*Try posting a bit more so your post isn't boring*Napisan for us as well!
Oh and a drop or two of eucalyptus in the flusher to give it a nice smell!
Hi mate, I use the napisan cap for measure and add about 1 litre of water.When u say a cap full do u mean napisan bottle cap or measuring cap that comes with toilet, and also how much water do u mix with the napisan or chemical to start with?
