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.

RMR-141 Disinfectant and Cleaner is our top pick because it works on nearly any surface. It's easy to remove mold and mildew growth with this powerful formula, that's a fungicide (kills mold or mildew at the roots), mildewstat (helps prevent re-growth of spores), and virucide (kills viruses).

【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.
