Water spots on plastic are typically caused by hard water, which contains high levels of minerals like calcium and magnesium. These minerals are left behind as water dries, forming an unsightly film on plastic surfaces. To remove these stains, several methods can be employed. One popular method involves using white vinegar, which dissolves the stains without damaging the plastic or leaving residue. Another option is to use denture tablets, which fizz and create an effervescent action to dislodge stains from containers. For tougher stains, a paste made of baking soda and vinegar can be applied, or commercial hard water stain removers can be used. Additionally, sanitiser, lemon or lime juice, and diluted dawn power dissolver are also effective alternatives.

What You'll Learn
Use white vinegar
White vinegar is an excellent natural cleaner that is generally safe to use on most types of plastic without causing any damage. It is also eco-friendly and non-toxic, making it perfect for cleaning food containers or children's toys.
To clean water spots off plastic using white vinegar, start by mixing equal parts vinegar and warm water. The exact amount of the solution will depend on the size of the stained item. Next, soak the stained plastic in the mixture for about 30 minutes. If the item cannot be submerged, use a cloth or sponge soaked in the vinegar solution to wipe down the item. Rinse the item thoroughly with hot water and allow it to dry.
For tougher water spots, a paste made from vinegar and baking soda can be used. Apply the paste to the stain and let it sit for 15-20 minutes before rinsing with warm water. Be careful not to scrub too hard, as baking soda is abrasive and could scratch the plastic.
For hard water spots, which are caused by water with high iron content, white vinegar can be used to cut through limescale buildup. Dip a clean cloth into a dish filled with pure white vinegar and wipe over the stains using circular buffing motions. For more stubborn stains, dip a toothbrush into the vinegar and use it to scrub away the marks. Alternatively, you can soak the plastic item overnight in a 50/50 mixture of vinegar and water.
Always exercise caution when using vinegar to clean plastic items. While it is generally safe, using too much vinegar or leaving it on for too long can damage the plastic. It is also important to thoroughly rinse the item with water after cleaning to remove any residual vinegar.

The tablets will fizz up and create a powerful bubbling action that will lift even the most stubborn of stains from the nooks and crannies of your plastic items.
For plastic containers with tough stains, fill the container with warm water and let a denture tablet sit in it overnight. In the morning, rinse the container clean. You can also try filling the container with warm water and dropping in a denture tablet for about 15 minutes before rinsing it out.

Soak overnight in vinegar and water
Soaking plastic items in a vinegar and water solution is an effective way to remove hard water spots and stains. Hard water spots are caused by water with a high iron content, leading to limescale buildup. White vinegar is a natural cleaner that can remove these stains from plastic without damaging the material or leaving residue. Its natural acidity breaks down limescale and other deposits.
To soak plastic items in vinegar and water, start by mixing equal parts white vinegar and water. You can pour this solution into a bowl or directly into a sink. If you are cleaning a smaller item, you can also use a spray bottle. Soak a microfiber cloth in the solution and wrap it around faucets or showerheads to target specific areas. For dishes or larger items, submerge them entirely in the solution. You can also place vinegar-soaked paper towels directly on the stains.
Let the vinegar and water solution sit on the plastic for at least 30 minutes and up to overnight. For tougher stains, consider adding baking soda to the mixture or applying a baking soda paste after soaking to provide extra cleaning power. After soaking, scrub the plastic with a cloth or sponge, then rinse it with water and let it dry.
While vinegar is a powerful natural cleaner, it is important to note that it can damage certain surfaces, such as granite, marble, and other soft stone materials. Always exercise caution when using vinegar on new surfaces, and consider testing a small area first.

Use baking soda
Baking soda is a great natural cleaner that can lift discoloration from plastic. It is particularly useful for removing oily residues. To clean water spots off plastic, start by cleaning the plastic with warm water and dish soap. Then, make a baking soda paste by mixing a tablespoon or two of baking soda with a little water. Apply this paste directly to the discolored areas of the plastic container. Allow the baking soda to sit for 15 to 30 minutes. Then, use a moist cloth to clean the container and rinse it with warm water. Be careful not to scrub too hard, as baking soda is abrasive and could potentially scratch your plastic items.
For stubborn stains, you can also apply a thick paste of baking soda and water to the discolored plastic and let it sit for 15 to 20 minutes before washing it away. You can also use a two-part method of baking soda and salt. After applying the baking soda paste, pour salt onto a dish rag and rub it into the plastic in small circular motions before rinsing the container out well.
Another method is to sprinkle baking soda in your plastic sink and mist it with vinegar. Let the mixture sit for at least 15 minutes and then scrub. You can also make a paste with baking soda and vinegar and let it sit overnight. Rinse the next day.
If you are cleaning a plastic pitcher stained with tea, coat the inside of the pitcher with baking soda and use a gentle dish sponge to rub it into the plastic. Rinse well.

Sanitisers can help
If you don't have sanitiser, you can use rubbing alcohol, which is highly effective at removing stains. Pour the rubbing alcohol into the container and let it sit for a few minutes. If the plastic is not a container or the outside of a container, you cannot let the object soak.
Another option is to use vinegar, which is a natural food-safe substance. Vinegar is also an excellent sanitising agent that kills many single-celled organisms and viruses. It can be used in the same way as chlorine bleach, but without the toxic chemicals. To remove water spots, use a solution of one tablespoon of vinegar per cup of water. Soak the plastic overnight using a 50/50 mixture of vinegar and water, or dip a cloth into the solution and wipe over the stains using circular buffing motions. You can also soak paper towels in vinegar, then line the sink with them, letting them sit for about half an hour.
If you want to use a stronger disinfectant, you can combine vinegar with baking soda. First, sprinkle baking soda in the sink and mist with vinegar, letting it sit for at least 15 minutes, then scrub. Alternatively, make a paste with vinegar and baking soda, then apply it to the discoloured areas of the plastic container. Allow it to sit for 20 to 30 minutes, then use a moist cloth to clean the container.
For tougher stains, denture tablets are a hidden gem. Their effervescent action and non-abrasive nature make them a super-effective cleaning tool. Simply fill your plastic containers with warm water, drop in a couple of denture tablets, and let them work their magic for about 15 minutes. Then, rinse the container and the stains should be gone.
