White harpik is good in removing the yellow stains. If it stubborn yellow stains then nearly 5 to 6 bottles require and apply and clean the toilet on daily basis. The yellow stains start to vanish. I was tired of using toilet cleaners none of them were good. Blue Harpic is good but it leaves stains on the toilet seat which is hard to remove. Apart the yellowish stains are not going. White Harpic is highly recommended. Removing Stubborn yellow stains require time but works well.
