This mould had been around for half a year, is there a way to get rid of it?
Hi @Trever,
We had a similar question this week. Check out How to clean bathroom and kitchen mould on silicone grout? by @penpan8988. I'd recommend the same, which is to replace the silicone. If you've tried several cleaning methods and the marks have been there for six months, then it's likely not mould and rather staining from the mould that has penetrated the silicone. The only real option would be to use a bleach-based product or cut out the old silicone and replace it with a sealant. The existing silicone can easily be removed with a silicone remover, and this helpful step-by-step guide will ensure the re-application is a breeze: How to apply bathroom sealant.
Please let me know if you have any questions.
