Really simple to use and very effective. It appears to be working on some of the places but others would seem to need more applications. We used the product to remove mould from our shower cubicle sealant and it worked fairly well but on the sealant around a door not so well. I am going to give it another try later.

【Easy to Use】 After drying the surface, apply the mould removal gel to the mould and mildew surface, cover it completely, wait for 6-8 hours, wipe it off with a towel or rinse with water.

Borax. This is one of the best products to use for mould removal around the house. Borax is a natural compound and although it's toxic when swallowed, it is fairly safe to clean with this product.
