How to Remove Rust Stains from Plastic Sink [6 Natural & Commercial Tips]

How to Remove Rust Stains from Plastic Sink

Rust stains on a plastic sink are a common problem, often caused by tap water. It can be due to rusted galvanized pipes, heater issues, or high iron levels. While the rust stain may seem to be horrible at first glance, there are several products that can get rid of it.

In this article, we’ve brought you both commercial cleaners and homemade ones. However, before you invest in a commercial rust stain remover, you should consider first these DIY techniques that are just as effective.

I-How to Remove Rust Stains from Plastic Sink

1-White Vinegar

If the rust stain is still new, white vinegar with water can get rid of it. Mix two parts of water with one part of white vinegar. Apply the mixture to the stain and leave it there for a few minutes. Then rinse your plastic sink and enjoy its shine once again.

2-Baking Soda

Another practical tip is to sprinkle a good amount of baking soda all over the discolored area. Spray some white vinegar over the affected spot until the mixture starts bubbling. Then, with a cloth or a sponge, rub the mixture into the rusty area.

3-Lemon Juice

Lemon juice, like white vinegar, is an excellent natural cleanser capable of removing a wide variety of stains. In addition to that, it has a pleasant odor that will make your plastic sink smell wonderful.

This time, we’re going to mix it with salt. To begin, make a thick paste by combining salt and lemon juice. Apply the mixture to the rusty stain and let it sit for 20 minutes. After that, wipe your plastic sink with a sponge or a towel and rinse it with cool water.

4-Bar Keeper’s Friend

Alright, now it’s time to start showing you the products you can get at your local grocery store. One of the cleaners we often recommend for stubborn stains, such as the one caused by rust, is Barkeepers Friend. It’s indeed an abrasive product when compared to the natural options. Yet, the results it provides are, on the whole, excellent.

Start by wetting your plastic sink. Then, sprinkle a generous amount of Barkeepers Friend over the rusty stain and rub it using circular motions. After that, rinse your plastic sink with water, ensuring nothing is left behind.

Sidenote: Do not leave Barkeepers Friend on your plastic sink for an extended amount of time. It can cause discoloration, making things worse than they already are. Instead, we recommend cleaning it immediately upon application.

5-Magic Eraser

A Magic Eraser is an excellent option for removing tough stains. It does need some elbow grease, but its results are often spectacular. Wet the sponge and start scrubbing in circular motions on the stain. Rinse the whole plastic sink and repeat if the blotch refuses to leave your sight.

6-Iron Out

Iron Out is one of the best cleaners for removing rust stains from plastic sinks. It’s easy to use and takes little time to get the desired results.

First, spray Iron Out on the rusty area and let the product work for a few minutes. After that, rinse your plastic sink well with clean water.

The main advantage of this product is that it is non-abrasive. On top of that, Iron Out is available on Amazon.

You can also use Magica Rust Remover as an alternative to Iron Out. However, please keep in mind that this product is abrasive. Even though it works well on plastic sinks, it can harm vulnerable surfaces such as Marble. So, work with caution if you decide to use Magica!.

II-How to Avoid Rust Stains on a Plastic Sink

As previously said, the most common cause of rust stains is tap water. Fortunately, there are many solutions depending on the root of the issue. For instance, if the rust stains are caused by a high quantity of iron in your water, you can solve the problem by investing in a water softener.

A water softener not only prevents rust stains but also provides better water for drinking, bathing, washing dishes, and much more. If you’d want to learn more about the benefits of water softeners, please read this article.

On the other hand, if the rusty water is a result of rusty galvanized pipes, you have no choice but to contact a plumber.

If a water softener is out of your budget range, consider installing an Iron Filter instead. This latter will eliminate iron and sulfur gas from your water supply, helping you avoid any of the above-mentioned rust issues.

As a water softener, Iron Filter also offers several benefits, including better water for drinking, preventing rust stains, and increasing the lifespan of your fixtures.

III-Conclusion

According to what we’ve found on the internet, many homeowners have suggested phosphoric acid-based products, which can be found on stainless steel cleansers. According to these people, these kinds of cleaners do provide excellent results with little effort.

Still, we haven’t tried any phosphoric acid-based products. Thus, we can’t recommend them as a safe bet. Nevertheless, if you have a stainless steel cleaner and want to try this tip, you should first test it on an inconspicuous part of your plastic sink.
