For those who don't have sandpaper, you can practice this method.

  28 Mei 2024 21:00 - Most keys are made of metal, because they are sturdy and durable. However, after years of use, keys can rust, due to frequent exposure to water and various stains. Rust on the key risks jamming the key when used to lock the door.

If the rust stains on the key are thick enough, it will be very difficult to clean. As a result, many people choose to sand the key so that all the rust comes off. However, not everyone has a stock of sandpaper at home, right?

So, for those of you who don't have sandpaper, don't worry just yet because there is one more trick from the YouTube Smart Solution account user. This man explained that you can remove rust stains from keys by soaking them in a mixture of three kitchen ingredients.

How to clean rusty keys.

Before starting the trick, first prepare a bowl to place the rusty key you want to clean. Pour enough vinegar until the keys are completely submerged. Then, also add 1/2 tablespoon salt. Yup, those are two of the three core kitchen ingredients to practice this trick to remove rust stains from keys.

Next, add one more kitchen ingredient, namely lemon juice. Stir until all the ingredients are mixed evenly, then let it sit for a few hours so that the rust stains are no longer stubborn.

"Dip in 12 hours (Soak for 12 hours)," emphasized the owner of the YouTube Smart Solution account, quoted by BrilioFood on Tuesday (28/5).

After soaking for 12 hours, scrub the key with an old toothbrush until all the rust stains are gone. If the key is completely rust-free, rinse it immediately with running water. After that, dry the keys before using them again.

How to find out whether vinegar is still safe to use or not.

To find out whether vinegar is still safe to use, you can pay attention to the following things.

1. Expiry date.

Vinegar generally has an expiration date printed on the bottle. Although vinegar has a very long shelf life due to its high acidity, it is still important to check this date.

2. Condition of bottles and caps.

Check the vinegar bottle and cap. If there are signs of damage such as rust on the lid or leaks on the bottle, you should avoid using the vinegar.

3. Changes in color and odor.

Vinegar that is still good usually has a color and smell that is consistent with its type. If the vinegar is discolored, cloudy, or has a different odor (for example, an overly strong or strange odor), it should not be used.

4. Precipitates or particles.

Quality vinegar is usually clear (in the case of white vinegar) or has a small amount of natural sediment (in the case of varieties like apple cider vinegar). If there are a lot of strange particles or unusual sediment, it could be a sign that the vinegar is no longer good.

5. Taste.

If you are in doubt, you can try tasting a little of the vinegar. Spoiled vinegar will usually have a strange or unpleasant taste.

In general, because of its acidic nature, vinegar is very long-lasting and rarely goes "stale" like other food ingredients. However, it is always better to be careful and check the above signs to ensure the safety of using vinegar.
