She said: “Shower doors can easily become quite grimy over time. Luckily, you don’t need any harsh cleaning chemicals to get them gleaming again.

“Simply cut a lemon in half and dip one half in salt. Use this to scrub the doors.

“The abrasive salt content and the acidity of the lemon will eat away at all of the mineral and soap scum build-up. Plus, the lemon will also leave your shower smelling citrusy-fresh.”

Cleaners should make sure they don’t scrub too hard as the abrasive nature of the salt could scratch the glass.

Alternatively, the cleaning expert suggested you could use white vinegar if you don’t have lemon and salt at hand.

She said: “If you have water stains on your glasses, vinegar can work wonders. All you need to do is create a mixture of one part vinegar and one part water.

“Apply the mixture to the water stains and allow it to sit for around 15 minutes.

“Once the vinegar has had time to break down all the debris, you can then use a toothbrush to scrub away the scum. Then, give the glass a quick rinse and wipe the surface clean and dry.”

White vinegar can be bought from Tesco for 35p and Sainsbury’s for 40p.
