We have been using Harpic as our regular toilet cleaner product but we switched to Domex as we heard a lot about it. I read that it can remove all types of stains so we bought it as our washroom has some stubborn stain. But we were really disappointed after our first use only as it has no effect anywhere. Apart from this, it has made the tiles look more dirty now because it has caused two shades to appear and because of this we had to change the tiles. Also it will not spread automatically but we have to spread it by brush. Design and style of the packaging is not that good. I recommend using other products as it is not worth the money and will waste your time.
