Commercial Products for Cleaning Shower Doors

Although they contain a lot of chemicals, commercial cleaners can be extremely convenient and can help us clean much quicker.

Here are the cleaners I swear by:

  1. HG Professional Limescale Remover: There is a reason why this is called a professional limescale remover. It removes limescale in seconds. Try not to leave it on surfaces, especially metal surfaces, for too long as it can change the colour.
  2. Viakal Classic Limescale Remover Cleaning Spray: This is one of the best products to have in your arsenal for quickly tackling scum-covered glass.
  3. Cillit Bang: Similar to Viakal, this product is great at cutting through limescale. I must say it’s not as strong as it used to be, but it still gets the job done.
  4. Cif Perfect Finish: I recently introduced this to my cleaning arsenal, and it works well on stubborn spots.

My choice: In my opinion, the best glass shower door cleaner for hard water is HG Professional Limescale Remover because it works really quickly and effectively.

Natural Cleaning Solutions for Cleaning Glass Shower Doors

Using natural cleaning products is safer for you and the environment; however, I’ll be completely honest, they do not always work as quickly as store-bought products.

I am not suggesting that using commercial products is the ultimate solution. However, if your priority is to avoid air pollution and create a healthier living environment, then I’ll show you three common ingredients that work brilliantly.

Lemon Juice

As you probably already know, lemon is much more than just a fruit. It’s a powerful cleaning product that can effectively cut through mineral buildup because it naturally contains citric acid.

How to use:

  1. Squeeze the juice of two lemons into a bowl and transfer it to a spray bottle.
  2. Dilute the lemon juice with a small amount of water, approximately half the quantity of lemon juice you have. Use less water if you need a stronger solution.
  3. Spray the solution directly onto the affected areas of your shower glass doors.
  4. Let it sit for a few minutes to allow the citric acid in the lemon to penetrate and break down the stains.
  5. Use a damp non-scratch sponge and work the surface of the glass in circular motions.
  6. Rinse thoroughly with water and squeegee the excess water.
  7. If necessary, repeat steps 1-5.
  8. Polish the glass with a glass cloth.
  9. Once dry, check for any remaining hard water spots.

Tip: For stubborn stains, cut the lemon in half and apply it directly over the stains, remembering to squeeze as you go along.


Vinegar, particularly distilled white vinegar, is one of the most commonly used products for household cleaning. It’s amazing for achieving a beautifully clear glass shower door.

The acetic acid in vinegar is an incredible solvent for hard water stains. The only disadvantage is the strong smell, which might make some people uncomfortable.

How to use:

  1. Mix equal parts white distilled vinegar and water. Adjust the water content in the vinegar solution depending on the severity of the stains.
  2. Pour the mixture into a spray bottle and generously spray it on your shower door glass.
  3. Similar to using lemon juice, use a damp non-scratch sponge to work over the glass surfaces in circular motions.
  4. Rinse the door and squeegee off the excess water.
  5. As it starts to dry, you will be able to see if you need to repeat the application.
  6. Polish the glass with a glass cloth for a sparkling finish.


  • Use undiluted vinegar if you have very tough stains as this will help remove them more quickly.
  • Use distilled water if you plan on storing your vinegar solution to prevent the quick buildup of bacteria in the mixture.
  • Add a few drops of essential oil to the solution for a slightly more pleasant scent.

Citric Acid

Although derived from lemons, citric acid is a more concentrated form that many people are now using as an eco-friendly alternative to harsh chemicals.

How to use:

  1. Mix 2 tablespoons of citric acid with warm water to create a solution.
  2. Follow the same steps as with lemon juice and vinegar for cleaning glass shower doors.
  3. Apply the citric acid solution to the affected areas, scrub gently with a non-scratch sponge, and rinse thoroughly.
  4. Squeegee off the excess water and polish with a dry cloth.

Tip: If you desire a satisfying fizzing effect, you can mix citric acid with vinegar. However, be cautious and ensure proper ventilation due to the release of carbon dioxide gas during the reaction.

Best Eco-friendly Limescale Removers

If you’re looking for a gentle and environmentally-friendly solution to tackle limescale, but don’t want the hassle of making your own, these cleaners are the perfect choice.

  1. Ecover Limescale Remover: This environmentally-friendly product comes in a convenient spray bottle. It is made with plant-based ingredients and is biodegradable, ensuring it is kind to the environment while effectively removing limescale.
  2. Bower Collective Limescale Remover: Another excellent eco-friendly option, Bower Collective offers a limescale remover in refillable pouches. What’s even better is that you can post the empty pouches back to the brand for free recycling. They also provide a dispenser spray bottle for easy application.
  3. Method Daily Shower Spray: As the name suggests, this product is designed for daily use as a maintenance spray. It helps prevent the buildup of soap scum, hard water stains, and mildew, keeping your shower clean and fresh.

Essential Tools For Getting Rid of Hard Water Stains

When it comes to tackling those stubborn hard water stains, having the right tools can make a huge difference. Here are some essential tools that can help you get the job done:

squeegee for shower glass
  1. Electric Squeegee: This is a nice to have and not a must have but oh, how I love my electric Squeegee. It’s a squeegee and vacuum all in one. I personally keep one in the corner of my bathroom that I reach for after a shower.
  2. Steel Wool: If you’re dealing with tough, cloudy mineral deposits on your glass shower, steel wool can be your ally. Don’t worry about it scratching the glass doors; glass is actually tougher than steel wool. Refer to the Mohs Hardness Scale for reassurance.
  3. Magic Eraser Sponge: The melamine sponge, commonly known as the magic eraser, is effective in removing hard water stains from glass. However, be prepared to put in some elbow grease as it requires a bit more effort. Keep in mind that it may not work on hard-set stains.
  4. Razor blade: Among my collection of tools, the oven razor blade holds a special place. It’s a handy tool with disposable razors that can scrape off hard-set scum when needed. Just be careful not to scratch the glass

Maintenance Tips for Preventing Hard Water Stains

Prevention is always better than cure. Growing up with African parents, they drummed this phrase in me whilst growing up. I believe you can get to the hard water stains before they even get a chance to settle on your precious shower doors. That in my opinion is the best way to tackle it. 

Here are my best tips which I follow religiously to prevent hard water on my shower glass doors. 

1. Squeegee after every shower: Make it a ritual to squeegee your shower glass after each use, and if you feel comfortable, you may tell your guests to do the same. This is the best rule that we ever implemented in our household. Squeegee in an s pattern and don’t forget the edges and corners. I use an electric squeegee in a straight pattern because it’s a breeze to use.

2. Rain repellant: While this step is optional, I find it useful to apply a rain repellant spray occasionally after my weekly cleaning routine. Even though I’m religious about squeegeeing, the repellant adds an extra layer of protection, preventing any missed water spots from sticking to the glass.

3. Use a daily shower spray: Although I personally don’t use one, incorporating a daily shower spray into your bathing routine can be a game-changer. These sprays are specifically designed to be used after every shower, helping to prevent the build-up of soap scum and mineral deposits. It’s like a little daily insurance policy for your shower glass.

4. Don’t neglect the tracks and taps: Remember to give your taps and shower controls regular attention, as they are prime targets for hard water stains. Wipe them down regularly to keep them shiny. If your shower has glass tracks, don’t forget to clean them with a brush or toothbrush to prevent any mildew from forming. Trust me, you’ll thank yourself later.

5. Invest in a water softener: Now, I understand that not everyone can accommodate a water softener due to space and financial constraints. But if you have the means, it’s worth considering. Water softeners work wonders by neutralising the mineral content in your water supply. Remember what I said about prevention? Well, this ticks that box.

So, my fellow cleaning enthusiasts, I hope you’ve learned a thing or two or had a few “ah-ha” moments. Now, you can confidently banish any hard water stains that dare come on your glass shower doors.

Remember, consistency is key. Whether you choose to incorporate a daily squeegee routine, embrace natural ingredients, or grab a good product off the shelf, the important thing is to find what works for you. I want you to experience the joy of a clean shower door every day. It’s possible. And don’t forget to share these tips with a friend.

May your shower doors shine and hard water become nothing but a distant memory. Happy cleaning!
