Use vinegar
Vinegar is an effective way to remove lime and calcium deposits from plastic containers. It is a natural acid that can break down mineral deposits without damaging the plastic or leaving a residue.
To use vinegar to remove lime and calcium deposits, start by mixing equal parts vinegar and water in a sink or container large enough to submerge the plastic item. If the plastic item is too large to submerge, you can also moisten a washcloth with vinegar and rub it over the deposits. Let the plastic item soak in the vinegar and water solution for at least 10 minutes, or up to 30 minutes for heavier buildup.
After soaking, use a soft cloth or sponge to wipe away the deposits, using circular buffing motions. For stubborn stains, dip a toothbrush in vinegar and scrub the affected areas. Rinse the plastic item with hot water to remove any remaining vinegar solution.
For extremely tough stains, you can soak the plastic item overnight in a 50/50 mixture of vinegar and water. In the morning, scrub the item with a cloth and allow it to air dry.
In addition to removing lime and calcium deposits, vinegar can also be used to freshen up the inside of machines, such as washing machines, dishwashers, and kettles. Simply use a cup of vinegar in place of detergent or pour it into the base of the machine and run a normal cycle. For kettles, quarter-fill with vinegar, let sit for an hour, then boil and rinse with cold water several times.

Try lemon juice
Lemon juice is an effective and natural way to remove lime and calcium deposits from plastic containers. Lemon juice is acidic, which helps cut through challenging limescale buildup while also disinfecting the surface.
To use lemon juice to remove lime and calcium deposits, start by squeezing a couple of lemons into a bowl to collect the juice. Avoid using a lemon squeezer, as you want to keep the lemon flesh intact. Then, take a lemon half and secure it to the spout of your tap, twisting gently until it stays in place. The lemon fibres and chambers should catch on the edge of the spout, keeping the lemon in place. Leave it for about an hour, then rinse and scrub the tap clean.
For plastic containers, create a lemon juice and sunlight combination to remove discolouration and kill bacteria. Rub the container with lemon juice and leave it in direct sunlight for at least one to two days. You can also soak the containers in lemon juice for a few hours and then rinse them with cold water to remove any traces of lemon juice.
Lemon juice is a mild acid that can effectively dissolve calcium carbonate. It is a natural alternative to harsh chemicals and can leave a pleasant smell behind. However, it may require more effort and time compared to other methods.

Apply a paste
To remove lime and calcium deposits from plastic containers, applying a paste is a great method. This is a gentle approach that is effective in removing hard water stains and mineral deposits.
Baking Soda Paste
Create a paste by mixing baking soda and water in a small container. Stir the mixture until it forms a thick paste. Apply this paste to the affected areas of the plastic container. Allow the paste to sit for 15 minutes to 30 minutes. Then, rinse the container with warm water. For severe mineral deposits, use an old toothbrush to gently scrub the stains before rinsing.
Vinegar and Baking Soda Paste
Alternatively, you can make a paste by mixing vinegar and baking soda. Combine equal parts of vinegar and baking soda in a small dish and stir until it forms a paste. Apply this paste to the discoloured container, ensuring it covers all the affected areas. Leave the paste on for about 20 minutes, then rinse the container with warm water. Finally, dry the container thoroughly.
Lemon and Baking Soda Paste
Another option is to combine lemon juice with baking soda to form a paste. Squeeze the juice of one or two lemons into a bowl, depending on the quantity of paste needed. Add baking soda to the lemon juice and stir until it forms a thick paste. Apply this paste to the plastic container, ensuring it covers all the stained areas. Let the paste sit for 15 to 30 minutes. Then, rinse the container with warm water and dry it completely.
These paste methods are effective in removing lime and calcium deposits from plastic containers. They are gentle on the plastic material while being strong enough to dissolve the mineral buildup. Always test these methods on a small area of the container first and follow the manufacturer's instructions for cleaning and care.

Soak in a solution
Soaking is an effective way to remove lime and calcium deposits from plastic containers. There are several household liquids that can be used for this purpose.
One option is to use vinegar. For this method, mix two teaspoons of white vinegar for every cup of water in a large basin. Place the stained containers in the basin, ensuring they are fully submerged. Leave the containers to soak for at least one to two hours. Then, dry the containers with a cloth and air-dry them overnight to eliminate any lingering vinegar smell. Alternatively, you can fill your sink with enough hot water to submerge the plastic container. Pour half a cup of vinegar into the sink for every gallon of hot water. Let the container soak for 30 minutes, then wipe it with a dishcloth and rinse with hot water.
Lemon juice is another effective soaking solution. Cut a lemon in half and gently squeeze the juice into a bowl. Take a lemon half and attach it to the spout of your tap, twisting gently until it stays in place. Leave it for an hour, then rinse and scrub the tap clean. If any scale remains, replace the lemon and scrub again. For plastic containers, you can rub lemon juice onto the affected areas and leave it in the sun for at least one to two days. The lemon and the sun's ultraviolet rays will work together to remove discolouration and kill bacteria.
Commercial limescale removers can also be used for soaking. Mix equal parts of a remover, such as CLR Calcium, Lime, and Rust Remover, with warm water. Apply the solution directly to the stain with a brush, cloth, or sponge and let it soak for two minutes. Then, rinse the container promptly with cold water.
Another option is to use denture tablets. Fill a plastic container with water and place a denture tablet inside. Let the tablet fizz for 30 minutes, then rinse the container with warm water.
