When soaking the kitchen towels in the liquid, I made sure to cover every inch so that there were no dry areas when it came to applying it to the ceiling.
This part was quite messy, so I would advise doing it near a sink.
As this was only a small area of mould only two towels sufficed, but I would advise those who have a large area of mould to use as many sheets of kitchen roll as necessary.
Once the kitchen towels were thoroughly soaked, it was then time to apply it to the mould-ridden areas.
As the smell is very strong, I would advise opening the windows and doors in the bathroom before spraying the liquid.
