To remove limescale in the shower cubicle, there are two ingredients you can use which are even better than vinegar

Vinegar is certainly a great "ally" when it comes to descaling and general cleaning of the shower cubicle - but there are other products you can use. Specifically, you can use one (or both) the following: hydrogen peroxide or citric acid.

1. Cleaning the shower cubicle with hydrogen peroxide

Hydrogen peroxide a great general cleaning product to use in the bathroom and, especially, the shower cubicle.

The most important advantage to using hydrogen peroxide is that it is an excellent fungicide and anti-mold agent. Due to this, you can use it on the shower cubicle's glass surfaces and the wall tiles (especially the grouting), the cubicle floor, the taps, the drain and the door panel guide rails.

Just fill a spray bottle with 3% hydrogen peroxide (10 volumes) and spray all the surfaces of the cubicle. Leave the hydrogen peroxide to act for about ten minutes and then wipe off with a cloth (or, if necessary, rinse off and dry with a dry cloth).

Be careful not to use hydrogen peroxide without wearing protective gloves and also remember to ventilate the cleaning area properly.

If you need a more abrasive product for stubborn dirt or limescale, you can mix hydrogen peroxide with sodium bicarbonate (baking soda), forming a paste which you can put on the grime (leaving to act for 10-20 minutes), and then rinsing off to finish.

Cleaning the shower cubicle with citric acid

Citric acid is also known to be a fungicide, but is decidedly more "aggressive" (ie. corrosive) than hydrogen peroxide. Citric acid is also an excellent product to use to remove limescale.

That said, citric acid is a granular product and must first be dissolved in water (ideally, distilled water). Like hydrogen peroxide, citric acid solution can be used on all the shower cubicle surfaces - just being careful to rinse it off more quickly from metal and any of the rubber gaskets.

Dissolve 100 grams of citric acid in half a liter of water and pour the mixture into a spray bottle. Spray on the surfaces to be cleaned and leave it to act for 10-15 minutes. Thereafter, rinse and dry all surfaces thoroughly. Citric acid will leave a very pleasant "citrusy/lemony" smell in the bathroom.

Be careful not to use citric acid on natural stone: if the walls and/or the bottom of the shower are made of marble or other natural stone, do not use citric acid on them. For these surfaces, it is always advisable to use specific products (or a mild soap like Marseille or Castile soap).

So, to keep your shower cubicle spotless, always keep some hydrogen peroxide or citric acid at home!
