If you live in an area with hard water, chances are you use rusty water as well, and it is one of the toughest challenges in the world of laundry. First, the clothes washed with this kind of water are dingy, dull, and stained. And it is worse if you’ve no idea of the best laundry detergent to use on this kind of water. Luckily you’ve come to the right place. You will learn why water turns rusty, the best detergent to use in rusty water, and factors to consider before buying a detergent.
The best detergent for rusty, hard water is designed not to react with calcium, magnesium, and iron. The result is soft clothes that retain their original color and last longer. In contrast, ineffective detergent reacts with the ions of these elements producing scum, resulting in dingy and stained clothes.
What Causes Water to Look Rusty?
The rusty appearance is a result of sediments and accumulated minerals. The main minerals include manganese, iron, calcium, and magnesium. Iron is especially responsible for this look as it reacts with ferric oxide, which is brown. But how does water get contaminated with these impurities?
Pipes in aged plumbing systems turn rusty over time, and this could be the source of the discoloration of your water. Another possible reason is a possible recent replacement of part of the piping with smaller sized ones, increasing the pressure in some sections.
As you open the faucet on and off, this causes pressure changes which in turn dislodges some of the rust interior surfaces of the pipe. Also, the faucet handle may be rusty and discharges some of the sediments into the faucet outlet.
Utility companies routinely conduct maintenance on their plumbing system. At the end of the maintenance, your water might get contaminated by some of the debris from the repair work. Usually, this is a temporary problem, and it takes only a short time to clear, although in some cases, it might linger on for a longer time.
Sometimes the problem might be with the water heater. If the rusty water is only coming from the hot water faucet, most likely, the water heater is suspect. Normally, water heaters have a 10-year lifespan. Beyond that, the porcelain enamel coating might wear out, exposing the steel and starting to rust. This rust will eventually find its way into your faucet.
Wells contains a lot of minerals and impurities that seep in from different sources from underground reservoirs. Common minerals in well water are manganese and iron, with the rusty appearance specifically resulting from ferrous iron, a product of a reaction between iron and water.
Another cause of the rustiness is the iron bacteria, as it corrodes iron in fittings creating a slimy brown substance.
Most of the rusty water will coincidentally be hard water due to the dissolved mineral compounds. And that is why you need detergents specifically designed not to react with the mineral compounds.
Below are some of the most effective detergents for rusty water.

Factors to Consider Before Buying Detergents
Water Softening Properties
If you live in an area with hard or rusty water, you need a detergent specifically formulated for this type of water. High-performing detergents in rusty water contain ingredients that act as surfactants to soften the rusty water for effective stain removal. Such powerful ingredients include Sodium lauryl sulfate or Sodium dodecyl sulfate, among others.
According to research studies, laundry takes quite a substantial amount of the annual household budget. So, looking for an affordable, quality detergent helps lower household budgets.
Remember, though the savings might appear inconsequential, they stack up in the long run. Luckily, most of the detergents we’ve reviewed are not only high-performing but cost-effective as well.
The best detergent should allow flexibility on how and where you can use it. The best detergent is one with an option for washing in either cold or warm water. It is especially more economical to use a detergent that allows for cold washing.
You reduce the heating cost bills and maintain the durability of the fabric. In addition, it should work with both standard and HE washing machines without compromising the quality of your laundry.
Free From Common Allergens
Some detergents cause skin itching and breathing problems, among other allergic reactions to users. Be sure to read the ingredient labels to rule out the presence of allergens before purchasing. This is especially important for households with family members who are allergic to these irritating agents. Also, be sure to check allergy-inducing dyes and fragrances.
Detergents formulated with organic or plant-based ingredients are generally considered to be eco-friendly. In contrast, chemical compounds are harmful not only to users but to the environment too.
Eco-friendliness includes packaging as well. Companies have adopted organic packaging to comply with eco-friendliness requirements. Examples of organic materials include cornstarch extracts, sugarcane-based extracts, organic fabrics, etc.
When it comes to scents, this is a tricky feature since what is a pleasant scent might be an outright turn-off to another person. So choose the scent that is not only good for you, but for your family members.
Also, remember that fragrances trigger allergic reactions, especially in children. Unlike adults, most children have not developed enough tolerance for various smells. In general, avoiding scented detergents on children’s clothes is the best thing to do.

Frequently Asked Questions
Which Is the Best Homemade Laundry Detergent for Rusty Water?
Most homemade detergents are not as effective as commercial varieties. The reason is most commercial producers have access to a wide range of ingredients not available to DIY detergent makers.
That accounts for the high performance of their detergents. That said, any formulation that contains citric acid, vinegar, or borax will soften water and make washing with hard or rusty water more effective.
More on laundry detergent alternatives here, and on mixing laundry detergent here.
Are Liquid Detergents More Effective Than Powder in Hard Water?
Powder soaps react with chemicals in the rusty or hard water to form soap scum. In comparison to liquid detergents, this makes it difficult for water to lather and be effective in the laundry. But you can improve the effect of powder detergents by adding water softening agents such as borax.
How Can I Get Old Rust Stains From a Piece of Fabric?
Vinegar or lemon juice is quite effective in removing old rust stains from fabrics. All you have to do is to spread the clothing on a flat surface, preferably over a towel. Any other piece of clothing will do. Pour a little white vinegar or squeeze a lemon juice and rub it off. That is it!
