How to clean a ceiling before painting

Before you begin painting the ceiling, preparing the room will ensure the job goes more smoothly. Remove all furniture from the room, if possible, to avoid any spatter or paint damage. Prep the ceiling by removing any dust or grime. Paint will adhere poorly to a dusty ceiling.

Flat ceilings: Combine 1 cup warm water, 4 drops liquid dish detergent and 2 tablespoons white vinegar in a spray bottle. Lightly spray the area then go over it with a damp paint roller or microfiber mop. Cover the roller with a clean white cloth dipped in water and dab the area again to remove soapy residue.

You can paint over a dirty, glossy, chipping, and flaking surface, but don’t expect your handiwork to hold up over time. For new paint to stick, your interior or exterior surface needs to be clean and free of dust that could interfere with your paint’s ability to adhere to walls, trim, and ceilings.

Dust and clean the walls. For most surfaces, use a towel or a vacuum cleaner. When painting a bathroom or kitchen, wash the walls with a solution of approximately three teaspoons of laundry detergent to one gallon of water. Scrape any cracked or flaking paint with a paint scraper.

If you’re painting an entire room, first paint the ceiling, then the walls. It’s also usually better to paint large areas like walls before repainting the trim; because you’ll work more quickly when covering open areas, this can result in roller spatters, overspray and occasional errant brushstrokes.

General Paint Preparation

Combine equal parts vinegar and water in a bucket. Wipe down the entire wall with the solution to remove the invisible grime so you have a clean surface for priming and painting. Dust also collects on top baseboards and trim. Wipe these areas with the vinegar solution before you paint.

Washing your walls and trim is a good idea to remove any grime, cobwebs, dust or stains that may prevent your paint from adhering. Just use a mixture of lukewarm water and mild soap to wash your walls, gently rubbing in a circular motion. And be sure to rinse using a slightly damp cellulose sponge.

Mix water and dish soap

Now that the dust is wiped away, it’s time to wash walls. Fill one bucket with a gallon of warm water and mix clear liquid hand or dish soap and water in the other. Soak a cloth in the solution, and wring it out well.

Mix three or four drops of dish detergent in half-filled bucket of water. (Or you can go “old school” and do the cleaning with vinegar: Use two or three tablespoons of distilled white vinegar to a gallon of water. Using vinegar to clean a painted room can be surprisingly effective.)

White vinegar is a mildly acidic product that cleans, deodorizes, and disinfects. It can also kill 82% of mold species, including black mold, on porous and non-porous surfaces. You can use it safely on most surfaces, and its offensive odor goes away quickly. Pour undiluted white vinegar into a spray bottle.

Vinegar will not be harmful to the paint on the walls, so do not worry when applying how to clean the stain on the wall with vinegar. Fill a bucket with clean water and add the vinegar, making sure to replace the water when it becomes dirty.

Clean away.

This is especially helpful if your walls have grease stains on them. And if that isn’t getting the job done, create a solution of 1 cup ammonia, ½ cup vinegar, ¼ cup baking soda, and one gallon of warm water. Put the solution into a spray bottle, and spray onto the wall (a light layer – no need to soak it).

Vinegar is a great all-purpose cleaner and can also be used to effectively clean walls. You can create a simple cleaning solution with vinegar and water. Even though it’s a natural solution, be sure to perform a spot-test before proceeding.
