Mum Dominica King also swears by the paracetamol trick, saying once you rub it on the hot iron it disappears like "magic".
As the woman explained, the iron needs to be on the maximum heat setting. It is then advised to hold the tablet between a pair of tweezers and carefully rub it on the hot iron plate, and the stains should begin to slide off, according to the woman.
Continue until all the marks are removed from the plate, and your iron should look new again.
"Thanks for the tip. Will try it out on my embarrassingly dirty iron before attempting to reduce large pile of washing to be done," one woman responded to the hack.
"Really! Wow! Who knew!" another excited Twitter user said.
Another handy tip is to use baking soda — make a paste from two tablespoons of baking powder and one tablespoon of water and spread over the iron's plate while cool. Rub with a non-scratch cloth, and wipe off with a damp cloth.
