Over time, your walls may have started to look less than new. When you first painted your home, you might have admired its beauty. But beauty fades.

How to clean walls without stripping paint

What’s the best way to clean painted walls? It’s the question that has baffled humankind for decades. Luckily, there’s a way to make your walls mark-free without running your paint job. You have to know how to get it right ahead of time. Before you dust off your cleaning products and get to work, you must ensure that you’ll get it 100% right.

Don’t panic. We’ve got the cleaning tips you need to ensure that your walls look as good as new once again. In three simple steps, free your walls from grub and grime. Ready to get started? Follow our simple guide to make sure that your home looks spotless again.

What you will need:

  • Lightweight sponge
  • Washing up liquid
  • Microfibre floor mop (or microfibre cloth)
  • Dry cloth
  • Two bowls
  • Warm water
  • Cool water

Step 1: Get rid of the excess dust

Washing a wall without dusting first is a real mistake. When you add water to dust, you cement it onto the paintwork. That is a terrible idea if you want your walls to look as good as new once again. So, rather than going at it with a damp cloth, you must do this first.

Get started by getting rid of any excess dust on the wall. That is often easier said than done. You can’t use any old cloth to do the job. Instead, grab a microfibre cloth or a microfibre floor mop to get to work. Ensure that the material is entirely dry.

When you have done that, gently wipe the cloth over the walls. You want to be as thorough as you can here. The truth is that there may be some grime there that you cannot see. If it has been a while since you painted the walls, you may not notice the dull look that has begun to appear. Dust and dirt can make your walls look less than attractive.

It goes without saying that you should take down any pictures or mirrors ahead of getting started. Use a sweeping motion across the wall as you work. You don’t want to apply too much pressure here. However, you should cover as much of the surface areas as possible. When you look at the microfibre fabric, you should notice that it has started picking up some dirt there.

Step 2: Wash any scuff marks off

Are you dealing with scuff marks? You might find fingerprints around your walls or even areas where the paint has marks on it. Getting rid of these flaws can be challenging. But will washing the walls ruin the paint? The short answer is no. However, you have to know what you’re doing here. If you go in too hard or too wet, you risk messing it up.

To start, grab a bowl and fill it with warm water and wash up liquid. You don’t want this mixture to be too soapy, so you should avoid using too much of the cleaning product. Instead, use around half a teaspoon to a couple of pints of water. Next, you can check whether the water is too bubbly. If that is the case, add more water to dilute it.

When we talk about how to clean painted walls, it’s important to remember to go in easy. First, you should get yourself a lightweight sponge to use. You want to avoid using a sponge that has any rough areas on it. These could mark or even scuff the paintwork when you are cleaning. Instead, you need to choose a soft sponge all the way around.

You will need a separate bowl with cold water on the side. When you are cleaning the walls, you will use this to rinse off any excess. Pop it next to you on the floor.

Once you’ve set up all of the above, dip the sponge into the warm water and washing-up liquid mixture. Squeeze it well. You need to make sure that there is as little excess as possible. If the sponge is too wet — and the paint is not waterproof — you may find that it starts to damage the paint as you clean. So, give it a thorough squeeze before you start.

Begin at the bottom of the wall and work your way up. While that approach may seem counterproductive, it could be the easiest way forward. As you move the sponge, you will catch any liquid, which means you won’t get any nasty streak marks. You should ensure that you use a ‘dabbing’ motion. Don’t rub the paint or move the sponge across it.

There’s an element of trial and error here. You don’t want to get the walls too wet, or you could hinder the paint. For that reason, you should start with a small section, dab it, and then take a look. You might want to wait a minute for it to dry to check there is no damage.

Step 3: Rinse and blot the area

The last thing you want is to use too much soap on painted walls. That is a real mistake. With that in mind, when you have first gone over the area, the next step is to rinse the sponge. You can use the cold water in the bowl to do this. Dip the sponge and squeeze it to get rid of any excess water. Nothing could be easier.

Use the soap-free sponge to go over the area that you have cleaned. Once again, you don’t want to use too much water on these areas. The sponge should be damp rather than wet. You can use the dabbing motion once again to get this right.

Finally, grab the dry cloth and get to work. The last part of the cleaning process is to blot the area. You need a clean, dry cloth to do this. You might find that a cotton cloth, or even a microfibre one, does the job best. Next, you should dab the areas that you have cleaned. Ensure that these areas are completely dry. You don’t want any water marks on them after all.
