There was once a time when popcorn ceilings were all the rage. Hard to believe, I know. Unfortunately, back then, this “desired” look was achieved with the use of asbestos. If your house was built prior to 1990, there’s a good chance that your popcorn ceiling contains this harmful chemical. That being said, it’s best to consult a professional and leave it alone. The best thing you can do is getting it removed, but don’t try doing it yourself. If your house was built after 1990 it should be safe to clean. Proceed with caution and don’t take any unnecessary risks. Most people aren’t looking at your ceiling anyway.
If you have determined that your popcorn ceiling is safe to clean:
Cover the area with a tarp or newspapers to avoid loose debris getting all over everything.
Vacuum the ceiling with the wand and brush attachment of your vacuum cleaner. A handheld mini vac would also work for this chore.
Don’t press on the ceiling with the vacuum or more loose bits will fall. You should also wear a mask and some glasses while doing this.
