A glass shower door can give your bathroom a clean and fresh look and saves you the hassle of hanging a rod and a shower curtain. However, while the glass shower door gives a cleaner look, it does tend to collect pesky hard water stains and soap scum that is almost impossible to remove. With CLR being all the buzz, people wonder if it can really be used on a glass shower door.

When it comes to soap scum and hard water stains on your glass shower door, CLR is one of the best cleaning solutions you can use. Despite the harsh chemical smell it produces, if used safely, it can clean your glass shower door better than anything else.

To learn more about cleaning your glass shower door with CLR, you must first ensure that you have read all the safety precautions and warnings. So now, let’s look at all the details you need to know to use CLR safely.

Can You Use CLR on Glass Shower Doors? 

If you have a glass shower door, you are most likely familiar with how hard it is to keep it clean regularly. You may have even tried various cleaners that failed to do what the manufacturer said they would do.

The great news is that you do not have to live with soap scum, hard water stains, or any other annoying residue that tends to linger on glass surfaces. The simple solution is to use CLR to clean your glass shower door since it is well-known that it is specifically designed for the job.

CLR, or Calcium, Limescale, and Rust Remover (on Amazon) is a product made to combat the residue that tends to build up on glass surfaces, especially those that come in contact with water—because of this, using CLR to clean the glass shower door just makes sense.

While many products on the market claim to fight and remove those harsh stains, many fall short of doing that. However, CLR has successfully eliminated these types of residue for many years.

What are the Pros and Cons of Cleaning Shower Doors with CLR?

Many of the products that CLR is known for are suited for various purposes around the house, although you can still purchase the original products. In addition, they also have more specifically designed products for bathroom surfaces that you can buy.
