Here is a really simple cleaning solution for a Lemon fresh toilet cleaner without the chemicals.
All you need to do is take two tablespoons of bicarbonate of soda and drop it into the toilet bowl. Then take the juice squeezed from half a lemon and add it in. Take a toilet brush and scrub the mixture all around the inside of the bowl. Do not flush straight away.
Leave for 15mins, then further scrub and flush for a zesty clean toilet!
