What Causes White Marks on Plastic?

Plastic is a common material used in many everyday items, but unfortunately, it is prone to develop white marks over time. Here are some of the most common causes of this problem:

Exposure to Heat or Chemicals

One possible cause of white marks on plastic is exposure to heat or harsh chemicals. For example, if you leave a plastic item near a heat source such as an oven or stove, the high temperature can cause the plastic to warp and develop white marks. Similarly, exposure to strong chemicals such as bleach or ammonia can also cause discoloration and damage.


Another possible cause of white marks on plastic is simply aging. Over time, plastic can become brittle and develop cracks that allow moisture to seep in. This moisture can then cause discoloration and other types of damage.

Improper Cleaning Methods

Using improper cleaning methods is another common cause of white marks on plastic. For example, using abrasive cleaners or scrubbers can scratch the surface of the plastic and create small grooves where dirt and bacteria can accumulate. Also, using hot water instead of cool water can exacerbate any existing problems.

Natural Wear and Tear

Natural wear and tear over time can also contribute to white marks on plastic. Even regular use can create small scratches or nicks that may not be noticeable at first but eventually lead to more significant problems. Now that you know some possible causes of white marks on plastic let’s move onto ways you might prevent them from happening in the first place!

How to Get Rid of White Marks on Plastic?

If you’ve noticed white marks on your plastic items such as containers, cups, or toys, don’t fret. There are several effective ways to remove them with items you may already have at home. Below are some methods that have been proven to work.

Baking Soda and Vinegar

Baking soda and vinegar work wonders when it comes to removing white marks on plastic.

To start, mix a paste using equal parts of baking soda and water. Apply the paste on the affected area and let it sit for about 10 minutes before wiping it off with a damp cloth.

Next, mix equal parts of vinegar and water in a spray bottle.

Spray the solution onto the plastic item and wipe it off with a clean cloth. If the affected area is hard-to-reach or small in size, you can soak the item in a bowl filled with the vinegar solution for about 10 minutes before wiping it clean.

Rubbing Alcohol

Rubbing Alcohol

Another effective method is by using rubbing alcohol. Simply apply a small amount of rubbing alcohol onto the white spot using a cotton swab or ball until it disappears. Be sure to use rubbing alcohol sparingly as too much can damage some plastics.

For larger areas, soak a cloth in rubbing alcohol and rub the white marks gently until they disappear. Make sure to rinse off any excess alcohol with warm water after cleaning.



Toothpaste is not just for cleaning teeth – it can also be used to remove those pesky white marks from plastics! Apply toothpaste generously over the affected area and rub gently using a soft-bristled toothbrush or cloth.

Rinse off thoroughly with warm water after scrubbing. Note: It’s important to use regular toothpaste instead of gel-based ones which contain chemicals that may harm certain types of plastics.

Specialized Cleaning Products

If you prefer to use specialized cleaning products, there are several options available in the market. These products are formulated specifically to remove white marks and other stains on various types of plastic materials.

Be sure to follow the manufacturer’s instructions carefully when using these products. Some may require dilution or a longer soaking time than others.

It’s also important to wear gloves and work in a well-ventilated area when handling chemical-based cleaners. Don’t throw away your plastic items just because they have unsightly white marks.

Try out the above methods using items you already have at home or specialized cleaners for even tougher stains. Remember to always test any method on a small inconspicuous area first before proceeding with the entire item, and handle all products with care.

Prevention of White Marks on Plastic


Preventing white marks on plastic is key to maintaining the appearance and longevity of your plastic items. Here are some preventive measures you can take:

Avoiding Harsh Cleaners

When it comes to cleaning plastic items, not all cleaners are created equal. Harsh chemicals can damage the surface of your plastic items and cause white marks to form over time. To prevent this from happening, avoid using any abrasive or acidic cleaners on your plastic surfaces.

Instead, opt for gentle, non-abrasive cleaners that are specifically designed for cleaning plastics. One great option is dish soap and warm water.

This simple solution is effective at removing dirt and grime from your plastic items without causing any damage. For tougher stains, you can also try using a mixture of baking soda and water to create a gentle paste that will scrub away the stain without harming the surface of the plastic.

Storing Plastic Items Properly

Another key factor in preventing white marks on plastic is proper storage. If you leave your plastic items exposed to sunlight for extended periods of time or store them in damp environments like basements or garages, they are more likely to develop white marks. To prevent this from happening, make sure you store your plastic items in a cool, dry place out of direct sunlight.

Keep them away from any sources of heat or moisture and avoid stacking them too tightly together as this can cause scratches and other damage. If you have larger items like furniture or appliances made from plastic, consider covering them with a protective textile when not in use to keep them safe from environmental factors that may cause discoloration.

Cleaning Regularly

One final tip for preventing white marks on plastic is to clean your items regularly. By keeping your plastics clean and free of debris, you reduce the chances of stains forming over time. Make it a habit to wipe down your plastics after each use with a soft cloth or sponge dipped in warm soapy water.

Dry them thoroughly before putting them away to prevent moisture buildup that can lead to discoloration. By following these simple preventative measures, you can minimize the risk of developing white marks on your plastic items and keep them looking great for years to come.

Special Considerations for Different Types of Plastic

While many plastics can be effectively cleaned using the methods outlined in the previous section, there are some types of plastic that require special care. In some cases, the white marks may be more difficult to remove or may even be impossible to remove without causing damage to the plastic itself.

Plastic Types and Cleaning Methods

When it comes to cleaning different types of plastic, it’s important to understand what you’re working with. For example, polyvinyl chloride (PVC) is a common type of plastic used in pipes and vinyl flooring. However, PVC is particularly sensitive to heat and chemicals, so it’s important not to use any harsh cleaning products when trying to remove white marks from this type of plastic.

Instead, use gentle cleaning methods such as soap and water or a specialized PVC cleaner. Polyethylene terephthalate (PET) is another type of plastic that requires special care.

This type of plastic is commonly used for food packaging and bottles but can be prone to discoloration over time. When attempting to remove white marks from PET plastics, avoid using abrasive cleaners or scrubbers as these can cause damage or scratching.

Polypropylene (PP) is a more durable type of plastic often found in food storage containers and household items like dish racks. This type of plastic can usually withstand heat and chemicals fairly well but may still require gentle cleaning methods such as soap and water or specialized cleaners designed for PP plastics.

Plastics Where Removal Is Difficult or Impossible

In some cases, white marks on certain types of plastics may be difficult or impossible to remove entirely without damaging the item itself. For example, polycarbonate (PC) is a hard-wearing type of plastic used for items like water bottles and safety glasses. However, PC plastics are prone to developing white marks over time due to exposure to heat and chemicals.

While there are methods for removing these spots, they may cause damage or discoloration to the plastic, so it’s important to weigh the pros and cons before attempting any removal. Similarly, acrylonitrile butadiene styrene (ABS) is a type of plastic commonly used in toys, electronics, and automotive parts.

This type of plastic can be difficult to clean without causing damage or discoloration, particularly if the white marks have been present for a long time. In some cases, it may be best to simply accept that the white marks are permanent rather than risk causing further damage.

Ultimately, when dealing with white marks on plastic it’s important to consider the type of plastic you’re working with and take appropriate precautions. If you’re unsure about how best to clean a particular type of plastic or concerned about causing damage during the removal process, consider consulting with a professional cleaner or contacting the manufacturer for advice.
