Have you ever seen paint with a layer of dust underneath? It can be difficult to cover even with multiple coats that can progressively darken the area. It can also be hard to see before painting. Dust particularly collects in certain areas such as corners and under ceiling vents but can be anywhere. Even lightly textured stucco walls can collect dust in the crevices of the textured wall. My walls I was working to renew were interior stucco. They had a lot of dust under the ceiling register. I recently discovered a quick way to wash my walls with tools you may already have. Here is a quick and easy way how to wash your walls with cheap basic household white vinegar and painting tools.
Why wash walls? Washing walls before painting is recommended to remove dust and grease that can affect the new paint’s adhesion or show up under it. Rooms with pets and kids can get fingerprints, pet dander, and other debris. This method can be used before painting. In addition to painting prep, this method may be used any time the walls get dusty, greasy, or dirty.
What tools can you use to make the job go faster? I got some ideas from the painting aisle. I was looking for something on a stick. What I choose was a large painting pad with a stick used for painting walls. This also makes a great wall cleaner. You also need a duster on a long stick, a spray bottle, and vinegar.
First clean cobwebs out of the corners with the duster. Then fill the spray bottle with plain white vinegar. Some people like to dilute vinegar to half strength with water, others just spray on less. Spray your walls or the painting pad with vinegar and gently go over all the walls. Spend extra time as needed on greasy areas or particularly dirty spots. Check you painting pad to see how much dust you removed and rinse as needed. Wait until the walls are thoroughly dry before painting.
Remember to spot test first. Even though I was working with stucco, I choose a new color of semi-gloss latex paint for ease of cleaning later. This is also what I would be painting over and needed cleaning first. It was what they were originally painted with. These simple painting tools worked great to clean the walls and the ceiling too. I saved a the painter pad used for cleaning the walls to use for quick dusting later.
