To clean mould off a ceiling effectively, there are several methods, with two common and effective ones being the use of diluted bleach solution or white distilled vinegar.

Using Bleach Solution

• Mix one part bleach to ten parts water.
• Wear protective gear such as gloves, goggles, and a mask.
• Dip a cloth in the solution, squeeze out excess liquid, and wipe the mouldy areas.
• Use a small brush (like a toothbrush) for corners or difficult spots.
• Apply the solution again the next day to prevent mould regrowth.
• Make sure the room is well ventilated during and after cleaning to avoid inhaling fumes.

Using White Distilled Vinegar

• Use undiluted white distilled vinegar or mix with water in a spray bottle.
• Spray or apply the vinegar directly on the mould and leave it for about an hour.
• Wipe the area with a cloth and plain water afterward.
• For stubborn mould, scrub gently with a brush after applying vinegar.
• Absorb excess moisture with a dry cloth and allow the room to dry completely.

Additional Tips

• Identify and fix the cause of mould (excess humidity, poor ventilation, leaks).
• Use protective equipment while cleaning.
• Regularly apply vinegar to mould-prone areas to prevent recurrence.
• Use specialist mould sprays for severe or persistent mould.
• Improve ventilation using extractor fans or dehumidifiers to prevent mould regrowth.

These methods will remove mould safely and efficiently while helping to prevent it from returning.
