So I tried one of those mould gel cleaners to see if it really is as magic as it sounds. I applied it to bathroom sealant and ceiling mould… was it great – watch to see the results!
The brand I bought was specifically called Mould Stain Remover by Sugemur.
It came with gloves, a nozzle for easier application and a denture brush. I applied a layer across the bathroom sealants, applied directly on a cloth to the mould on the bathroom ceiling, and I also placed some on to the tiles and grout.
After 7 hours, there was minimal results on all surfaces. There was no area it worked best, but the bathroom ceiling was the worst with no difference at all.
I would not waste your money on this particular brand.
