To clean painted walls without leaving streaks, mix a few drops of mild detergent with warm water. Dampen a soft cloth or sponge with the solution, wring it out, and gently wipe the walls from top to bottom using circular motions. Rinse the cloth regularly and dry the walls with a clean towel to absorb excess moisture.
I've had good luck washing down walls using a pail of warm water with a small squirt of dawn dish soap (original blue) and a terry cloth rag rung out. ALWAYS start at the bottom and work up, using circular motions, so you don't get drip marks left on the wall. Use a new rag when needed.
What you're seeing is soap used in paints to aid in flow and leveling. If you wash the soap off it won't come back, may take a couple washings. This is not uncommon in bathrooms. If you still want to paint over it, clean it off somewhat, and paint right over it 2 coats.
The best solution for cleaning walls is plain warm water. To clean grease off kitchen walls, add a few drops of dish soap to cut through any accumulation. Simply dampen a sponge with your chosen cleaner and start scrubbing. The water will attract dirt, preventing it from ruining your new paint.
Take a soft sponge or cloth and gently scrub the walls in circular motions, being careful not to apply too much pressure. If the streaks persist, you can try using a magic eraser or a mixture of vinegar and water to give them a thorough but gentle scrub.
Because Magic Erasers are abrasive, you should be careful about using them on painted walls (and avoid using them on wood surfaces or stainless steel).
You can also mix equal parts vinegar and olive oil and apply to the stain with a cloth, wiping in the direction of the grain until the stain disappears. Afterward, wipe the surface down with a clean, dry cloth. Try placing an iron on a low heat setting over a cloth on top of the stain.
Professional painters often prefer a simple mixture of mild detergent and warm water, and it works wonders for most walls. A solution of warm water and mild dish soap can erase stubborn greasy spots on your kitchen walls.
Wetwall panels can be cleaned using normal soap, water and a soft cloth. Alternatively a non-scratch liquid cleaner can be used such as ShowerWall SuperClean. On a day to day basis or after every use it's best to rinse the panels and then clean off the excess water with the squeegee or a soft cloth.
A lightweight and flexible dust mop is another good option for cleaning walls and ceilings, helping you clean difficult-to-reach areas and get cobwebs out of corners and overhead shelving. Spray mops may be more suitable for cleaning a floor or the lower portion of a wall than the ceiling.
If you notice streaks on your walls after painting, try gently sanding the affected area and applying a fresh coat of paint. If that doesn't work, you may need to repaint the entire wall or use a primer before applying another coat of paint.
In my opinion, the Chomp wall mop is the greatest invention since the sponge. The teardrop-shaped swiveling mop head gets into tight corners with ease, and since the mop weighs less than 1.5 pounds, it's simple to maneuver and doesn't cause fatigue.
Brush marks are caused by strokes that leave the paint with a rough texture and visible brush strokes. The rough texture and visible brush strokes can be easily covered in a second coat of paint by using a slightly different technique than you used for your first coat.
Keep walls clean and free of dust, fingerprints, stains and smudges with Simple Green All-Purpose Cleaner. Spot clean fingerprints and other marks as soon as you notice them, and deep clean once a year to keep dirt off and maintain that freshly-painted look.
Wait at least two weeks after painting before using any water or cleaner on your walls. Typically it's best to use a soft cloth or sponge with mild, soapy water. Wipe by applying gentle pressure in a circular motion. Rinse with a clean, damp cloth afterward to remove any leftover cleaner.
Fill a bucket with warm water and add a small amount of mild dish soap. This soapy solution works well for most paint finishes like latex paint, eggshell finishes, and even semi-gloss. Avoid using harsh chemicals or abrasive cleaners, especially on delicate finishes like flat paint or oil-based painted walls.
Mix a solution of 1/2 cup white vinegar, 1/4 cup baking soda, and 1 gallon of warm water. Use a sponge to gently scrub the walls.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers and heavy-duty fans. That ensures the walls are truly dry before further repair, painting or refinishing.

Magic erasers are particularly rough on painted walls because they are chemically abrasive. Even the most durable finishes will come off if you scrub them with a magic eraser. A sponge or damp cloth is more than sufficient for cleaning painted walls.
Streaks, where paint is unevenly distributed on a wall, typically result from having too little paint on your roller or brush.
