The best way to clean a popcorn, or textured, ceiling is to use a vacuum cleaner with a brush attachment. This is a useful method for removing cobwebs, debris and dust from the ceiling.
To clean a popcorn ceiling, a person needs a ladder to place under the ceiling area that has either dust or cobwebs. After climbing the ladder, one glides the vacuum cleaner hose with the brush attachment across the dirty area. It is important to be gentle while using the vacuum to avoid damaging the ceiling texture. Similarly, water or other liquid cleaners should not be used because this also can damage a popcorn ceiling.
A popcorn ceiling, also called an acoustic ceiling, is a sprayed on texture treatment that was popular because it could hide flaws in ceilings and avoid having to plaster and sand them.
