A mirror is often at the heart of a bathroom, but before you know it can become covered in smudges that just can't pass unnoticed whenever you look into it. But whether it's splashes of toothpaste, finger marks or a build-up of dust, it can take a mammoth effort to get it crystal clear and sparkling again.

Hours can be spent with glass cleaners, polish and a microfibre cloth only to keep finding new pieces of dust or some cleaner that hasn't quite been wiped away. But one household item has a hidden secret mirror cleaning power, and if you don't have it lying in the back of a bathroom cupboard it will only set you back £1. The solution - your classic can of shaving foam.

She added: “The reason why shaving cream is effective for cleaning mirrors is that it contains surfactants, which help to break down dirt, oil, and grime.

“Simply apply a thin layer of shaving cream on the mirror and wipe it off with a clean, dry cloth to remove any streaks and smudges.”

Not only can it remove a whole host of marks but it leaves mirrors, fixtures and fittings looking like they've been polished.

Another bizarre benefit of using the foam to wipe down a mirror has left many cleaners baffled as the cream can prevent the mirror from fogging after a steamy bath or shower.

The foam creates a barrier that helps to repel water droplets, stopping condensation and keeping your mirror crystal clear.

Its water-repelling ability isn't just magic, the foam contains certain hydrophobic ingredients that are designed to keep water away while shaving, but just so happen to create the same effect on your glass and mirrors.

While branded shave foams can cost up to £4, savvy shoppers can find much cheaper own-brand options such as one from Boots that costs a much more budget-friendly £1.
