2015 was the worst year for mould yet. Dealing with a little baby and the mould during rainy season was a nightmare, and I was desperate for anything to help. I commented to my sister that it would be great if there were something like aquarium snails that would just hand out in the bathroom eating the mould for me, and she said "maybe there is" and immediately googled this. It sounded good, so we went out to the garden and collected some slugs.
I had bought this mini flower pot as a hide for Tiger's pet snails.
There was plenty of mould for them to feast on :/
They only really took to the grouting, but that's OK, it's the hardest part to clean anyway.
The difference between the slugged side and the not slugged side is pretty amazing. Also amazing: a "gluten free" label on BUBBLE BATH. For all the people with Celiac disease who like to drink soap, I presume.
