Comet is often used to clean and deodorize hard and nonporous surfaces without scratching them. Its liquid, powder, and cream variations are ideal cleansers for removing stains from natural marble, fiberglass, ceramic, tiles, and other hard surfaces. 

It’s been stated on Comet’s official website that all of the brand’s products are not recommended to be used on carpets or other soft surfaces. This is because its abrasive nature can damage the carpet’s fibers, leaving behind a residue that’s painstaking to remove. 

With that in mind, we don’t recommend using Comet on carpets, as there are better alternatives to get the job done. In this article, we will cover the reasons why, alongside some alternatives to use instead when cleaning your carpets.

Why You Should Not Use Comet to Clean Carpets

There are various reasons why you shouldn’t use any of the Comet product ranges on your carpets or rugs. Let’s take a closer look at these reasons:

  • It Can Damage Carpet Fibers: While it may be effective for cleaning other surfaces, Comet can cause significant damage to carpets. This is due to the abrasive particles in the product that can wear down the delicate fibers over time, leading to fraying, thinning, and even holes in your carpet.
  • It Leaves a Heavy Residue: Unlike specialized carpet cleaners that are designed to be easily rinsed out, Comet tends to cling stubbornly to carpet fibers. This residue not only makes your carpets feel crunchy and stiff but also attracts dirt and grime more easily, making them appear dirtier faster.
  • It Can Potentially Discolor Carpets: Harsh chemicals found in certain Comet cleaners can potentially strip away the color from carpets, leaving unsightly patches or fading areas behind. This can significantly affect the overall appearance of your carpet and make it look worn out and aged before its time.
  • It Poses Health Risks: The powdery residue left behind by this cleaner can easily become airborne and be inhaled by children or babies playing on the floor. This can lead to respiratory irritation or reactions, especially for individuals with sensitive lungs or allergies.
  • It’s Not Formulated for Carpets: Overall, Comet is just not designed to be used on carpets. The manufacturer clearly states that it should not be used on soft surfaces so opt for cleaners that are specifically formulated for carpet-cleaning instead. 

What Is Comet Made Of?

Comet products commonly consist of four main ingredients, one of them being calcium carbonate which acts as a mild abrasive agent. Sodium carbonate serves as a cleaning and water-softening agent that also helps break down grease and stains. 

Another ingredient, known as sodium linear alkylbenzene sulfonate aids in removing oily and greasy residues, lifting them from the surface with ease. Lastly, fragrances help leave a pleasant scent while other surfactants and sometimes dyes are also included in the ingredients list.

Alternative Carpet-Cleaning Solutions

Here are some safe alternatives that you can use when cleaning your carpet instead of using Comet. These options are proven to effectively remove stains and dirt without causing any damage. 

Dedicated Carpet-Cleaning Solution

One of the easiest ways to remove grime from carpets is to use a dedicated carpet cleaner. These products are specifically formulated to tackle tough stains and leave your carpets looking fresh and clean.

We had great results using the OxiClean Carpet Cleaner. This product contains hydrogen peroxide, surfactants, and active ingredients that work to break down and lift stubborn stains. Furthermore, it’s safe to be used on all carpet types, including nylon and synthetic fibers.

To use a carpet cleaner, start by vacuuming any loose dirt or debris from the carpet. Then, apply the cleaner directly to the stained area, letting it sit for a few minutes to allow it to penetrate the stain. After that, gently blot the area with a clean cloth or sponge to lift the stain out before blotting the area again with a clean damp cloth to remove any excess residue. 

Vinegar & Baking Soda

If you’re looking for something more natural and easily available, then try using vinegar and baking soda. Vinegar is known for its stain-lifting properties while baking soda excels at eliminating unpleasant odors.

All you need to do is combine equal parts of vinegar and water in a spray bottle and apply this to the stained portion of your carpet. Then, allow it to sit for a few minutes before sprinkling baking soda over the treated area.

Now, gently scrub the stain away with a soft brush or cloth. Finally, use a vacuum to suck up the residue and enjoy cleaner, fresher carpets without any harsh chemicals.

Frequently Asked Questions

Here are some frequently asked questions about using Comet cleaners on carpets. If you would like us to add and answer your question, please get in touch with us. 

Will Comet Stain My Carpet?

Yes, there is a possibility that Comet can stain your carpet. This is because certain Comet products contain dyes and chemicals that have the potential to discolor your carpet. These stains can be quite difficult to remove, especially if they are not addressed promptly. Therefore, to avoid this issue, it’s recommended to use a protective barrier, like a mat, in areas you tend to clean with Comet to prevent contact. 

How Do I Get Rid of Comet from My Carpet?

If you’ve previously used a Comet cleaning product on your carpet by accident, we recommend two methods to completely remove any residue that may still be lingering between the fibers. First, use a vacuum cleaner on its highest setting to try to dislodge particles and any remaining dried product from your carpet.

The other method is to use a damp cloth and gently dab it onto the areas where you’ve applied the Comet products. The good thing about Comet is that it’s water soluble, but because carpets don’t fit into your standard washing machine, you will need to blot the product away instead.

Keep repeating the dabbing and blotting process until all of the residue is dissolved. Then, leave it to air dry or use a stand fan on the highest setting to speed up the drying process. 

What Other Surfaces Should I Not Use Comet on?

In general, avoid using Comet on soft surfaces such as fabrics and clothing. It is also not suitable for wood, glass (except with Comet Classic Window), plastic, and acrylic. 

However, you can safely use Comet on Corian, Formica, porcelain, fiberglass, and stainless steel. If you plan to use Comet on any other surface, it’s advisable to test in an inconspicuous spot beforehand to ensure compatibility.
