First: check the age of your home
Alberta Health Services lists textured wall and ceiling finishes among the building materials that may contain asbestos in buildings from before about 1990. If the texture is intact and you leave it alone, it isn't a health risk. The risk comes from scraping, sanding or crumbling it.
What you'll need
- A step ladder or a sturdy extension pole
- A vacuum with a soft brush attachment, or a clean, dry paint roller
- A wide lint roller, or painter's tape wrapped sticky-side out around a paint roller
- A spray bottle with warm water and a few drops of mild dish soap
- Drop cloths, safety glasses and a dust mask
Step 1: Clear and cover the room
Move what you can, and cover floors and furniture. Even careful cleaning drops a little texture. Turn off ceiling fans and let them stop completely.
Step 2: Dust it gently
Hold the vacuum brush just touching the surface and work in light, overlapping passes. Don't press or scrub. If the brush starts pulling texture away, back off.
For cobwebs and loose dust, a lint roller or tape-wrapped paint roller rolled lightly across the surface lifts debris without dragging it.
Step 3: Spot-clean stains, lightly
For small marks, mist the area very lightly with your soap-and-water mix. Don't soak it: popcorn texture absorbs water, softens and can fall off. Dab with a clean, barely damp sponge, then let it dry completely before judging the result.
Always test in a corner first. Some textures, especially unpainted ones, react badly to any moisture at all.
Step 4: Know when to stop
DIY cleaning handles light dust and the odd mark. It usually can't fix:
- Overall yellowing from years of smoking or cooking
- Grease film above a stove or range hood
- Large areas where you can't keep the moisture even, which leaves blotchy patches
- Water stains, which usually mean a leak that needs fixing first
Should you paint over it instead?
Painting a dirty popcorn ceiling is a common mistake. Smoke and grease stains often bleed through new paint, and a roller can pull the texture off. Clean it first, and many ceilings won't need paint at all. See popcorn ceiling cleaning for how we do it.
