is removing dust and prepping the surface. Fine dust can make even bright paint look dingy, while cobwebs often appear unexpectedly. To dust painted walls, use a mop with a microfiber pad or disposable cloth.
Remove artwork and photos if you can. Attach a clean pad to the mop and use vertical motions, overlapping strokes, while also dusting baseboards and crown molding. Check the pad regularly to shake out or replace it to avoid redepositing dust.
You can also use the soft brush attachment on your vacuum cleaner, which is safe for wallpapered walls.

Step 2: Apply Cleaning Solution by Finish Type

Understanding how to clean walls also means choosing the right cleaning method based on your wall’s finish. Areas around light switches, door jambs, and greasy kitchen walls need more than just dry dusting. Start by removing dust and cobwebs. Then, mix a mild dish soap with warm water in one container, and have a separate container of clean water ready for rinsing.

Using a clean sponge or cloth, dip it into the soapy mixture, wring it out, and clean a manageable section of the wall from the bottom up to avoid streaks. Rinse with the clean water and allow the area to dry.

For tough stains, lightly buff the area with an eraser-type sponge after testing it in a hidden spot. Alternatively, you can use a paste made of baking soda or hydrogen peroxide to tackle crayon stains. Isopropyl alcohol and vinegar can effectively remove candle soot, but be cautious, as they may also affect the paint. Apply them gently and be sure to wipe the area clean afterward.

Step 3: Rinse and Dry the Wall Without Streaks

One of the final steps in how to clean walls is drying them properly to avoid streaks or water stains. To dry a freshly washed wall, make sure to ventilate the area well to promote quick and even drying. Use clean, soft towels to avoid scratches or residue. You can also use fans and heaters to speed up the process, but be sure to avoid direct contact with the wall.

If you encounter stubborn stains, remove them with targeted solutions, such as a mixture of warm water and mild detergent or isopropyl alcohol, depending on your wall finish.

How to Remove Mold from Walls Safely

If you’re wondering how to remove mold from walls without damaging paint or risking your health, it’s important to follow safe and effective practices. Start by protecting yourself with appropriate gear, such as gloves, a mask, and eye protection. Proper ventilation is also key when tackling mold on any surface.

Mold-Removal Techniques Using Vinegar or Peroxide

One of the best ways to clean walls with mold is by using gentle yet effective solutions. Begin by cleaning the affected surface with a mild detergent and water, or a solution of bleach diluted at a 1:10 ratio (one part bleach to ten parts water). For a safer and more natural method, try vinegar or hydrogen peroxide. These are popular answers to the question of what to clean walls with when dealing with mold. After treatment, always rinse thoroughly and let the area dry completely.

When to Avoid Harsh Chemicals on Paint

When learning how to clean walls, it’s essential to know when to avoid strong chemicals. Harsh cleaners like bleach may damage paint, especially if used on matte or older finishes. If you’re dealing with mold on painted surfaces, skip the bleach and use natural solutions like vinegar and water instead. This will help preserve the paint while still effectively addressing the mold problem.

Quick Tips to Wash Walls Fast and Efficiently

Knowing how to wash walls efficiently can save time and keep your home looking fresh. Whether you’re dealing with everyday dust or occasional smudges, a few smart practices make a big difference.

Best Techniques to Keep the Walls Clean All Year Round

• Clean stains regularly. Addressing light smudges and fingerprints as they appear is one of the best ways to clean walls and prevent long-term buildup.
• Plan for paint touch-ups. Sometimes, knowing how to clean walls isn’t enough—paint touch-ups may be needed. Keep extra paint handy for easy fixes.
• Use air purifiers and exhaust fans. These reduce airborne particles like grease and dust, helping to keep your walls cleaner for longer.
• Install wall organizers. Strategic storage can prevent wall scuffs from bags, shoes, and clutter.
• Vacuum with care. Avoid bumping into walls or baseboards to prevent accidental damage. This is especially important when you’ve just learned how to clean walls and want to maintain the results.

FAQ: Cleaning Painted Walls and Mold Removal

Can I use vinegar on all types of painted walls?

When exploring how to clean walls, many people turn to vinegar as a go-to natural solution. While vinegar can be effective, it’s not ideal for all types of painted surfaces. It generally works well on latex (water-based) and oil-based paints when properly diluted with water. However, it should be avoided on delicate finishes like matte or flat paint, which can streak or become damaged. If you’re unsure what to clean walls with, always test a small, hidden area first to ensure the paint reacts well.

What’s the safest way to remove mold without damaging paint?

The safest technique to remove mold off painted walls without damaging the paint is to use a moderate cleaning solution such as warm water and dish soap or vinegar and water. Avoid using harsh chemicals like bleach, which can damage the paint and may not be effective in the long run.

How often should walls be cleaned in a typical home?

Knowing how to clean walls also involves understanding how often to do it. In most homes, an annual deep clean is sufficient. However, high-traffic areas—like kitchens, entryways, and bathrooms—should be spot-cleaned more frequently, ideally every month. Families with pets, kids, or allergy sensitivities may need to wash their walls every 6–12 months. Establishing a regular routine ensures your home always looks its best and helps prevent buildup of grime, stains, or even mold ov
