That black buildup in the corner of your ceiling is very likely mold caused by moisture (humidity, leaks, or poor ventilation). The good news: you can remove it—but you need to do it properly and safely.
⚠️ Before You Start (Important!)
- Wear gloves + mask + eye protection
- Open windows for ventilation
- Keep kids and pets away
- Never mix bleach + vinegar or ammonia (dangerous fumes)
🧪 What You’ll Need
- White vinegar or diluted bleach
- Spray bottle
- Baking soda (optional)
- Scrub brush or sponge
- Clean cloths
- Bucket of warm water
👉 Choose one main cleaner:
- Vinegar (safer, natural)
- Bleach (stronger for heavy mold)
