Removing the plastic taste of water cups is a common need, and I will detail some effective methods below.
First of all, brine deodorization is a simple and effective method. First, wash the cup with detergent to make sure the surface of the cup is clean. Next, add the right amount of salt to the water to make a diluted brine (about 30% concentration). Pour the brine into the cup and shake the cup evenly so that the brine fully touches the inner wall of the cup. After letting it sit for two hours, pour off the salt water and wash the cup thoroughly. This method can help remove the plastic smell.
Another method is milk deflavoring. Wash the cup with detergent first to make sure it is clean. Then pour in two tablespoons of fresh milk, cover the cup and shake for about a minute to allow the milk to fully touch the inner wall of the cup. After that, pour out the milk and wash the water bottle thoroughly. The proteins in milk can adsorb and neutralize plastic flavors, helping to remove off-flavors from cups.
In addition, orange peel or lemon slices can also be used to remove the plastic taste of the drinking glass. Wash the cup thoroughly with detergent first, then add fresh orange zest or lemon slices, cover and let it sit for about four hours. The natural aroma in orange peel or lemon slices can help neutralize the plastic taste. After that, wash the water bottle thoroughly to make sure there is no residue.
It should be noted that the above method is suitable for most plastic cups. If your water bottle has a special coating or other special treatment, please consult the manufacturer's guidelines or consult a professional before using these methods.
In addition, daily maintenance is also very important. Keeping your water cup dry and clean is key to preventing plastic smell. After each use, wash the water bottle promptly and make sure it is completely dry.
To sum up, the methods to remove the plastic taste of the water cup include the brine deodorization method, the milk deodorization method, and the orange peel lemon slice deodorization method. Choose the right method and operate according to your personal preferences and actual situation.
