I have been using Harpic for many years and I have also tried many other brands other than Harpic but I found it to be best among them.
The process to use it is very easy. There are clear instructions on the bottle which are very easy to understand. It is also not harmful for your skin like other acids and phenyls that people uses to clean their bathrooms and toilets. After using acids for long time the rashes appears on skin which you dont have to worry about with this product.
It is also very effective in cleanliness. The toilet seat and wash basins looks like new after using a little bit of Harpic.
If you want to get rid of dirty toilets and bathroom then you dont need to look anywhere else, Harpic is all you need.
