(HealthDayNews) -- If during your annual spring cleaning you find a suspicious dark spot, you can check to see if it's mold by dabbing the spot with a small amount of chlorine bleach. If the color changes or disappears, the stain is likely mold, says Health Canada.
If you do find mold:
- Throw it out if the spot is on a blanket or rug.
- If the spot is small, clean it by using one part bleach to four parts water and a small amount of a non-ammonia dishwashing detergent. Never mix chlorine bleach and ammonia.
- Identify and remove the source of water. Leaking water can also lead to serious structural damage.
