Toilet full of rust and limescale, forget about bleach: you can solve the problem in the kitchen

The old Coca Cola remedy

The old remedy involving Coca-Cola never fails. The fizzy drink is effective against  any type of stubborn encrustation  present inside and outside the toilet bowl. It is poured into the bowl and then left to act for several hours.

Finally, the toilet is brushed and flushed. The toilet is clean and shiny, free of germs and bacteria.
