Cleaning the shower is an obnoxious but necessary chore if you want the tiles and glass to sparkle. One of the most dreaded aspects of cleaning a shower is removing limescale from the door. What is this buildup, and how can you remove it? Glass Doctor® has the information you need!

What is Limescale?

Also known as calcium carbonate, limescale is a hard, crusty deposit that ranges in color from white to green. It’s especially prominent in homes with hard water. When this mineral-rich water streams from the showerhead, it clings to the glass, tiles, and fixtures. Then, when the water evaporates, the deposits remain behind. Limescale occurs in other places besides the shower, including tea kettles, dishwashers, plumbing fixtures, and pipes.

How to Remove Limescale

The trick to removing limescale is to cut through the mineral buildup with minimal abrasion. Here’s how:

  1. Bring one cup of white vinegar to a boil on the stove or in the microwave. Carry the pot or bowl of vinegar into the bathroom, set it on a potholder, and allow it to cool slightly.
  2. Protect your hands with rubber gloves.
  3. Dip paper towels into the hot vinegar and stick them to the glass. The slightly acidic nature of vinegar allows it to soak into and loosen the mineral deposits.
  4. Let the vinegar sit for 30 to 60 minutes. Spray the paper towels occasionally with vinegar from a spray bottle to make sure the glass stays wet during this time.
  5. Sprinkle a damp rag or sponge with a generous amount of baking soda. This mild abrasive reacts with vinegar to generate extra-effective cleaning power.
  6. Wipe down the shower door gently but avoid vigorous scrubbing, which could scratch the shower door.
  7. Pour distilled water over the glass to rinse off the vinegar and baking soda. If limescale remains, repeat the baking soda scrub until all buildup has been removed.

How to Prevent Limescale on Shower Doors

While the vinegar soak and baking soda scrub should restore your shower doors to like-new condition, be aware that tough limescale buildup may require a commercial calcium carbonate remover. These tend to be toxic, so read the directions carefully and ventilate the bathroom while using them.

Cleaning the shower is a chore you want to put off for as long as possible. You might consider using Clear Choice Surface Protector from Glass Doctor on your new shower door to make it easier to maintain. Follow these suggestions to slow limescale buildup, so you don’t have to clean the shower door as often:

  • Hard water treatment: The most effective option is to install a water softener to treat hard water at the source. This way, the water that sprays from the showerhead contains fewer minerals, and limescale buildup occurs more slowly.
  • Preventative vinegar spray: If you don’t have the budget to install a water softener, you can still prevent limescale with vinegar. Keep a spray bottle of vinegar in the shower and squirt the door after each use. Then, dry the glass with a towel or run a squeegee over the door.
